rhoopr: icloudpd-rs - Fast iCloud Photos downloader, Rust alternative to icloudpdThe original Python icloudpd is looking for a new maintainer. I’ve been building a ground-up Rust replacement with parallel downloads, SQLite state tracking, and resumable transfers. 5x faster downloads in benchmarks, single binary, Docker and Homebrew ready.https://github.com/rhoopr/icloudpd-rs

mindcrime: This weekend I spent a lot of time on an Agent Registry idea I wanted to try out. The basic idea is that you put your Agent code in a Docker image, run the container with a few specific labels, and the system detects the Container coming online, grabs the AgentCard, and stores it in the Registry. The Registry then has (in the current version) a REST interface for searching Agents and performing other operations.But once all the low level operations are done, my plan is to implement an A2A Agent as the sole Agent listed in the AgentCard at $SERVER_ROOT/.well-known/agent-card.json, which is itself an "AgentListerAgent". So you can send messages to that Agent to receive details about all the registered Agents. Keeps everything pure A2A and works around the point that (at least in the current version) A2A doesn't have any direct support for the notion of putting multiple Agents on the same server (without using different ports). There are proposals out there to modify the spec to support that kind of scenario directly, but for my money, just having an AgentListerAgent as the "root" Agent should work fine.Next steps will include automatically defining routes in a proxy server (APISIX?) to route traffic to the Agent container. And I think I'll probably add support for Agents beyond just A2A based Agents.And of course the basic idea could be extended to all sorts of scenarios. Also, right now this is all based on Docker, using the Docker system events mechanism, but I think I'll want to support Kubernetes as well. So plenty of work to do...

absoluteunit1: TypeQuicker (https://typequicker.com) - personalized and engaging typing application.Anyone can learn to type fast - I think it just takes the right tools to make it interesting enough for the users to use daily

thrance: Cool! I found your solution a while ago while searching for something similar, do you plan to support other locales and/or keyboard layouts in the future?

ChrisMarshallNY: I'm rewriting a shipping app, that is just over two years old.This is a "full rewrite," because I need to migrate away from my previous server, which was developed as a high-security, general-purpose application server, and is way overkill for this app.Migration is likely to take a couple more years, but this is a big first step.I've rewritten the server, to present a much smaller API. Unfortunately, I'm not yet ready to change the server SQL schema yet, so "behind the curtain" is still pretty hairy. Once the new API and client app are stable, I'll look at the SQL schema. The whole deal is to not interfere with the many users of the app.I should note that I never would have tried this, without the help of an LLM. It has been invaluable. The development speed is pretty crazy.Still a lot of work ahead, but the server is done, and I'm a good part of the way through the client communication SDK.

computerex: https://github.com/computerex/dlgoGolang inference engine from scratch that can run a bunch of models with vulkan acceleration.

lpellis: https://pagewatch.ai/ - make sure LLM's can understand your site.There is a surprising amount of edge cases that can cause ChatGPT or others to misunderstand your pages. Some models can handle div based tables, some want alt tags but cannot understand title tags, etc.I built the tool to check your site as close as possible to what a human would see and then compare it with LLM's.It was a weird journey trying to tease this info out of the models, they will happily lie, skip checking sites or just make things up.

skrig: We're building a new CRM from the ground up. We've helped a handful of companies and non-profits set up CRMs and it's amazing how bad existing CRMs are. It's like they don't understand what common day to day tasks need to be made as easy as possible.We're also trying to use AI more thoughtfully than just bolting on a chatbot. We're planning to consider each workflow our customers need and how AI might help speed them up - even letting them build custom AI workflows. I think most businesses (especially smaller businesses) don't want to work at the level of Claude Code, Codex, etc. They want to work on higher level problems - build this dashboard, connect these data sources, invoice this customer, etc.Aside from that, we've noticed that the basics really matter, so we're trying to nail that first.We're definitely a bit delusional, we're just 3 people, we're doing it without funding and the competition is stiff, but we really believe in the product. Additionally, I think a lot of CRMs go south by taking on too much VC that naturally pushes them to prioritize ROI instead of continually improving the product.

tombert: I played with Jello a bit. This might be fun for a family get-together. Bookmark'd.

cheschire: Creating my own models in Blender for 3D printing. Currently creating replacement wings for a hummingbird whirligig yard decoration that broke a couple years ago. It’s a sentimental gift and I’ve hated the idea of throwing it away.Physical engineering is a huge welcome transition for me from what coding has become in the last couple years.There’s something nice about the realities of creating a model, then printing it, then seeing that exact is too exact, then reprinting, then eight more times, and then that feeling when it all comes together properly.A few weeks ago I was working on an adapter for an airbrush to use on a standard pancake air compressor. Learning to create threads in blender was really neat! I learned a lot about the physical construction of threads, something I have never put much thought into before.

ericb: A prompt injection solution that seems to benchmark better than any other approach out there, while not using hard-coded filters or a lightweight LLM which adds latency.

lpellis: Really pretty keyboard widget, though it did slightly confuse me that is showing the next key, not what I actually typed.

fastest963: I've been working on a solution to automate solar+battery use to arbitrage the market. I'm on a real-time utility plan but even if you're on TOU it can save you $1+ per day by strategically planning when to use the battery and when to conserve or charge the battery. So far it's limited to a few providers and only FranklinWH batteries but I'm eagerly looking for someone to help me get Powerwall support working and other ESS. The site is https://raterudder.com and it's open-source as well.

raybb: Lately I’ve been spending a lot of time transitioning from tech into urbanism and working on a few projects I care deeply about.- Urbanism Now - I run https://urbanismnow.com, a weekly newsletter highlighting positive urbanism stories from around the world. It’s been exciting to see it grow and build an audience. I'm thinking of adding a jobs board soon that'll be built in astro.- Open Library - I’ve been helping the Internet Archive migrate Open Library from web.py to FastAPI, improving performance and making the codebase easier for new contributors to work with.- Publishing project - I’m also working on a book with Lab of Thought as the publisher, which has been a great opportunity to spend more time working with Typst.These projects sit at the intersection of technology, cities, and knowledge sharing, exactly where I’m hoping to focus more of my time going forward.

mohsen1: I really want someone to build this:Using a webcam, monitor finger movements and find mistakes (using some sort of AI video analysis) to help user figure out how to improve. It's a hard thing to build but if you build it there is going to be paying customers. You can even sell hardware and subscriptions with it. Lots of schools want this!

mtejo: Ive been running with this little ongoing project of making little nintendo ds games with rust.I put together a pretty basic portal clone. I think its pretty cool to see it come together, animations, level creation, portal jumps.The basic hardware on the ds makes 3d pretty approachable. Ive found opengl overwhelming in the past. It seems like a fun platform to make games on, but idk if there is any active ds homebrew communities. Anyway sharing because i thought it was cool, hard to find anyone that seems to be to interested. I thought about getting a 3ds but they are surprisingly expensive now

theturtletalks: Opensource Toast alternative for restaurants

ajayvk: Have been building a project https://github.com/openrundev/openrun/ which aims to make it easy for teams to easily deploy internal tools/webapps. While creating new apps has gotten easier, securely deploying them across teams remains a challenge. OpenRun runs as a proxy which adds SAML/OAuth based auth with RBAC. OpenRun deploys containerized apps to a single machine with Docker or onto Kubernetes.Currently adding support for exposing Postgres schemas for each app to use. The goal is that with a shared Postgres instance, each app should be able to either get a dedicated schema or get limited/full access to another app's schema, with row level security rules being supported.

mkprc: Hosting and nicely typesetting some of the essays/speeches of Alfred North Whitehead on education and the role of Universities, now in the public domain. Most are from Project Gutenberg, but I've been manually transcribing a couple others.https://mkprc.xyz/public-domain/whitehead/

spudlyo: I'm writing an essay where I get into how I use GNU Emacs along with gptel (a simple LLM client for Emacs) and Google's Gemini-3 family of models to turn a 1970s-vintage text editor into a futuristic language-learning platform to help me study Latin. I want to show how I liberate poorly aligned, pixelated PDF image scans of century-old Latin textbooks from the Internet Archive and transform them into glorious Org mode documents while preserving important typographic details, nicely formatted tables, and some semantic document metadata. I also want to outline how to integrate a local lemmatizer and dictionary to quickly perform Latin-to-English lookups, and how to send whole sentences to Gemini for a detailed morphological and grammatical breakdown.I also intend to dig into how to integrate Emacs with tools such as yt-dlp and patreon-dl to grab Latin-language audio content from the Internet, transcode the audio with ffmpeg, load it into the LLM's context window, and send it off for transcription. If the essay isn't already too long, I'll demonstrate how to gather forced-alignment data using local models such as wav2vec2-latin so I can play audio snippets of Latin texts directly from a transcription buffer in Emacs. Lastly, I want show how to leverage Gemini to automatically create multimedia flash cards in Org mode using the anki-editor Emacs minor mode for sentence mining.

mohsen1: Wanted to see if AI could figure out how to compress executable binaries better than existing generic tools without me actually knowing much about compression engineering or ELF internals.The result is an experiment called fesh. It works strictly as a deterministic pre-processor pipeline wrapping LZMA (xz). The AI kept identifying "structural entropy boundaries" and instructed me to extract near-branches, normalize jump tables, rewrite .eh_frame DWARF pointers to absolute image bases, delta-encode ELF .rela structs with ZigZag mappings, and force column transpositions before compressing them in separated LZMA channels.Surprisingly, it actually works. The CI strictly verifies that compression is perfectly reversible (bit-for-bit identity match) across 103 Alpine Linux x86_64 packages. According to the benchmarks, it consistently produces smaller payloads than xz -9e --x86 (XZ BCJ), ZSTD, and Brotli across the board—averaging around 6% smaller than maximum XZ BCJ limits.I honestly have no idea how much of this is genuinely novel versus standard practices in extreme binary packing (like Crinkler/UPX).Repo: https://github.com/mohsen1/feshFor those who know this stuff:Does this architecture have any actual merits for standard distribution formats, or is this just overfitting the LZMA dictionary to Alpine's compiler outputs? I'd love to hear from people who actually understand compression math.

heimann: Link? Or a description of your approach? Sounds interesting!

YesBox: I changed gears and moved into the video games industry at the end of 2021.I started developing a city builder called Metropolis 1998 [1], but wanted to take the genre in new directions, building on top of what modern games have to offer:- Watch what's happening inside buildings and design your own (optional)- Change demand to a per-business level- Bring the pixel art 3D render aesthetic back from the dead (e.g RollerCoaster Tycoon) [2]I just updated my Steam page with some recent snapshots from my game. Im really happy with how the game is turning out![1] https://store.steampowered.com/app/2287430/Metropolis_1998/[2] The art in my game is hand drawn though

cyw: I used Rust to build a terminal based IDE for parallel coding cli workflow. It works with Claude Code, Codex and Gemini!My favorite features are: - custom layout and drag and drop to change window - auto resume to last working session on app starting - notifications - copy and paste images directly to Claude Code/Codex/Gemini CLI - file tree with right click to insert file path to the session directlyOH and it works on both Windows and MacOS! Fully open source too!https://github.com/oso95/Codirigent

jsemrau: It's a personal project, but inspired by OpenClaw (which I find way overhyped), I am building an ambient intelligence layer for investment finance including a 3-tiered memory architecture, sensors (for environment scanning), skills, reasoning agents, and a new agentic UI concept only for that purpose.I wrote about it here: https://jdsemrau.substack.com/p/pair-programming-superbill-w...

adamwong246: Testeranto - The AI powered BDD test framework for polyglot projects. There is a implementation now in ts, golang, rust, ruby, java and python. Add the language(s) that you need to your project and launch the server. Testeranto will run your BDD tests in docker and produce a set of results and logs. These logs, test results and your code are fed into an LLM, which fixes your tests for you. In essence, you write the tests and the LLM fills in the code.AM3 - (Allied MasterComputer or Artificial Mind, version 3) - An attempt to make a symbolic AI that approaches the capacities of a LLM. An LLM makes variations on the same code and schedules those variations to play in "games". The results allow the LLM to make further changes.

VonTum: I've been building high-bandwidth memory streaming interfaces for HBM on VCK5000 & U280 FPGAs in my own language - "SUS".The goal is to get consistent synthesis to 450MHz such that I can use a narrower 256-bit instead of a 512-bit interface, while maintaining full bandwidth. I've got it working at an FMax ranging 440-490MHz, though there's still some edge cases I need to hammer out.https://github.com/pc2/sus-xrt

seanwilson: An accessible color palette editor for creating branded palettes built from the ground up that pass WCAG/APCA contrast rules (which is much quicker and less of a headache compared to doing manual contrast checks and fixes later):https://www.inclusivecolors.com/The current web tool lets you export to CSS, Tailwind and Figma, and uses HSLuv for the color picker. HSL color pickers that most design tools like Figma use have the very counterintuitive property that the hue and saturation sliders will change the lightness of a color (which then impacts its WCAG contrast), which HSLuv fixes to make it much easier to find accessible color combinations.I'm working on a Figma plugin version so you can preview colors directly on a Figma design as you make changes. It's tricky shrinking the UI to work inside a small plugin window!

seeken: Selecto, an elixir SQL query library that works with or without Ecto. Also SelectoComponents which gives you a web interface to build queries.It is based on 20+ years of experience maintaining a similar system in Perl.It's on Hex.pm already, looking for people to test and comment!As Codex would say:Selecto is an open-source SQL query builder for Elixir that helps you generate complex queries from clean, domain-based configs. It supports advanced joins, CTEs, subqueries, and analytics-friendly patterns, with companion packages for LiveView interfaces (selecto_components) and code generation (selecto_mix). If your app is data-heavy, Selecto gives you SQL-level power without brittle hand-written query strings.

lawgimenez: I’ve been working on an RSS reader for macOS and iOS - https://gmnz.xyz/projects/ember-feed/It has gained a little traction in Reddit and grateful for the several paying users currently giving me lots of feedback. One of the features is that you get to import your own font using any otf, ttf files. App is 100% native too written in SwiftUI, AppKit and UIKit.I just wanted my own interpretation of an RSS Reader app, I have been a heavy user of both Reeder and NNW but the interface is just the same and I got bored a lot.

keithnz: Vibe-coded a YouTrack CLI tool in < 1 hour:https:&#x2F;&#x2F;github.com&#x2F;keithn&#x2F;ytAlso working on a language for embedded bare-metal devices with built-in cooperative multitasking.A lot of embedded projects introduce an RTOS and then end up inheriting the complexity that comes with it. The idea here is to keep the mental model simple: every `[]` block runs independently and automatically yields after each logical line of code.There is also an event&#x2F;messaging system:- Blocks can be triggered by events: `[>event params ...]`- Blocks can wait for events internally- Events can also be injected from interruptsThis makes it easy to model embedded systems as independent state machines while still monitoring device state.Right now it’s mostly an interpreter written in Rust, but it can also emit C code. I’m still experimenting with syntax.Example: module WaterTank { type Direction = UP|DOWN let direction = UP let current = 0 [>open_valve direction |> direction] [>update level |> current] [ for 0..30 |> iteration { when direction { UP -> !update level=current + 1 |> min(100) DOWN -> !update level=current - 1 |> max(0) } ~ %'{iteration} {current}' } ] [>update level |> when { 0..10 -> %'shallow' 11..15 -> %'good' 16.. -> %'too much!' then !open_valve direction=DOWN } ] }

achatham: Making my own epub reader with the kitchen sink of features I'd like. It's a speed-reading app first and foremost, using RSVP (rapid serial visual presentation, one word at a time). Also answers questions about the book with an LLM without spoilers, and can create illustrations. I've been reading _Mercy of the Gods_ lately, which has vivid descriptions of a bunch of alien races, but the pictures have done a great job supplementing my imagination. I've read more books in the past month than the last year, but we'll see if I keep it up.https:&#x2F;&#x2F;github.com&#x2F;achatham&#x2F;epub_speedread

mihijito_: I’ve been working on an rss, atom, json feed reader app that strives to make it a simple as possible to isolate what articles are meaningful for you.For now it uses UX patterns to make it easy to remove uninteresting articles and keeps a record of your read and saved articles. All locally of course.I’d like to make it into something we can share quality content with one another eventually. For now I’m focusing on making it good enough my entourage will want to use it

cperciva: Writing the release announcement for FreeBSD 14.4! The release is ready (aside from propagating to mirrors and clouds) but I have until 2026-03-10 00:00 UTC to get the announcement email ready to go out.

wonger_: I'm working on a personal recipe site called Struggle Meals, in the genre of https:&#x2F;&#x2F;traumbooks.itch.io&#x2F;the-sad-bastard-cookbook and https:&#x2F;&#x2F;old.reddit.com&#x2F;r&#x2F;shittyfoodporn&#x2F;, for food I ate when I felt too poor &#x2F; depressed &#x2F; tired &#x2F; chronically unwell. Some of them are just normal adulting recipes. Some are meal prep. Some are too struggly for a legitimate recipe site.I have some barebones content at https:&#x2F;&#x2F;struggle-meals.wonger.dev&#x2F; and will be working on the design over the next few weeks. Some decisions I'm thinking about:- balancing between personal convenience and brevity vs being potentially useful for other people. E.g. should I tag everything that's vegan&#x2F;vegetarian&#x2F;GF&#x2F;dairyfree&#x2F;halal&#x2F;etc? Should I take pictures of everything? (I'd rather not)- how simple can I make a recipe without ruining it? E.g. can I omit every measurement? should I separate nice-to-have ingredients from critical ingredients? how do I make that look uncomplicated? (Sometimes the worst thing is having too many options)- if&#x2F;how to price things? Depends on region, season, discounts, etc

Alacart: https:&#x2F;&#x2F;approximated.appIt makes connecting user domains to your app easy and reliable at any scale. Each Approximated user gets the own globally distributed, managed cluster of servers with its own dedicated IPv4 address. Includes (unlimited) edge rule features, DDoS protection, webhooks, and more. Make a simple API call, tell the user to point an A record at the IP, and it’s connected to your app with its own SSL certificates.Built&#x2F;building with elixir and phoenix, which has been fantastic.

zahlman: I've been reworking my blog to have a table of contents per article, clean CSS (something that actually looks nice and no longer relies on Bootstrap) and a few other nice things. Also taking the opportunity to fix minor errors in previous posts.Aside from that, I need to document and properly release one of the pieces that PAPER is relying on (some generic tree-processing code that makes operations on directory trees a lot nicer than with the standard library "walk"s), and work on others (in particular, a "bytecode archive" format for Python that speeds up imports for some projects, mainly by avoiding filesystem work at import time — I want to offer it as an install-time option in PAPER, and later have `bbbb` make wheels with the bytecode precompiled that way).

red_hare: I'm teaching a class in agent development at a university. First assignment is in and I'm writing a human-in-the-loop grader for my TAs to use that's built on top of Claude Agent SDK.Phase 1: Download the student's code from their submitted github repo URL and run a series of extractions defined as skills. Did they include a README.md? What few-shot examples they provided in their prompt? Save all of it to a JSON blob.Phase 2: Generate a series of probe queries for their agent based on it's system prompt and run the agent locally testing it with the probes. Save the queries and results to the JSON blob.Phase 3: For anything subjective, surface the extraction&#x2F;results to the grader (TA), ask them to grade them 1-5.The final rubric is 50% objective and 50% subjective but it's all driven by the agent.

djb_hackernews: I live in an old house.The front bump out leaks when we get driving rain. I installed some flashing but that wasn't enough, it's still leaking. So I'm working on that so I can close up the big hole in the ceiling some day.The prior owners filled in the old coal chute with literal bags of cement sort of artistically placed in the hole in the brick foundation. So I'm trying to figure out what masonry tools and skills I'll need to close it up proper.I'd like to build my kids a playhouse of some sort, sketching out some designs for that.

wonger_: Any way you could share the sketches? Seems fun and interesting.

alcazar: Working on...- Portable Secret (https:&#x2F;&#x2F;alcazarsec.github.io&#x2F;portable-secret&#x2F;) - self-contained HTML files that decrypt in the browser.- Dead Man's Switch (https:&#x2F;&#x2F;alcazarsec.com&#x2F;deadmanswitch) - sends messages when you stop checking in.- Flare (https:&#x2F;&#x2F;alcazarsec.com&#x2F;) - silent alert when your device is accessed without authorization.

wek: I'm thinking about how to maximize the speed, bandwidth of collaboration with agents and teams to get to shared context as fast as possible. I think for the human, based on biology, its visual into to the human (out from agent) and voice out of the human (into the agent). Based on this, we are working on a local, agent-native workspace where you can collaborate with your coding agent visually in your sessions, markdown, mockups, code, tasks, etc... Called Nimbalyst. Would love feedback on it.

keithnz: holy, downvotes on what I'm working on?

Mockapapella: I'm working on a TUI-based agent orchestrator called Tenex: https:&#x2F;&#x2F;github.com&#x2F;Mockapapella&#x2F;tenexIt's gone a long way to solve the "review" bottleneck people have been experiencing (though admittedly it doesn't fix all of it), and I'm in the process of adding support for Mac and Windows (WSL for now, native some other time).Some of the features I've had for a while, like multi-project agent worktrees, have been added as a part of the Codex App, so it's good to see that this practice is proliferating because it makes it so much easier to manage the clusterf** that is managing 20+ agents at once without it.I'm feeling the itch to have this working on mobile as well so I might prioritize that, and I'm planning to have a meta-agent that can talk to Tenex over some kind of API via tool calls so you can say things like "In project 2, spawn 5 agents, 2 codex, 2 claude, 1 kimi, use 5.2 and 5.4 for codex, use Opus for the claudes, and once kimi is finished launch 10 review agents on its code".

happiness0067: I'm building out https:&#x2F;&#x2F;measuretocut.com, which started as a tool for myself to help with planning board cuts (and now sheet cuts). It calculates how much material you need for your project and gives you a plan for the materials and shows all the cuts you need to make and where to make them.First release was in December for 1D cuts. Last month I released sheet cutting for 2D cut calculation. It's been working well for my own projects and it started getting consistent daily users since my last update in February. You can save projects now on the site for you to come back to later.Any feedback is welcome. I'm always looking for what features to add next.

It also has a web interface for monitoring SSL certificate of any public domain. There are a few chinks here and there. Hope I can get it over by this month.https:&#x2F;&#x2F;www.certgorilla.com

sneilan1: I'm learning how to train transformer models locally to do useful work instead of having to pay for claude. I regularly update my blog here https:&#x2F;&#x2F;seanneilan.com&#x2F;posts

czhu12: I’ve been working on an open source tool that turns your Kubernetes into a Heroku like PaaS — https:&#x2F;&#x2F;canine.sh — for about two yearsA problem that we had at my last startup was that we got stuck between not wanting to spend too much time on devops, and getting price gouged by Heroku.We were too big for the deploy to a VPS type options like coolify, but too small to justify hiring a full time Devops.Eventually a few of us had to just suck it up and learn Kubernetes properly. Was pleasantly surprised how elegant it all was.I was surprised there wasn’t something that “just worked” and plugged into our Kubernetes cluster, made it user friendly, teams, roles, etc.

Aeolun: Cool! Isometric for the win :)

akkartik: Yeah it's a nice project. Maybe it was an accidental click by somebody. I tried to compensate for it.

kilobaud: Hey I am super interested in this, got any links to check out?

lpellis: Ironically I'm getting SSL handshake failed on your site

dataviz1000: I'm using TimescaleDB to manage 450GB of stocks and options data from Massive (what used to be polygon.io), and I've been getting LLM agents to iterate over academic research to see if anything works to improve trading with backtesting.It's an addictive slot machine where I pull the lever and the dials spin as I hope for the sound of a jackpot. 999 out of 1000 winning models do so because of look-ahead bias, which makes them look great but are actually bad models. For example, one didn't convert the time zone from UTC to EST, so five hours of future knowledge got baked into the model. Another used `SELECT DISTINCT`, which chose a value at random during a 0–5 hour window — meaning 0–5 hours of future knowledge got baked in. That one was somehow related to Timescale hypertables.Now I'm applying the VIX formula to TSLA options trades to see if I can take research papers about trading with VIX and apply them to TSLA.Whatever the case, I've learned a lot about working with LLM agents and time-series data, and very little about actually trading equities and derivatives.(I did 100% beat SPY with a train&#x2F;out-of-sample test, though not by much. I'll likely share it here in a couple weeks. It automates trading on Robinhood, which is pretty cool.)

mmaunder: Nice. I played with this a bit. Agents are very good at Rust and CUDA so massive parallelization of compute for things like options chains may give you an edge. Also, you may find you have a hard time getting very low latency connection - one that is low enough in ms so that when you factor in the other delays, you still have an edge. So one approach might be to acknowledge that as a hobbyist you can't compete on lowest-latency, so you try to compete on two other fronts: Most effective algorithm, and ability to massively parallelize on consumer GPU what would take others longer to calculate.Best of luck. Super fun!PS: Just a follow-up. There was a post here a few days ago about a research breakthrough where they literally just had the agent iterate on a single planning doc over and over. I think pushing chain of thought for SOTA foundational models is fertile ground. That may lead to an algorithmic breakthrough if you start with some solid academic research.

happiness0067: As in they put bags of unmixed cement in the chute?Very exciting on the playhouse. What kind of things will it have?I'm expecting my first this year so have a ways to go before I get to work on that project

movedx: I've written and I'm now polishing and refining a tool for on-set data management for small to medium scale productions. I do Data Wrangling on the side and one of the hardest things to do is keep track of drives, backup jobs, and link them all together whilst knowing where everything is stored, who has what, how much data you have left, how much data you're going to use on the next scene given it's filmed on camera X using Y settings, and so on.It's written in Golang and acts as a simple desktop app that creates a web server and then opens the site in your default browser. This way it's easily multi-platform and can also be hosted as a SaaS for larger production houses.

tgrowazay: I tried exactly this - loading polygon.io data into TimescaleDB, and it was very inefficient.Ended up using ClickHouse - much smaller on disk, and much faster on all metrics.

happiness0067: Relateable. If I had a dollar for every time I ran into issues with time zones, that would be a profitable strategy in and of itself.

arthurcolle: did RH open up API for trading?

YesBox: Thanks! Yes, I created my own engine to maximize efficiency (where needed). I think it was the right choice for me.

idea0rbit: I’m building an observability system that tries to surface answers instead of making people dig through huge amounts of raw telemetry.The basic idea is that when one failure fans out across 20 services, you often end up with 20 alerts and 20 separate investigations, even though there is really just one root cause. I’m using distributed tracing to build a live model of how errors propagate through the system, and then exposing that context directly at each affected service.Longer term, I want this to become a very high-precision RCA engine. Right now I’m looking to try it with a few early design partners that already have a lot of tracing data, especially OpenTelemetry or Datadog APM users. I'll love to chat with some folks who would be willing to try it out!

dataviz1000: I developed a Claude skill that will interact with and press every button intercepting every request &#x2F; response on a website building a Typescript API. I only have $10 in that account so there isn't much damage that it can do. Probably get me banned but I don't use Robinhood for real trading.

Aeolun: Working on a chat app&#x2F;server and protocol builder to support it, in an attempt to use as little network as possible (e.g. dial-up should work fine).It's heavily supported by Claude Code, but much fun.https:&#x2F;&#x2F;superchat.win&#x2F;Actually not built on this yet I think, but I could switch over, haven't made anything more of it since it's still a bit rough around the edges, and I keep finding various issues during actual usage: https:&#x2F;&#x2F;binschema.net&#x2F;

gcampos: I’m working on VineWall (https:&#x2F;&#x2F;vinewallapp.com), a network tunnel that helps you fight doomscrolling by making your internet slower when it detects you spent too much time scrolling.At this moment I’m working on improving the logic that decides when&#x2F;how much to throttle the network.

happiness0067: What's the long-term support plan for dead man's switch? What happens if for example you meet an untimely fate? It seems that you will need to support storing information on a years or decades time scale right off the bat.I ask because I was recently thinking about how to preserve information for the future like this

jbonatakis: Very much mvp but I just got this all set up: https:&#x2F;&#x2F;www.pginbox.dev&#x2F;Downloaded and parsed a bunch of the pgsql-hackers mailing list. Right now it’s just a pretty basic alternative display, but I have some ideas I want to explore around hybrid search and a few other things. The official site for the mailing list has a pretty clean thread display but the search features are basic so I’m trying to see how I can improve on that.The repo is public too: https:&#x2F;&#x2F;github.com&#x2F;jbonatakis&#x2F;pginboxI’ve mostly built it using blackbird [1] which I also built. It’s pretty neat having a tool you built build you something else.[1] https:&#x2F;&#x2F;github.com&#x2F;jbonatakis&#x2F;blackbird

shepherdjerred: I've been migrating my projects from Dagger to Bazel. It's... slowly making progress. Claude really wants to take shortcuts and I've never used Bazel before.https:&#x2F;&#x2F;github.com&#x2F;shepherdjerred&#x2F;monorepo

jerrygoyal: I built a lightweight (<1mb) chrome extension (with over 600,000 downloads) that lets you chat with page, draft emails and messages, fix grammar, translate, summarize page, etc.. You can use models from OpenAl, Google, and Anthropic.Yes, you can use your own API key as well.

Years of tableau&#x2F;looker have atrophied my creativity a bit, trying to get back to having more fun.

sentinel1909: Against my better judgement, I'll post this landing page to a tool I'm working on:https:&#x2F;&#x2F;wasm-drydock.devAbout an hour ago I was dismissed as AI slop on the r&#x2F;rust Reddit. Whatever.This tool is my line of defense in case `trunk` goes dead, which it seems to be increasingly likely. It helps me build fullstack sites using Actix Web and Yew.Using it now to see if I can re-invent my blog site for the umpteenth time. :)

alexsparrow: I'm building open source homebrewing (as in beer) software at https:&#x2F;&#x2F;www.brewdio.beer. It's something I've poked at periodically for a few years but now I'm using AI to see how far I can take it.It has a few core libraries built in rust with a web app and a terminal UI. Android app is in the works. The persistence layer is intended to be offline first using a CRDT with an optional sync server. I'm also trying to integrate "bring your own AI" assistants to help tweak recipes or make suggestions.It's been a fun way to sharpen my claude skills but also to see how feasible it is to maintain multiple frontend applications with a large amount of shared code. Still a lot to do, particularly the core calculations are not yet on par with existing offerings.

kacy: I’ve been consumed by building https:&#x2F;&#x2F;emberdb.com https:&#x2F;&#x2F;github.com&#x2F;kacy&#x2F;ember over the last few months.It’s a drop-in replacement for Redis written in Rust. Most if not all of your client code should work without issues. Outperforms in many areas and has more out of the box features like proto storage, raft&#x2F;swim, and encryption at rest.I’m pretty proud of it, and I hope you’ll give it a shot and open bug reports. :)

tarokun-io: Mostly Jolteon (https:&#x2F;&#x2F;github.com&#x2F;lautarodragan&#x2F;jolteon), a TUI music player written in Rust (for almost 2 years now!)Also used the new Navigation API (and some Shadow DOM) to build a cheap, custom client-side rendering (sort of) into my site (https:&#x2F;&#x2F;taro.codes), and some other minor refactors and cleanup (finally migrated away from Sass to just native CSS, improved encapsulation of some things with Shadow roots, etc).I've been wanting to write a simple AI agent with JS and Ollama just for fun and learning, but haven't started, yet...

BohdanPetryshyn: Five months into building product analytics for conversational AI. Started by targeting vibe coding tools like Lovable but realized most of them don't care about user experience yet. With monthly churn over 50%, they focus on acquisition, not retention.Now shifting to established SaaS companies adding AI assistants to their existing products. Some of them literally have people reading chats full time, so they actually value the experience.Building https:&#x2F;&#x2F;lenzy.ai - 2 paid customers, 2 pilots, looking for more and figuring out positioning.

aguacaterojo: Last week I wrote the spec for a couple of vanilla JS https:&#x2F;&#x2F;danielgormly.github.io&#x2F;primavera-ui&#x2F;dnd&#x2F; that I've handwritten in the past. I used the spec to vibecode them + a few follow-up correction prompts. Honestly the robot did a better job of implementation than I would have. Just can't compete with the speed.Very early days but will keep updating them & adding more.

alcazar: If we were to die as a company (unlikely), we would reach out to customers well in advance (think >1 year) and ask them to download their data so they could migrate to another provider.This seems unlikely, however, since our infrastructure costs for the dead man's switch are covered by just a handful of subscriptions. Besides, we host it next to our other more profitable main product, so it gets free maintenance.We are up for the challenge of making this last for many decades, though. It is a beautiful mission.

TheAceOfHearts: I vibe coded a tiny MUD-style world sim where LLMs control each character. It's basically a little toy sandbox where LLMs can play around. There's no real goal to this, I just thought that it would be fun, like a more advanced tamagochi.One of the issues I encountered initially was that the LLMs were repeating a small set of actions and never trying some of the more experimental actions. With a bit of prompt tweaking I was able to get them to branch out a bit, but it still feels like there's a lot of room for improvement on that front. I still haven't figured out how to instill a creative spark for exploration through my prompting skills.It has been quite exciting to see how quickly a few simple rules can lead to emergent storytelling. One of the actions I added was the ability for the agents to pray to the creator of their world (i.e. me) along with the ability for me to respond in a separate cycle. The first prayer I received was from an agent that decided to wade into a river and kneel, just to offer a moment in stillness. Imagining it is still making me smile.Unfortunately, I don't have access to enough compute to run a bigger experiment, but I think it would be really interesting to create lots of seed worlds &#x2F; codebases which exist in a loop. With the twist being that after each cycle the agents can all suggest changes to their world. This would've previously been quite difficult, but I think it could be viable with current agentic programming capabilities. I wonder what a world with different LLM distributions would look like after a few iterations. What kind of worlds would Gemini, Claude, Grok, or ChatGPT create? And what if they're all put in the same world, which ones become the dominant force?

wisemang: Nice! I’ve been working on https:&#x2F;&#x2F;treeseek.ca which is a different use case from most of the other open data tree sites I’ve seen — I want to be instantly geolocated and shown the nearest trees to me. I do a lot of walking and am often mesmerized by a particular tree, and I wanted something to help me identify them as quickly as possible, with more confidence and speed than e.g. iNaturalist (which i do also use).This is an app that’s been bouncing around in my head for over a decade but finally got it working well enough for my own purposes about a year and a half ago.

tarokun-io: Metropolis 1998 looks beautiful! (and addictive!)Will you do a native Linux release, or has it been tested with Proton?Also, just from watching the video and screenshots in the Steam page, it seems like a crazy amount of work. Are you doing everything by yourself?

oooyay: I've been building https:&#x2F;&#x2F;lan.events. It's been built entirely with an LLM as I've been learning more concepts behind agentic engineering for reliable development with an LLM. The primary reason I built it is because LANs are disappearing and they were a formative part of my childhood. They were a way to connect with people that I knew from all over the world. I still have some lasting friendships from the big and small LANs I went to as a kid. LANs are free for 50 and under so please sign up and if you have feedback, send it through the support system!

Robdel12: I wanted a real native app (iOS&#x2F;macOS) as a client for my agents and to be able to truly control &#x2F; mange them from it. So, think Claude Code remote but not just Claude and a proper native app. Or the Codex app but actually native.The server is a rust binary so you can toss it on any container&#x2F;computer and connect to it in the app.My philosophy isn't to replace my other tools I love like emacs, ghostty, etc. But I am taking a stab at "real time code review" and have some crummy magit-like code review built in that I need to revisit.https:&#x2F;&#x2F;github.com&#x2F;Robdel12&#x2F;OrbitDock

yeag123: I’m working on a tool to automate manual document workflows, specifically for industries like manufacturing where accounting paperwork is still a manual burden.The workflow: Upload doc → LLM extracts structured data → Generate new doc from template.It’s API-first, includes webhooks, and is built to be self-hosted&#x2F;self-provisioned for privacy. Still very much a WIP, but looking for feedback on the feature set and the extraction accuracy.URL: https:&#x2F;&#x2F;fetchtext.io

The main thing I'm working on to that effect is https:&#x2F;&#x2F;homelore.orgIt's like a carfax but for your home, although the intention is more to create an interesting historical narrative that inspires people to care about the history of their home rather than as a tool for inspecting home issues before buying.My target customer is realtors who want to inspire buyers to take on historic homes that may need a lot of work. Also home owners themselves of course.

zabi_rauf: One month ago, I purchased this small eink reader (Xteink 4) and I've been loving reading on that device. It made me read much more in the past month (already more than 50% through Fall or Dodge in Hell).The stock firmware is horrible but the community has this firmware called CrossPoint. I wanted to be able to upload, manage files etc. from my iPhone on the go and also send over web articles. So I build this app CrossPoint Sync https:&#x2F;&#x2F;crosspointsync.com to do just that.I've already published it on App Store and pending publishing on Android. The community is niche and has also been using the app, so its been fun building for my use and in turn also getting good feedback from community.If you are using the Xteink and CrossPoint firmware, then give the app a try.iOS App Store: https:&#x2F;&#x2F;apps.apple.com&#x2F;app&#x2F;crosspoint-sync&#x2F;id6758985427Android Beta: https:&#x2F;&#x2F;crosspointsync.com&#x2F;android&#x2F;join-betaGitHub: https:&#x2F;&#x2F;github.com&#x2F;zabirauf&#x2F;crosspoint-sync

ontouchstart: When I discovered that some local llama.cpp can OCR PDF images generated by TeX, I started to revisit literate programming defined by Donald Knuth and explore using PDF as the source of truth artifact (instead of Markdown or program source code itself) for LLM to consume.I only got to the point of having code and data as \verbatim in \LaTeX. Next step is CWEB.Here is an example (with C and Rust code in \verbatim)https:&#x2F;&#x2F;ontouchstart.github.io&#x2F;rabbit-holes&#x2F;llm_rabbit_hole_...The ultimate goal is machine and human readable proofs on algorithms.

chhs: I'm working on JRECC, a Java remotely executing caching compiler.It's designed to integrate with Maven projects, to bring in the benefits of tools like Gradle and Bazel, where local and remote builds and tests share the same cache, and builds and tests are distributed over many machines. Cache hits greatly speed up large project builds, while also making it more reliable, since you're not potentially getting flaky test failures in your otherwise identical builds.https:&#x2F;&#x2F;jrecc.net

When the V1 is ready I’m planning to do a Show HN with this account.It's my first product.

arjunnvl: Been building https:&#x2F;&#x2F;textkit.dev&#x2F; for the past week.It's a collection of 40 (and growing) tools for text processing, data cleaning, conversions, dev utils etc. Everything runs in the browser and is completely free.Started this partly to learn SEO from scratch on a fresh domain, partly because i am lazy with regards to doing basic data cleaning using pandas and i found myself repeatedly using similar online tools that are completely riddled with ads.I built this using Flask + Vanilla JS. I don't think there was any need to overcomplicate it. And for fun, i vibe coded a windows 95 desktop mode where all the tools open as draggable windows.

dhruv3006: I am working on Voiden : Api client based on executable markdown !Check it out here : https:&#x2F;&#x2F;github.com&#x2F;VoidenHQ&#x2F;voiden

rahimnathwani: When GPT-4.5 came out, I used it to write a couple of novels for my son. I had some free API credits, and used a naive workflow:while word_count < x: write_next_chapter(outline, summary_so_far, previous_chapter_text)It worked well enough that the novels were better than the median novel aimed at my son's age group, but I'm pretty sure we can do better.There are web-based tools to help fiction authors to keep their stories straight: they use some data structures to store details about the world, the characters, the plot, the subplots etc., and how they change during each chapter.I am trying to make an agent skill that has two parts:- the SKILL.md that defines the goal (what criteria the novel must satisfy to be complete and good) and the general method- some other md files that describe different roles (planner, author, editor, lore keeper, plot consistency checker etc.)- a python file which the agent uses as the interface into the data structure (I want it to have a strong structure, and I don't like the idea of the agent just editing a bunch of json files directly)For the first few iterations, I'm using cheap models (Gemini Flash ones) to generate the stories, and Opus 4.6 to provide feedback. Once I think the skill is described sufficiently well, I'll use a more powerful model for generation and read the resulting novel myself.

jasondigitized: How did you go from 0 users to 3,500? Genuinely curious how people get their games off the ground.

varworld: Current working on two new products:* https:&#x2F;&#x2F;sprout.vision&#x2F; - AI generated Go-To-Market Strategy for launching your next venture. I have a Tech background with limited GTM experience, so I experimented with AI to learn about different strategies and decided to turn it into a simple product that will generate a comprehensive plan (500+ pages) to help you launch your next venture. Try it out, would love to hear your feedback, use the HN50 promo code for 50% off your order.* https:&#x2F;&#x2F;pubdb.com&#x2F; - Reviving a 10 year old project, it’s meant to make research publications more accessible to mere mortals with the help of AI. I have lots of ideas I want to try out here but haven’t gotten around to it yet. Currently focused on nailing down the basics with an OCR indexing pipeline and generating AI summaries.

petersonh: I've been building a little io style game since Christmas, it's been fun!https:&#x2F;&#x2F;hovertag.io&#x2F;My kid played it, and didn't stop for 45 minutes so I think that's a win :-)

diasks2: I've been working on two small projects recently.1. Live Kaiwa — real-time Japanese conversation supportI live in a rural farming neighborhood in Japan. Day-to-day Japanese is fine for me, but neighborhood meetings were a completely different level. Fast speech, local dialect, references to people and events from decades ago. I'd leave feeling like I understood maybe 5% of what happened.So I built a tool for myself to help follow those conversations.Live Kaiwa transcribes Japanese speech in real time and gives English translations, summaries, and suggested responses while the conversation is happening.Some technical details:* Browser microphone streams audio via WebRTC to a server with Kotoba Whisper * Multi-pass transcription: quick first pass, then higher-accuracy re-transcription that replaces earlier text * Each batch of transcript is sent to an LLM that generates translations, summary bullets, and response suggestions * Everything is streamed back to the UI live * Session data stays entirely in the browser — nothing stored server-sidehttps:&#x2F;&#x2F;livekaiwa.com---2. Cooperation Cube — a board game that rotates the playing fieldYears ago I built a physical board game where players place sticks into a wooden cube to complete patterns on the faces.The twist: the cube rotates 90° every round, so patterns you're building suddenly become part of someone else's board. It creates a mix of strategy, memory, and semi-cooperative play.I recently built a digital version.Game mechanics:* 4 players drafting cards and placing colored sticks on cube faces * The cube rotates every 4 actions * Players must remember what exists on other faces * Cooperation cards allow two players to coordinate for shared bonuses * Game ends when someone runs out of short stickshttps:&#x2F;&#x2F;cooperationcube.com---Both projects mostly started as things I wanted to exist for myself. Curious what people think.

kaiwenwang: I like simplescraper. It reminds me of (https:&#x2F;&#x2F;www.withparse.com&#x2F;) and (https:&#x2F;&#x2F;www.parse.bot&#x2F;)It suggests to me that the underlying architecture probably isn't too complicated, so I'd wish for an open-source solution

yboris: Got delayed on my 8th anniversary release of Video Hub App - hoping to get it out in March &#x2F; April. I have some bug fixes and new features in my app for browsing and organizing video files across local and network drives.https:&#x2F;&#x2F;videohubapp.com&#x2F; & https:&#x2F;&#x2F;github.com&#x2F;whyboris&#x2F;Video-Hub-App

Folcon: I've been slowly hacking on game ideas on and off for the better part of a decade and I've finally switched tracks and trying to seriously build something full timeIt's a bit scary basically 180ing like this but I figure if I don't try it now I never willI've already started prototyping various ideas, and to be honest just sitting down and spending time doing this has been really quite lovelyOne thing I'm finding fun is slowly unearthing what I actually find interestingI started with messing around in minecraft and tinkering with rimworld-like game ideas, but I'm slowly moving away from them as I've been tinkering more and moreDon't get me wrong, I do want to revisit them at some point in the future, but I do find myself circling more around narrative, simulations and zachlikesIt's a bit of an odd mix and in some ways they look like paradox style games, but I'm well aware that taking one of those behemoths on is going to be a bit silly, so I'm trying to slim down until I get to a kernel that I actually find enjoyable tinkering withA toy if you willCurrently I'm trying to work out if there's anything interesting in custom unit design, basically unpicking how games like rollercoaster tycoon's coaster design maps to stats like excitement ratings and seeing how that might mix with old school point buy systemsIt feels like it might be small enough to be a good toy and I'm having fun tinkering with it, but I have no idea whether other people will xDIt might honestly be too niche for anyone and I've successfully optimised for an audience of one :shrug:

jaredwiener: Building a new kind of news site, featuring updates from primary sources.We're constantly pulling info from official sources, and using AI to group and summarize into stories, and continue to share reporting from trusted, vetted journalists.The result is news with the speed and breadth of getting updates straight from the source, and the perspective and context that reporting provides.Still ramping up, but I'd love to hear feedback:https:&#x2F;&#x2F;www.forth.news

swaraj: V cool, this is a perfect llm use case

jaredwiener: thank you -- great to hear!

nswizzle31: I love the idea and am working on something similar around getting more IRL events out in the world with https:&#x2F;&#x2F;onthe.townI do wonder if the problem is not so much having a place to find LAN events but actually just having enough people put on LAN events in the first place. It feels like a thing of the past with how much less people interact in person these days. It's a shame because LANs are awesome!Have you thought about ways to make it easier for people to host LAN events? Or does this solve that as well? I guess a solution would require matching random people together. Happy to discuss more - nick at onthe.town

swaraj: So many things these days I just love being an engineer rn - ai scheduling assistant - polymarket trading bots - ai assisted form filler - games my 6 y&#x2F;o dreams up - openclaw workflows - and countless hackathon-y projects at work that never would have seen the light of day without my best friend Claude

suzdude: I don't play every day, but I've been a big fan of Tiled and showed it to a number of other folks.Thank you so much for keeping it going!

paulhebert: Thanks for playing and sharing!

pedrosbmartins: I've been working on a surfing game on my spare time for the past year. The idea is to keep it closer to the real sport, focusing on pumping, carving, nose-riding, etc. I shared a video of it on the Unity3D subreddit[1] and the feedback was quite positive, so planning on getting a demo ready as soon as possible![1] https:&#x2F;&#x2F;www.reddit.com&#x2F;r&#x2F;Unity3D&#x2F;s&#x2F;mB2kn0BxIT

rotub: I'm making a PC game called Doggy Don't Care. You're a dog left at home alone getting up to mischief https:&#x2F;&#x2F;store.steampowered.com&#x2F;app&#x2F;2438180&#x2F;Doggy_Dont_Care&#x2F;

CalChris: Canadian c3 citizenship application.

planckscnst: I'm working on "context bonsai" which is currently a plugin for OpenCode that allows the LLM to self-edit its own context. It works like compaction, but it can retrieve back the compacted info if needed. And it's not just when the context is completely full, and it doesn't compact the entire context - it picks messages &#x2F; tool calls where the details are no longer necessary, like a debugging session that is already solved or feature implementation that is complete and you've started on implementing the next feature.I've also used tweakcc to make this work in Calude Code and plan to also do one for open source coding agents - codex, pi, Gemini, etc. And I'm also doing Livestreams of the development process.https:&#x2F;&#x2F;github.com&#x2F;Vibecodelicious&#x2F;opencode

paulhebert: It's been a gradual process over the last 5.5 months. Here are some of the things that worked for me:- I applied to showcase the game at the Portland Retro Gaming Expo with the Portland Indie Game Squad. They accepted me so I was able to showcase it at the expo for a day. This got me some players right off the bat- I shared it on HN, Reddit, Mastodon, etc.- The website Thinky Games wrote an article about it- The YouTube channel Cracking the Cryptic shared it which got a lot of new players. More recently a couple of other YouTubers (Timotab and Stro Solves) have been posting videos regularly- I link to it from my blog, and this unrelated rant went semi-viral in web dev circles: https:&#x2F;&#x2F;paulmakeswebsites.com&#x2F;writing&#x2F;shadcn-radio-button&#x2F;- Winning the award gave me more visibility and playersI've also tried using things like Instagram and Discord but haven't had much luck there. I don't really get how those platforms work.To be honest I'm not great at marketing. I've just been experimenting and seeing what works.---I would say the most important thing is the game itself:- I've worked hard to gather feedback and incorporate it into the gameplay.- I focus on keeping the puzzles fresh and striking the right difficulty level. (Challenging but something most people can do in 10 minutes.)- I built a sharing feature that ~300 or so people use a dayI think all my marketing would have been useless if people didn't like the game and want to play again and share it with their friends.

Rohunyyy: I built a simple joke tool to analyze all the rejection emails (over 1600) that I got during the recent job searches and create simple bar graphs from it. Wrote a blog about it https:&#x2F;&#x2F;github.com&#x2F;khante&#x2F;l here https:&#x2F;&#x2F;rohankhante.substack.com&#x2F;p&#x2F;thank-you-for-your-applic....PS - The results are entirely obvious.

medbar: I just finished adding uACPI to my hobby OS and have all the pieces necessary to write up a crude version of Pong. Since pong was my first ‘real’ project when I started teaching myself how to code, this has that extra bit of sentimentality for me :)

sarthaksaxena: https:&#x2F;&#x2F;llmpm.coI have built npm for LLM models, which lets you install & run open sourced models The idea is to make models installable like packages in your code:llmpm install llama3llmpm run llama3You can also package models together with your code so projects can reproduce the same setup easily.Github: https:&#x2F;&#x2F;github.com&#x2F;llmpm&#x2F;llmpm-dev

chunqiuyiyu: Continue improving my Chinese-character spelling game: https:&#x2F;&#x2F;store.steampowered.com&#x2F;app&#x2F;4218330&#x2F;WordJoy&#x2F;

sidrag22: https:&#x2F;&#x2F;beanhoard.com&#x2F;Coffee Roaster Aggregation ETL using fastapi, nextjs, bs4 etc etc. It's been fun, just finished up the oauth for discord that pairs nicely with the info required to make Discord dm notifications function. attempting to charge 6$ for the instant notifications, but doubt many people will be interested. up to 75 roasters and all of them are checked every 10 mins for new products.Considering reusing the repo as a framework for other industries if this project ever gains any traction. Also was considering adding a goofy rag discord bot to the server just because i love tossing in a rag layer everywhere lately, and feel like i fall a bit short on my filters for stuff like origin&#x2F;flavor notes and all that junk. Semantic search with solid chunk strategies might create a better solution than if i did get all the filters working as well as possible.

daliusd: Invoicing app for individual workers in Europe. Currently I am focused on compliance (it is Europe after all)). Check it here: https:&#x2F;&#x2F;www.haiku.lt

asim: For about a year I've been working on Mu - an app for everything without ads, algorithms or exploits. https:&#x2F;&#x2F;mu.xyzBlog, news, chat, video, mail, web. Basically all the daily habits as little micro apps in one thing. I find it quite useful. Not sure anyone else does yet though.Also separately worked on Reminder.dev which is a Quran app and API that bakes in LLM based search and motivational reminders.

siliconc0w: https:&#x2F;&#x2F;taxmax.dev - AI tax agent that helps teams optimally classify their spend - we're looking for design partners if you want a free report.

friggeri: I’ve been training an alphazero style model for an abstract strategy game I created 20 years ago. It’s been really fun learning about MCTS and figuring out how to optimize all parts of the pipeline to be able to train on ~millions of moves for ~hundreds of dollars.

adamgoodapp: Looks amazing, added to my wish list!

richstokes: “Like carfax but for your home” is a really interesting idea. So many homes are bought with little-to-no history beyond an inspection of questionable thoroughness.If this became the norm, somehow, it would be a really helpful tool for both buyers and sellers.

spooneybarger: More stuff for pony than you can shake a stick at.

andrewstuart: I made an AMQP message queue which implements only the most commonly used stuff.It has one SQLite database per queue.In golang.Why? Because Rabbit is slow and resource hungry and needs configuration.

popupeyecare: Im building https:&#x2F;&#x2F;trypixie.com to legally employ my 7 year old child, save on taxes and contribute to her Roth IRA.Im also building https:&#x2F;&#x2F;www.keepfiled.com, a microsaas to save emails (or email attachments) to google driveI almost forgot, I also built https:&#x2F;&#x2F;statphone.com - One emergency number that rings your whole family and breaks through DND.I love building. I built all these for myself. unfortunately I suck at marketing so I barely have customers.

Reforest8973: TryPixie is a great idea

memset: I just built a little tool that takes a Fora itinerary as input and creates a google calendar (.ics) feed as output.https:&#x2F;&#x2F;itinerary.projects.jaygoel.com&#x2F;

sarthaksaxena: https:&#x2F;&#x2F;llmpm.coI have built npm for LLM models, which lets you install & run 10,000+ open sourced large language models within seconds. The idea is to make models installable like packages in your code:llmpm install llama3llmpm run llama3You can also package large language models together with your code so projects can reproduce the same setup easily.Github: https:&#x2F;&#x2F;github.com&#x2F;llmpm&#x2F;llmpm-dev

automathematics: I’m making an RPG Engine&#x2F;toolset (i.e. Final Fantasy SNES or Game boy) that targets iOS&#x2F;Android and the tools themselves are shippable in the mobile client (or web if you want some actual screen real estate)

jpsimons: I'm building an image editor for macOS. Don't really like Affinity or GIMP so thought I'd go ahead and make my own. https:&#x2F;&#x2F;skullrocksoftware.com

taylorhou: A bunch of ideas that have had domains but never enough engineers. Now there isn't enough time it seems except when I've hit my LLM subscription limits and they need to cool down.Already launched biz-in-a-box.org and a life-in-a-box.org spinoff as frameworks to replace every entity's QuickBooks. I'm using them myself for every project my agents are spinning up.Stealth project is related to classpass but for another category of need that won't go away even in the age of AI that really is only possible with critical mass of supply to meet existing demand. Super excited cus there's no better time to build with unlimited agents that scale without people problems.Lastly, can't wait to run local LLMs so no longer limited by tokens&#x2F;money.

ChicagoDave: Completed:- http:&#x2F;&#x2F;sharpee.net : Text Adventure authoring platform in Typescript- https:&#x2F;&#x2F;github.com&#x2F;ChicagoDave&#x2F;tsf : A multi-target npm build tool- https:&#x2F;&#x2F;devarch.ai : Claude Code guardrail workflow including hooks, agents, and skillsIn progress:- unnamed project to disrupt commercial site hosting including a new marketplace

101008: Not sure if people interested, but since I use sqlite in a lot of my own projects, I am working on a lightweight monitoring and safety layer for production SQLite.The idea is pretty simple: SQLite is amazing, but once it’s running in production you basically have zero observability. If something weird happens (unexpected writes, schema changes, background jobs touching tables, etc.) you only find out after the fact. It tries to solve that without touching application code. It's a Rust agent that runs next to your sqlite file, and connects to the server where everything is logged in. My current challenge right now is encryption and trust, mostly.Curious if others here are running SQLite in production and if you would be interested in something like this.

rsalus: what does devarch do exactly? why not OSS?

instagib: Looks good so far. The AI summary button is nice but hard to distinguish from the background.

ynac: * Remote viewing stock market trading programs - One version is with a buddy who shows me a colored board depending on the outcome for the week. The other is a solo version using a Swift app on Mac. We're just out of buggy beta (the analog version was laughably more difficult to get clean. We'll see if either works and which one wins.* Telephone handset for my mobile phone with side talk.* First draft of a book &#x2F; workbook on Work Flow. Outcrop of the work flow consulting I do, stuff I've learned, and so on.* Short film script - trying to convince a local actor to play the lead before we lose the rainy season here - otherwise we'll need special effects or just wait until the fall.* Polishing firmware, OSX, and iOS suite for a wearable neuromodulator unit. Deadline in a week!* Nmemonic community and app - been poking at this for years and finally had a breakthrough on the UI. My first app to release in the wild, so pretty exciting.

majicDave: I’m working on a new internet.There is a Vulkan based browser which you can use to connect to the only public site so far, a playable breakout clone.https:&#x2F;&#x2F;github.com&#x2F;mjdave&#x2F;katipo

upmostly: I'm building DB Pro, a better database client.I just released support for dashboards. I've kept a devlog for the past 6 months.https:&#x2F;&#x2F;youtu.be&#x2F;EEA73e6MH1cAnd the biggest update is coming soon, DB Pro Cloud, which will let you connect to and manage any database through your browser as well as collaborate with your team.Imagine Postman but for databases.https:&#x2F;&#x2F;dbpro.app

ramoz: Side project - plan mode and code review annotations for coding agents (ui that integrates via hooks): https:&#x2F;&#x2F;github.com&#x2F;backnotprop&#x2F;plannotatorMain gig: Trusted agents. We just shipped hardware based signing to web bot auth protocol.

kameama: A 16×16 multiplication table that encodes quoting, evaluation, branching, recursion, an 8-state counter, and IO — all as lookups in the same table. 83 Lean theorems, zero sorry. The project asks: can a finite algebra with a single binary operation be forced by axioms to contain its own representation layer? The answer is yes. Axiom-driven SAT search finds the constraints, Lean verifies the witness. I should be upfront: Claude wrote most of the Lean proofs and Z3 search scripts. My role was the ontological framework, the axiom design, and deciding what to search for and why. The AI-human split was roughly: I provided the "what should exist and why," Claude provided the "here's the code that proves&#x2F;finds it." Every Lean theorem compiles independently regardless of who typed it. Universal results (hold for all satisfying algebras, not just this table): every model is rigid, judgment and synthesis provably cannot commute, and the tester's acceptance partition carries irreducible information that structure alone can't determine. The specific table fits in 256 bytes and can be recovered from a shuffled black-box oracle in 62 probes. https:&#x2F;&#x2F;github.com&#x2F;stefanopalmieri&#x2F;Kamea

hawtads: We are building an agentic ad tech system optimized for real time and scale. The process of making an ad, from ideation to distribution, is traditionally exceptionally labor intensive. We are making it possible to target, design, and distribute ads at scale and in real time.https:&#x2F;&#x2F;hawtads.com

8organicbits: I made a web-based speaking clock: https:&#x2F;&#x2F;alexsci.com&#x2F;time-at-the-tone&#x2F;I had been doing lots of time-based work for a blog post and ended up annoyed that so many clocks around me were visually out of sync. Especially my microwave and oven clocks. Using the tool I got them synced up beyond what I could perceive.

wmeredith: PC Part Picker for hi-fi stereos: https:&#x2F;&#x2F;buildhifi.com&#x2F;I've wanted this for a long time, so I finally started building it. I've had a lot fun!- Graph-based signal flow: Products become nodes, connections are edges inferred from port compatibility (digital, analog, phono, speaker-level domains)- Port profile system: Standardized port definitions (direction, domain, connector, channel mode) enable automatic connection inference- Rule engine: Pluggable rules check completeness, power matching, phono stage requirements, DAC needs, and more

xeo84: I'm working on version 3.0 of my feed reader app NewsNinja: https:&#x2F;&#x2F;ainews.ninjaVersion 3 will add more feed types: Podcasts, Mastodon, Twitter&#x2F;X, Calendar, Reminders, Weather, Finance tickers and more.It will have a new UI, new features like notifications and local transcripts and summaries and many quality of life improvements.

brynnbee: I made an idle version of the 1999 MMORPG "EverQuest". There's maybe around 50 people playing at any given time and has a enthusiastic discord group for it. It's relatively fully-featured to the original game, and has a lot of new mechanics to make the idle format work well. The 3D graphics aspect of it is really more of a screensaver, though, and all game interactions are done through menus.I recently converted a bunch of stuff to be client side instead of server side (turns out running a real-time MMORPG server is expensive) so there's a new round of bugs I'm still resolving, but it's still fun to play:https:&#x2F;&#x2F;www.idlequest.net&#x2F;

tmilard: No-code tool :From 30 photos --> FPS video game visit.Example : https:&#x2F;&#x2F;shorturl.at&#x2F;We3dH

imazio: I am working on https:&#x2F;&#x2F;yakki.ai, a Mac dictation app. I have started expanding what the users can do with it, for the moment you can record your meetings and get insights and notes. I am considering where to take it from here! competition is fierce, so I am focusing on making it better and to serve specific users that provide feedback.

jpsimons: Thanks! I'm hand drawing all the icons which is slow going, but I'm drawing them in Mojave Paint. Nothing better than eating your own dogfood.

curo: An interactive Greek & Roman Mythology course: https:&#x2F;&#x2F;www.scrivium.comIf we can nail this one, then an entire Oxford-grade education in the same style.

_el3m3n7: Love the concept! I would love it even more if you could add support for SteamDeck&#x2F;proton

thewoodsman: There is something so wildly cool about having an idea, modeling it, and a few hours later holding a physical instantiation of the thing that previously just existed in your head. Something we software people don't get to experience often enough.

nisalperi: We are building a live knowledge graph of all political players in the South Asian Region. Essentially mapping out entities, relationships, and events with data from the last 30 years or so.

bryanhogan: Published a post that contains all of the blog posts by other people that I shared in my monthly mail-letter: https:&#x2F;&#x2F;bryanhogan.com&#x2F;blog&#x2F;other-cool-blog-posts-2026Also moving to Sveltia as my CMS (Astro markdown blog), after exploring multiple other options. Changed the structure of my Obsidian vault, will write about that also.I’m also still working on a few projects:- https:&#x2F;&#x2F;dailyselftrack.com&#x2F;- https:&#x2F;&#x2F;game.tolearnkorean.com&#x2F;- https:&#x2F;&#x2F;app.tolearnjapanese.com&#x2F;- https:&#x2F;&#x2F;tolearnkorean.com&#x2F;

woutr_be: I wrote this little web app over the weekend, the idea was to make you think about your next purchase by introducing a 48 hour countdown. In 48 hours you come back and decide if you really need this product, or if it was just an impulse buy.All data lives in your browser (IndexDB) - https:&#x2F;&#x2F;buyitlater.vercel.app

dzink: If everything is local, why the subscription? That 150 is instant incentive for me to prompt my own on Claude and get a more personal outcome right away. Margin comes from a moat, and local LLM is the opposite of that, especially if you need internet to verify subscription for local use at any point.

pranaywankhede: I am working on making product managers more aware about what kind of personality they are. I have seen there are couple of tests but those are not the ones that will put people into the actual work of Product Management.So I built a test for the same and its called Orlog. You can check it out here: https:&#x2F;&#x2F;orlog-test.netlify.app&#x2F;Looking for your feedback.

do_anh_tu: I wrote this Telegram bot that translates any video with AI-generated subtitles in about 2 minutes. You paste a YouTube, TikTok, or Instagram link, pick your language, and get back the video with burned-in subtitles.It started because my wife watches Chinese dramas and new episodes never have subtitles for our language.

_caw: I've been plugging away on MadHatter (https:&#x2F;&#x2F;madhatter.app), a web tool for knitting&#x2F;crochet projects. It works best on desktop!Why? Many yarncrafters painstakingly build spreadsheets, or try to bend existing general purpose pixel editors to their will. It's time consuming & frustrating.Along the way, I've solved a bunch of problems: - Automatic decreases (shapes the hat) &#x2F; overstitching markers (shows when multiple colors are used in the same row) - Parameterized designs, like waves, trees, geometric shapes. No more manually moving an object by a couple of pixels, it's a simple click & drag. - Color palette merging (can't delete a color if you already use it in a pattern!) - Export to PDF (so you can print it or stick it on a tablet) - Repeat previews (visualize the pattern as it repeats horizontally) The core feature that makes this more useful than most general purpose editors is that the canvas is continuous.If you drag a shape near the right edge of the canvas, you'll see it "wrapping around" onto the right edge.This reflects the 3D reality of a hat!

nwyin: too many things in flight!inspired by the karpathy&#x2F;twitter posts on running (semi) autonomous research loops, I build https:&#x2F;&#x2F;github.com&#x2F;tnguyen21&#x2F;labrat to be able to try and replicate some paper results over night. still early stages but I'm getting some use out of it already.also spending a lot of time thinking about how you "close the loop" on software projects. right now figuring out how you can combine static analysis + review heuristics to let LLMs course correct the codebase when they over-engineer or produced unwieldy abstractions.

tavakyan: Current project is https:&#x2F;&#x2F;mattera.law which is an inbox-centric matter&#x2F;case management system for law firms.Under the hood it uses a cool legal reasoning agent primarily designed for understanding litigation claims and objectives.Sometimes I do wish I had a slack channel of like 30 attorneys so I can ask them questions and get feedback.

shawntwin: I'm building ai saas web — the simplest way for user and small agencies to try LLM from lab. The problem I kept seeing: site have happy clients but almost no evalution on their site. Asking is awkward, clients say "sure!" and then never give any feedback.

chrisf13: I've been ramping up development of https:&#x2F;&#x2F;whodoyouknowhere.ioIt is a forum application where each community is invite only. Think a cross between reddit&#x2F;discord. The invite only architecture reduces trolls, spam, AI slop and promotes more substantive discussions.Right now invitations are limited to 1 per day for each user in a community. You don't need an invite to join at the global level - but to join any community you must have received an invitation link. Still a major work in progress, right now working on expanding the flexibility of community creation and invitation logic. (allowing bulk invites, adding flexible invitation cool downs, etc).

smusamashah: I have been following you on twitter since I saw it. It looks amazing. Recently tried the demo. It is like under 50MB (the demo at least) which is insane these days. Placing building required construction of the building room by room which was tedious. I am sure some people will enjoy that. Will that be the core part of final game?

socialproof-dev: Interesting pivot — one thing I'd be curious about: does your agency help clients collect social proof &#x2F; testimonials from their customers? That's one of those tasks that sounds simple ("just ask them to write a review") but has terrible follow-through in practice.I'm working on socialproof.dev which automates that step — shareable link, structured form, one-click approve and embed. Wondering if that kind of tool would fit into what a growth agency delivers to clients, or if it's something you'd rather solve with AI prompts and an email sequence.

socialproof-dev: Nice — freelance ops tooling is a real pain point. The rates calculator is a good acquisition hook.One thing I've noticed building in this space: freelancers are remarkably bad at collecting testimonials from clients (who usually love them!). The workflow ends after the invoice is paid and nobody ever goes back to ask for a written review. Worth thinking about whether that's a hook you could add — "invoice sent, client paid → automated ask for a testimonial."I'm building something adjacent to that problem: socialproof.dev. Would be curious what your users say when you ask how they handle testimonials.

pdyc: EasyAnalytica.com It lets you view all your dashboards in one place. Dashboard creation is a 3 step away, point to a file, confirm ds, choose template and done. Supports csv&#x2F;json files, locl&#x2F;remote url, Google sheets and api's with bearer auth.i have also started experimenting with qwen3.5 0.8B model, my goal is to create agents with small models that are as robust as their commercial counterparts for specialized tasks. currently trying it for file editing.

socialproof-dev: I'm building SocialProof (socialproof.dev) — the simplest way for freelancers and small agencies to collect written testimonials from clients.The problem I kept seeing: freelancers have happy clients but almost no testimonials on their site. Asking is awkward, clients say "sure!" and then never write anything.SocialProof gives you one shareable link. Client clicks it, fills a short form (name, text, optional photo), you approve it, it embeds anywhere. No login required for the client.The interesting technical bit: it's entirely on Cloudflare Workers + D1 + Pages. The collection form and embed widget are edge-served globally with no origin server. Been curious whether anyone else is building purely on Cloudflare's stack and what they've run into.Still pre-revenue (just launched today). If you're a freelancer or run a small agency and have thoughts on how you currently handle testimonials, I'd genuinely love to hear it.

kaizenb: Designing a conversational UX for Bookmarker.I was stuck on this conversation problem. First version had a dead-end search box: six starter prompts, one referencing a tool that didn't exist. No follow-ups. No guided flows. Users got an answer and had to invent the next question from scratch.Now the assistant explores your library with you. Tag discovery, color browsing, weekly digests, smart collections that auto-curate as you save.Semantic search runs hybrid, keyword matching plus pgvector cosine similarity on 768-dim embeddings. Streaming responses.Almost there. https:&#x2F;&#x2F;bookmarker.cc&#x2F;

dv35z: (1) PROJECT "AFFIRMATOR" - Start each day out right with chill jazz wake-up music, then life-success wisdom (Earl Nightingale, Tony Robbins, etc). In the evening, fun latin cooking music plays, and then lo-fi chill tunes. At night, your personalized vocalized affirmations & goals plays, and then drift to sleep with meditation music.Tech details: I found that used, small form-factor Dell Optiplexes are great for product protoytyping. I'm in Medellin Colombia, and found that you can buy these for about $200 USD - they are often former Point of Sale (POS) or office computers, from about 10 years ago. They have SSDs, run quiet, and are very reliable.For project Affirmator, I installed Linux Mint Debian Edition (LMDE). Using Cron and Mpv to shuffle-play activity-specific folders of MP3s at the same time each day. For example, for the chill jazz music - I've got a folder of 40+ song MP3s. Cron plays those at 06:30. So it's like a calm, upbeat alarm clock. I'm not a morning person, so this is a "friendly" way for me to wake myself up!For the vocal affirmation part - I built a Python tool that reads 200+ text affirmations from a markdown&#x2F;text file. It then uses AWS Polly text-to-speech API to vocalize the affirmations into MP3s. Next, I use `ffmpeg` to add a variable silent spacer gap to the ends of all the MP3s. This allows your to hear a voice affirmation ("I am fit, athletic, and strong!", "I am a confident piano player."), and then there is silent space for you to say it out loud, or repeat in your head.This project incorporates ideas & routines from: The Strangest Secret by Earl Nightingale, Tony Robbins Personal Power II, Think and Grow Rich by Napoleon Hill, and Atomic Habits by James Clearhttps:&#x2F;&#x2F;codeberg.org&#x2F;jro&#x2F;Affirmator-app(2) PROJECT "LINGOFREQ" - Language learning tool. Uses language-specific high-frequency word lists. Generates example sentences according to a theme&#x2F;topic. Translates the word & example phrases to English &#x2F; Spanish &#x2F; Chinese. Uses Text-to-speech to vocalize the phrases into each language. These phrases are ordered by frequency. When you want to improve your language skills, you set a "window" range of frequency you want to practice, and Lingofreq will play audio files in this range. You can learn Chinese & Spanish while doing the dishes, at the gym, or before going to bed!Code: https:&#x2F;&#x2F;codeberg.org&#x2F;jro&#x2F;LingoFreq-app&#x2F;src&#x2F;branch&#x2F;main&#x2F;apps(3) Medellin COMMUNITY MAKER-SPACE &#x2F; CREATIVE ENTREPRENEUR LAB I'm at Medellin Colombia - my mission is to create the best maker-space. I was a member of ASMBLY Maker-space in Austin Texas (great space!) and worked at Pivotal Labs (agile product prototyping &#x2F; software lab) - so I'm aiming to combine the best ideas from those.BACK-BURNER projects:Documenting my Knowledge as "Public Knowledge Base" - https:&#x2F;&#x2F;codeberg.org&#x2F;jro&#x2F;Knowledge - Here are my notes on Python, Git - I'm bouncing between Obsidian Sync &#x2F; Publish &#x2F; Markdown (currently easiest way), and some sort of open-source knowledge base website (VSCodium + Markdown + FOAM + MkDocs + RClone). I haven't found a solution I'm happy with yet...Open-source CNC router tech stack: - I have a CNC router (robotic drill which can carve 3D shapes into wood). Last year I challenged myself to operate it completely through an open-source tech stack. This took me on a journey of learning Inkscape (2d vector design tool, SVG), FreeCAD (3D product design &#x2F; CAD &#x2F; CAM tool), G-code (format of text instructions which tell CNC tools where to move and what to do), Universal G-Code Sender (a tool which imports CAM - computer aided manufacturing - designs, connects to the CNC router tool, and actually operates machine. It's quite exciting to play with! Used Kiri-moto (web-based CAD &#x2F; CAM tool) to convert 2D&#x2F;SVG designs into 3D shapes). Used OBS (screen recording&#x2F;streaming tool) and a bunch of web-cams to live-stream tool usage to PeerTube Live (similar to YouTube).Being "principled" about using open-source tools can be so challenging, but its quite rewarding on the long run.LEARNING SPANISH - What's working for me... trying to read spanish books before bed. Handwriting a few paragraphs from a book into journal. Highlighting words I don't know. Looking them up later. Reading a book while listening to its audio book at the same time.If anyone's interesting in contributing to these projects, I would warmly welcome that. Design, product, sales, project management, engineering&#x2F;coding, marketing - need tons of help in all these areas.Gracias! &#x2F;&#x2F; JRO

qporest: I finally decided to try and make a note taking tool I've been wanting to use. https:&#x2F;&#x2F;chrononotes.com&#x2F;As many here, I've found that a single text file is all that I really need, but found that it makes it difficult to keep track of a variety of things. I was also trying to use the file as a simple project tracker, adding some tags like [BUG-N], and updating them by hand. Eventually, it became difficult to track the progress of things, since I had to jump around the file to look for updates.. or use grep.I condensed the idea to just that - a very simple tool which manages "trackers", and has a simple filtering built in to "trace" the updates. I've been using it, since I've added the BE, and dogfooding it a bunch. Would love for fellow note takers to take a look. It's not perfect, but I'm keeping it around for myself :)

sunnybeetroot: Does anything similar like this already exist? Ie how do drone shows get planned today?

sunnybeetroot: Hey this looks cool but wanted to highlight a bug. I opened the bot, tapped on sample video and I got the “translating a sample Turkish drama…” message twice. Then it said “your first translation is ready” so I press view in the app and the recent list shows the duplication. It says the first one is ready but the second was in progress. I close the app and see a “our whale friend is gathering video” with a progress bar. So I guess it’s not ready? Then I get a failure message which looks like the second video failed? Anyway, cool idea but it seems buggy and I think the app UX could be simplified, good luck!

cdr1987: https:&#x2F;&#x2F;docules.net&#x2F;aboutI've been building a collaborative docs tool called Docules. The short version: it's a team documentation tool that doesn't have any embedded AI features. I use Claude code daily, but putting LLM’s into every workflow and charging for it is kinda insane. Every docs tool is adding AI auto-complete, AI summaries, "generate a page" buttons. Docules has an open API and ships an MCP server, so it connects to whatever you want to use LLM-wise. They can read, search, create, and edit documents through the API. The core product is just a docs tool that tries to be good at being a docs tool: - Real-time collab with live cursors - Fast — no embedded databases or heavy view abstractions slowing things down - Hierarchical docs, drag-and-drop, semantic search - Comments, version history, public sharing - SSO, RBAC, audit logs, webhooks Stack is React, Hono, PostgreSQL, WebSockets. The MCP server is a separate package so it's not coupled to the main app. I keep seeing docs tools bolt on half-baked AI features and call it innovation. I'd rather build a solid foundation and let you plug in whatever AI workflow actually makes sense for your team. Happy to answer questions about the architecture or the MCP integration.

wishinghand: I got laid off a while ago and I’m privileged enough to take time to reconsider what I want to do. I’ve been learning how to sketch which supports my bigger passion- printmaking. I’ve primarily been doing linocut which is carving negative space into linoleum, inking it up, and printing it on paper. I’ve got a membership at a local atelier and have branched out into drypoint, kitchen lithography, and what I guess is called LEGOpress. I’m sparking a lot of joy working with my hands every day. I have been finding adequate challenge in honing my craft as I try to figure out how to draw&#x2F;carve the images I see in my mind.

celltalk: I have been working on quite a bit of things… but lately I went back to my hobby project of the last year:https:&#x2F;&#x2F;DuoBook.coIt’s like netflix for language, where users can select&#x2F;create their personal bilangual stories.I had quite a lot of feedback from HN, friends, random people on the internet and trying to solve the common pain points and find my way around to make it geniunely useful.- Most people said it’s hard to come up with a story, so I added url grounding. Also added buttons (including HN :)) so people can just click click and get their stories at their level with their interests.- Made sure people can generate stories without ever signing up- Each word is highlighted while being read, and the meanings can be checked with a tap. I also added an option for users to read the sentence for being checked how good their pronounciation is.- Benchmarked 7 different models to get the fastest & highest quality story generation (it’s gemini now) and it’s insanely fast. I might share more about it on the webpage because I am an engineer and I enjoy this stuff lol.- Added CSV import in Use my words so Anki users can just import their words to study.- Also people can download their stories as pdf so they can send it to their kindles.- I am working on a ChatGPT app, so people can just say “@DuoBook give me a Dutch&#x2F;English story on latest Iranian events” within ChatGPT, but I am a bit afraid that it might be costly lol.

WalterBright: Developing the AArch64 code generator for the DMD D compiler.

shevy-java: I am still not working on anything big right now, but among the things I did in the last two weeks or so, I improved the widgets-project I maintain. This one is to be used to support as many different GUI toolkits as possible (including use cases for javascript + the web). The idea is to have objects that are abstract and represent a widget, say: button1 = create_button('Hello world!') button1.on_clicked { the_hello_world_button_was_clicked } # this is the verbose variant in a pseudo-DSL, # I like things being explicit. In most code # I may omit some parts e. g. _ = button('Hello world!') { :the_hello_world_button_was_clicked } It defaults to ruby and what ruby supports (including jruby-swing) but two additional languages to use are python and java. Anyway.I recently added the possibility to describe what kind of widgets are to be used via a yaml file, as an option. This may not sound like a huge win, but so far what I like here is that it becomes easier to modify individual widgets without having to sift through code; and it works for more programming languages too. Any customization for the widget, including method-invocations if necessary, can be done via a yaml file now. There is of course a trade off in that the yaml file can become a bit complex (if the GUI uses many widgets), so for the most part I use this for smaller widgets&#x2F;components that do one specific functionality (or, few specific functionalities). For instance, a GUI over wget. Then if other larger programs need that, I make this small widget more useful and flexible.The distant goal is to actually use a simple DSL that also would allow average Joe to customize everything in a very easy manner; and to have a widget set that can be used for as many different parts possible including wonky ideas such as having a whole operating system as a GUI available one day (a bit like webmin, but not limited to what webmin does; for instance, I'd also have games such as solitaire, reversi and so forth). I'd like to see how far that idea can go, but it is just a hobby so I can only invest little time into it.

Curiositry: I'm publishing 100 blog posts, as part of the #100DaysToOffload challenge: https:&#x2F;&#x2F;www.autodidacts.io&#x2F;tag&#x2F;100daystooffload&#x2F; (started Jan 1, ~55 down, 45 to go)

symkat: I've been working on https:&#x2F;&#x2F;blogdb.org&#x2F; recently.I originally made it a couple of years ago as a small proof of concept. A couple of weeks ago I started it over and have been using it as a project to work with Claude and learn approaches to coding with AI.It's been a lot of fun.

jonasmst: Hey, this sounds like exactly what I've been looking for (household tracking of finances). FYI images are currently not loading on your webpage:)

cdr1987: https:&#x2F;&#x2F;docules.net&#x2F;aboutI've been building a collaborative docs tool called Docules. The short version: it's a team documentation tool that doesn't have any embedded AI features. I use Claude Code daily, but putting LLMs into every workflow and charging for it is kinda insane. Every docs tool is adding AI auto-complete, AI summaries, "generate a page" buttons. Docules has an API and an MCP server instead, so you connect whatever AI tools you actually want to use. The core product focuses on being a fast, solid docs tool. Real-time collab, fast — no embedded databases or heavy view abstractions, hierarchical docs, drag-and-drop, semantic search, comments, version history, public sharing, SSO, RBAC, audit logs, webhooks, etc. The stack is React, Hono, PostgreSQL, WebSockets. The MCP server is a separate package that exposes search, document CRUD, and comments — so Claude&#x2F;ChatGPT can work with your docs without us reimplementing a worse version of what they already do. Happy to talk architecture or the MCP integration.

samirsd: https:&#x2F;&#x2F;www.carnyx.aiMultitrack field recorder with automatic cloud sync for iPhone. I use it for hi-fi recording of band practice and sharing demos with bandmates&#x2F;collaborators. Great way to send stems too as it runs on the Mac as well and has a built in mixer. There's a social graph so you can send someone a session by typing in their handle and granting access.

a_t48: A docker&#x2F;container registry that deduplicates at the file level instead of the layer level. Faster pushes, cheaper storage costs.

MarceColl: Finishing up the last touches to release: https:&#x2F;&#x2F;getkatari.app&#x2F; my japanese immersionnappAlso working on https:&#x2F;&#x2F;www.kinoko.sh&#x2F;. An agentic engineering platform built from the ground up for agents. Custom language and architecture and a later of formal verification on top. Also working on a custom inference engine that produces well typed programs always

stavros: I made my own AI personal assistant:https:&#x2F;&#x2F;github.com&#x2F;skorokithakis&#x2F;stavrobotIt's like OpenClaw but actually secure, without access to secrets, with scoped plugin permissions, isolation, etc. I love it, it's been extremely helpful, and pairs really well with a little hardware voice note device I made:https:&#x2F;&#x2F;www.stavros.io&#x2F;posts&#x2F;i-made-a-voice-note-taker&#x2F;

srivmo: > Stavrobot can message people on your behalf over Signal, Telegram, or WhatsApp. Need to schedule a dinner with a friend? Tell the bot to find a time that works for both of you, and it will message them, negotiate a date, and put it on your calendar.How does the bot message others on Whatsapp? Does the bot need to have a business phone number? Also, do you have a recording of how this looks and feels like?

dataversity: Looks crazy! Thanks for building it, there is indeed a need for a npm or pip like package manager for AI Models.

ciju: The images seem to be loading. They are heavy so might be taking time, or may be something is blocking them?

continuational: I'm working on Firefly, a programming language for full stack webapps:https:&#x2F;&#x2F;www.firefly-lang.org&#x2F;

srivmo: Didnt quite get this - if the only value prop is getting updates straight from the source (trusted&#x2F;vetted journalists), what use is AI here, except for summaries perhaps?

evan_: I’m working on a 2D top-down Zelda-style adventure MMO game. I’m imagining it as a persistent world with Minecraft-like building and procedurally generated quests. I’d like to focus on co-op adventuring and social rather than pvp. Kind of a D&D experience I suppose, though that’s not really a direct inspiration for me.I have no illusions that this is actually something in capable of building to an actual release-able state but it’s fun to tinker with.

MarceColl: This looks perfect, Ill hive ut a go today

heyitssim: I love making games, and I've been building a no-code game engine by extracting reusable components every time I ship a new game. It started as me scratching my own itch, and now it's turning into a real platform.Each game adds more building blocks to the editor: multiplayer, event systems, NPC behaviors, pathfinding, etc. I build a system once, and then anyone using the editor can use it in a click.Since my last month, I shipped the asset marketplace, artists can upload tilesets and characters, and unlike itch.io, assets drop directly into the editor. You can preview how they'll actually look in-game before using them [1].An other problem I kept running into: even with a no-code editor, users don't know where to start. So now I'm extending it with a coding agent. Describe the game you want, and it assembles it — pulling assets from the marketplace, wiring up the event system, and using all the building blocks I've spent the past year extracting. Multiplayer, mobile controls, pathfinding, NPC behaviors — the agent doesn't build any of it, just reaches for what's already there.Once the AI assembles it, users can still jump into the editor and tweak everything [2]. Here's an example of what it can already make [3], and the goal is to reach games like this one I built manually [4].Hoping to release the AI mode in a week or two. The manual editor is live at https:&#x2F;&#x2F;craftmygame.com in the meantime.[1] https:&#x2F;&#x2F;craftmygame.com&#x2F;asset&#x2F;mossy-cavern-JdYWai1[2] https:&#x2F;&#x2F;youtu.be&#x2F;G9Lh4V3SSGI[3] https:&#x2F;&#x2F;youtu.be&#x2F;FZ12XSZu4nM[4] https:&#x2F;&#x2F;craftmygame.com&#x2F;game&#x2F;island-survivor-s1Ay7Go

andsoitis: Do you mind posting these novels?

GalahiSimtam: A solo gamedev project; upgrading my free Skyrim mods; thinking about learning vibe-coding for the little "web 2.0" side-project idea of old, seems could be fun to squeeze it in.

jondwillis: https:&#x2F;&#x2F;getvalara.com - PDF appraisal document in, grounded appraisal review out in 5-10 minutes to aid in risk management for lending institutions and individual appraisal reviewers.We use landing.ai to parse the PDF, as well as useworkflow.dev to durably perform other work such as rendering PDF pages for citations, and coordinating a few lightweight agents and deterministic checks that flag for inconsistencies, rule violations, bias, verify appraiser credentials, etc. etc. Everything is grounded in the input document so it makes it pretty fast and easy. We’re going to market soon and have an approval sign up gate currently. Plenty of new features and more rigorous checks planned to bring us to and exceed parity with competition and human reviewers.There’s plenty of margin for cost and latency versus manual human review, which takes an hour or more and costs $100 or more.

m00dy: https:&#x2F;&#x2F;proxybase.xyz - residential proxies but for agents

jayteedee: I love this. Each time my parents need their wifi fixed I'm going to make them do 5 of this app before it get to work.

OliverGuy: https:&#x2F;&#x2F;gitlab.com&#x2F;usecaliper&#x2F;caliper-python-sdkAn LLM observability SDK that let's you store pre and post request metadata with every call in as lightweight an SDK as possible.Stores to S3 in batched JSON files, so can easily plug into existing tooling like DuckDB for analysis.It's designed to answer questions like; "how do different user tiers of my services rate this two different models and three different systems prompts?". You can capture all the information required to answer this in the SDK and do some queries over the data to get the answers.

ddymke: I am building ReifyDB(reifydb.com), a database for live application state.A lot of existing databases are storage first, with everything else built around them. I have been exploring what it looks like if the database is closer to the application runtime itself, where state is live, queryable, and easier to reason about directly.One thing I am prototyping right now is database-native tests.Basically: what if integration tests were a database primitive?CREATE TEST test::insert { INSERT test::users [{ id: 99, name: "Ghost" }]; FROM test::users | FILTER id == 99 | ASSERT { name == "Ghost" }; };So not a wrapper, not a framework, not an external test runner.A real test object inside the database.The idea is that you could run these before schema changes, and make stored procedures or other database logic much easier to test without leaving the database model.Still early, but it feels like one of those things that should just exist, especially for databases built around live application state.

jayteedee: I made a game where you try to guess a daily mystery bird.http:&#x2F;&#x2F;jerm.cool&#x2F;bird&#x2F;It pulls a list of birds reported on eBird in your county in the last 2 weeks and you ask preselected questions like the the color or size to whittle down the possibilities. I also made a matching game that uses the same list and you have to match the name to a picture of the bird. I set it up for California for now. I wanted to get more comfortable with SQL and APIs.Feedback welcome.

ycombinatornu: GetSize (https:&#x2F;&#x2F;www.getsize.shoes). We’re collecting the official sizing data of the world's shoes in one place.Today, if you search for "what size should I get in Nike Air Max 90" you'll find size charts. We have it, and for 200+ brands across 70+ retailers. When users tell us which shoes they own and what size fits them we’re slowly building crowdsourced fit recommendations which are personal and more accurate compared to size charts.We're two coders who've built an almost fully autonomous platform. AI agents build, debug and deploy crawlers on their own. We went from 4 crawlers to 280+ in about a month, and the whole thing runs on a home server. When new shoes are discovered, the platform publishes new pages with relevant info automatically. Agents get access to platform metrics and SEO data via custom MCPs to identify the right opportunities on their own. Currently at about 3000 MAU and about 100 size recommendations&#x2F;day.Example: https:&#x2F;&#x2F;www.getsize.shoes&#x2F;en&#x2F;shoes&#x2F;nike-air-jordan-1-low-se-...

samename: these are all great ideas!

CubicalOrange: really good idea. I'm curious to know about your datasets that you used for an RE AI.

egglemonsoup: I like the idea and I would play it, but the system of coming up with questions and then having to answer them in order to narrow down the options is unintuitive. Can I see a picture of the bird? Can I hear its call? Can I guess species and see categories get narrowed down? Those aren't necessarily what you need to add, but they're what I'm used to for daily games, and what I expected when I clicked the link.

samename: cool idea!

snncn: https:&#x2F;&#x2F;github.com&#x2F;sinancan34&#x2F;chronomalyChronomaly is a flexible and extensible Python library for time series forecasting and anomaly detection using Google TimesFM.

MrScruff: I’m building an application for documenting modular patches, mostly for my own use case. It uses ML to recognise the patch points, knobs and toggles from a photo of the front panel. You can then build racks from the scanned modules and then store presets of the knobs and connections which are displayed as simple schematics. Idea is ultimately to have it on an iPad as reference to accompany a live performance. Had some fun fine tuning the cable physics engine.

piinecone: When I have time between freelance work I make games and tools for myself.Put One In for Johnny Minn (https:&#x2F;&#x2F;store.steampowered.com&#x2F;app&#x2F;3802120&#x2F;Put_One_In_for_Jo...) - A small soccer game all about scoring nice goals. While I don’t expect it to do well, I’m very happy with how it came out, and it’s the first game I’ve made that I’ll release on Steam! Comes out on Thursday (March 12th).HeartRoutine (https:&#x2F;&#x2F;www.heartroutine.com&#x2F;) - I built this a few months ago to help me stay on top of my heart health. I enter my numbers on the (offline) app, and then configure my goals (like “lower Apo B through diet and exercise”), and then the server emails me every morning asking me what I ate yesterday, how I exercised, etc. The goal is to stay on track, and to be able to bring a cardiologist a very detailed report.

asimovDev: The visuals are stunning, great work!

BozeWolf: Strafter - generate aftermovies from strava activitieshttps:&#x2F;&#x2F;strafter.comDemo fase, showing the branded version to potential clients. We iterate on it with their feedback.

asimovDev: https:&#x2F;&#x2F;github.com&#x2F;AzimovParviz&#x2F;openblaster&#x2F;tree&#x2F;qt6I wrote a CLI utility last year to control my SoundBlasterx G6 DAC (can only control LED colour and EQ bands) without needing to use Creative's windows only program (I am mostly a Mac + occasional Linux) user.Recently downloaded Qwen3-coder-next 80b model and been vibing with it to introduce Qt6 and write a dead simple (aka ugly) crossplatform GUI to it so that other people can use it on their Macs and Linux machines. Letting a LLM wreak havoc on your project feels bad, I constantly have to reign it in and rollback the repo once it starts looping due to writing something that doesn't compile, making it going back and forth between doing and undoing changes.

jedisct1: A tool like Claude Code, Codex, etc. but designed from the beginning to work well with open and local models:https:&#x2F;&#x2F;swival.devIt also comes with nice features and benchmarking abilities. For running evals, it has a companion called Calibra https:&#x2F;&#x2F;calibra.swival.dev

an_am: Screenleash.com: A personal project that deducts money from my bank if I spend more than the allocated time on specific websites. I have already spent around $60, but it has definitely reduced the time I spend playing Smashkarts and on Instagram.Yes, I got addicted to playing Smashkarts (over 2 hours&#x2F;day). Now it is capped at 30 minutes.

soohamr: I inherited a stake in a pyridine derivatives manufacturing factory - while I do not know much about chemical feedstocks and the chemical supply chain, I am trying to help the current partner optimize their yields and reduce losses across multiple stages of reactions across the feedstock and reagents. It is quite similar to hardware design and electrical engineering than I thought.I have also taken an interest in learning distributed paradigms like MPI and am using it on my own cluster of rPis

tomwojcik: Thank you for the kind words. I don't expect it to spread like fire, but I'd appreciate if you could share it with your folks. I don't intend to monetize it, my goal is to have some small daily traffic.It's SFW and localized to the most popular languages.

jayteedee: I like those! A picture of the bird would be the matching game. I want to add a bird song game too. The idea was to make it like the 20 questions game. Maybe I should lean into this more. I did make something where you guess the species and it narrows down through it's taxonomy.http:&#x2F;&#x2F;jerm.cool&#x2F;cafauna&#x2F;It's a bad ripoff of the much, much more fun metazooa (https:&#x2F;&#x2F;metazooa.com&#x2F;play&#x2F;game). I kike it but it gets real annoying when your down to 1 of 10 bats or something. I've been using it to read and edit Wikipedia articles for undeveloped pages.

wonger_: +1 for training parents' tech literacy.I dunno if&#x2F;how this could be taught, but I feel like half the battle is critical thinking with an adversarial mindset towards media -- who would make this, why would they want to show me, do I see anything that makes this impossible, is it worth engaging with in the first place, can I fact check this.

kpmah: Experimenting with operational transforms with https:&#x2F;&#x2F;rootdoc.app

rixed: Still working on my network monitoring tool.Since last time, added a "landing-page" kind of website [0], added annotations with BGP events, support for IPv6, and finishing TLS for every communication between probes and central servers.About to open for beta testers, and still very much interested in comments esp. regarding the UI.[0]: https:&#x2F;&#x2F;www.cloudywithachanceoflatency.net&#x2F;

entropyneur: I am working on a P2P VPN app that lets you use a friend abroad as your VPN provider with no special setup: https:&#x2F;&#x2F;spora.toIt's mainly for censorship evasion (should be much harder to block than the regular centralized VPNs), but also for expats to access geo-blocked domestic services.It's at the MVP stage and honestly it evoked much less interest in people than I hoped it would, but I'm still going on despite my better judgement.

kiru_io: I am working on https:&#x2F;&#x2F;beta.colorguesser.com&#x2F; - a small daily color guessing game.A few years ago it started as colorguesser.com - which is not much maintained, but since there are many new users enjoying this small game, I decide to invest more time and add more feature.

yuppiepuppie: Keep on chugging away at The HN Arcade :) https:&#x2F;&#x2F;hnarcade.comOver the past weeks, we consistently get 5-6 submissions per week. The newsletter and number of visitors are growing.I’ve come to treat this as a pet project but realized that for indie devs who get very little marketing attention, being featured in the newsletter, top of the daily list, etc. can be another burst of users.

militanz: I'm working on a hobby project named Belisarius that allows you to manage multiple repositories simultaneously by executing common commands and operations.https:&#x2F;&#x2F;codeberg.org&#x2F;alelavelli&#x2F;belisarius

abrolaryan: i was delighted to see your comment at top... I am working on the exact same thing, generating concept DAGs from books and letting a tutor agent use it for structure and textbook reference. can we discuss this somewhere else?

auggierose: That is interesting. Do you have a paper &#x2F; book or anything like that which explains your work?

SunboX: https:&#x2F;&#x2F;eggbot.app&#x2F; an app for the widely OpenSource available EggBots to draw easter eggs. :)

aleda145: Still working on https:&#x2F;&#x2F;kavla.devI have worked with data for a while. I feel like our tools could be much better when it comes to "flow". I want an experience where you don't need to alt+tab to slack&#x2F;images&#x2F;another query. What if we put it all on a canvas? That's what Kavla is all about!Since last month I've done a lot of improvements to the editor to make the "flow" better.I've also read up on HMAC, Nonces and fun encryption stuff to create read only boards.Here's one where I look at stack overflow survey for databases: https:&#x2F;&#x2F;app.kavla.dev&#x2F;v&#x2F;mqhg54o319doya4.67dbfee1ccd6caf638d3...Snowflake users apparently make the most money!

GiorgosGennaris: Building an AI graphic designer that takes you text and converts into a finished design based on your choosen size, style and branding.Currently optimized for restaurant menus but maybe we should expand to other type of long-form materials like brochures and infographics.https:&#x2F;&#x2F;correctify.com.cy&#x2F;

rozenmd: I've been celebrating five years of working on OnlineOrNot (https:&#x2F;&#x2F;onlineornot.com&#x2F;) by adding more features for teams that build software:- 2FA, PassKey, and password-based login for folks that hate magic links- Moved my entire API from GraphQL to REST so I can fully dogfood the API I offer- Added an audit log as standard on all plans- Built a terraform provider (https:&#x2F;&#x2F;github.com&#x2F;OnlineOrNot&#x2F;terraform-provider-onlineorno...), and a way to download existing config into terraform files- Started iterating on a CLI (https:&#x2F;&#x2F;github.com&#x2F;OnlineOrNot&#x2F;onlineornot)

merelysounds: Nonograms! I built Nonodle[1], a daily nonogram puzzle game and I’m adding an option to access these puzzles from Nonoverse[2], my iOS nonogram app.There is an API, and it’s a straightforward task, but one thing led to another and I’m also improving the app UI. I still hope to have the update soon.[1]: https:&#x2F;&#x2F;lab174.com&#x2F;nonodle&#x2F;[2]: https:&#x2F;&#x2F;apps.apple.com&#x2F;app&#x2F;nonoverse-nonogram-puzzles&#x2F;id6748...

davidcann: Native macOS sandbox terminal:- UI for sandbox-exec to protect filesystem - Network sandbox per domain - Secrets filter via gitleaks - Vertical tabs optionIt's highly customizable. You generate native macOS app wrappers for each terminal app, each with its own rules and customizations.https:&#x2F;&#x2F;multitui.com

tomwojcik: Yep, my thoughts exactly. But the consumer rarely thinks critically when looking at ads, not to mention regular social media posts and the Big Corp has no money in proving what assets are AI generated.I'm trying to gamify the training to make the experience more appealing.I store a "proof URL" on the backend, but I don't know if it makes sense to serve it to the end user. Also, a Reddit discussion is not necessarily a proof one wants. A fingerprint would be better, but not all images are generated with Google. That's another problem to be solved.

s-macke: To reverse engineer old C64 games using Coding Agents, I built a CLI and MCP flow disassembly tool. The agent can search the disassembly, provide annotations, manage symbols, and reinterpret code and data.[0] https:&#x2F;&#x2F;github.com&#x2F;s-macke&#x2F;OpcodeOracle

ekrapivin: https:&#x2F;&#x2F;inSolitaire.comI'm enjoying building solitaire and puzzle games.My goal is to make this project the largest online collection of free modern solitaire games available for all kinds of devices.

dataviz1000: Interesting. I'm not familiar with ClickHouse. I've been manually triggering compression and continuous aggregates have been a huge boon. The database has been the least of my concerns. Can you tell me more about it?

gregleon: You can take a look at this: https:&#x2F;&#x2F;github.com&#x2F;ClickHouse&#x2F;stockhouse The database schema is optimised for stock data

aix1: This looks cool, but what I'd really like is a self-hosted pipeline that I could use to auto-subtitle videos I already have locally. This would help my language learning a great deal.If any of you have already figured out a tool&#x2F;workflow for this, I'd love to learn from your experience.

foo42: Sounds fun. Can't beat a good whimsical project!

hasukimchi: I am working on two small apps for my dungeons & dragons group. We're playing inperson and I really like to give them printed out cards for magic items they receive and also for spells, because they are quite new to the game.So I build these two app to create items and spell cards and print them out.https:&#x2F;&#x2F;www.item-forge.org&#x2F;https:&#x2F;&#x2F;www.spell-forge.org&#x2F;

tschmits: "Ride in Review" looks great! Great concept, perfect demo. I hope you guys find a client: this deserves the next phase.

Mackser: Cakedesk: Fast & simple invoicing app for small businesses (Windows & Mac).Been working on this for about 4 years. It has some cool features, like letting you create your own PDF templates with HTML&#x2F;CSS. Most users love that it's so simple and just a one-time purchase.Currently thinking about how to implement an Obsidian-style cloud sync feature since that gets requested a lot.https:&#x2F;&#x2F;cakedesk.app

nottorp: I'm never clear if this Ask HN is for posting about what you're messing with or for promoting organized projects that chase github stars or are commercial.But anyway, I've started to learn Go. By doing a vertical scrolling shooter with embiten. Kinda like fitting a square peg into a round hole. No, it's not public and will probably never be.Studying how do do a memory pool for actors, since it doesn't look like garbage collection and hundreds of short lived bullet objects will mix well.

rick1290: seems interesting. whos the target demo for this though?

natedaines: I was exploring a spec development system (similar to the likes of openspec) but with specifications that are more succinct. One of my frustration with openspec is the number of files that are generated from the proposal, to the design and implementation.https:&#x2F;&#x2F;tinyspec.dev&#x2F;

ongedierte: I’ve been messing around with a similar project (but in a grimdark&#x2F;cosmic horror setting). I was running into the same issue, agents getting stuck in a loop. What worked for me was adding dwarf fortress&#x2F;rimworld like systems. The random events and systems influencing systems worked wonders for me.

mx7b7: I'm working on a cross‑platform snippet manager & local code runner built with Avalonia: https:&#x2F;&#x2F;github.com&#x2F;mx7b7&#x2F;codesnip-avalonia

domh: Hey! The demo didn't work in Firefox. It said something about setting up the database then it crashed the tab.

robalni: I just started building an operating system that will be written entirely in one text file. This text file includes in order: a readme, a RISC-V assembly boot code, then the rest. You run it by compiling the initial boot code with a RISC-V assembler, then you concatenate the binary with the whole text file itself. Then when you run it, the boot code will compile the rest of the text file (the operating system), including higher level language compilers that the rest of the system will be written in.This is the kind of project that creates something from as little as possible, where the only things you need to get started are a very basic RISC-V assembler and a computer or emulator to run it on.I don't have anything interesting to show yet because I just started yesterday, but one day I will show you.

woutgaze: Is it also self-hosting as a sort of meta-quine?

sarthaksaxena: Yeah :)! Just run `llmpm init` to start packaging your models along with your code.

radva42: I am working on a HTML-to-PDF converter written from scratch in pure Go. I got tired of using headless browsers for various reasons and decided to give it a try and implement something that I can use internally. However the results have far exceed my expectations and I've decided to open source everything. It's around 10x to 15x faster than wkhtmltopdf, which is by far the fastest headless browser converter. It's 80x-100x faster than a pagedjs. It's even 2x faster than PrinceXML, which is pretty much the most mature and reliable HTML-to-PDF converter on the market. It also produces the smallest PDF size.I started small as a toy project, but gradually implemented full support for proper block context, flexbox layout, CSS variables, tables, etc. to the point where I have almost full support of all major CSS features (even math functions like calc(), min(), max()).I'm cleaning up the code right now and will upload it later today or maybe tomorrow here: https:&#x2F;&#x2F;github.com&#x2F;PureGoPDF

0xAX: Working on update of linux-insides (https:&#x2F;&#x2F;github.com&#x2F;0xAX&#x2F;linux-insides) adapting it for modern kernels versions

levmiseri: A webapp combining note taking with messaging. Recently added a new feature that allows for creating communities in a lightweight discord-like UI:https:&#x2F;&#x2F;kraa.io&#x2F;kraa&#x2F;trees

iknowstuff: So pretty. But:> Both adults in a family will now own a car. This is required since there are not other transportation options, and sidewalks are optional.Is this temporary or are you planning to release it like this? SimCity leaned into euclidean zoning (separate industrial&#x2F;residential&#x2F;commercial zones) and pocketable cars which needed no parking, and thus failed to properly showcase how ugly car-centric cities actually are. I’m sure they did it because it made for an easy gameplay loop&#x2F;balancing but I’d hope we could come up with more realistic and interesting mechanics in 2026

sersi: I actually would really love that in a city planner. A game that actually simulates walkable cities versus car centric abominations and would adapt families strategies based on the availability of sidewalks, public transports and incentives.

lebuin: I'm building web-based CAD software for woodworkers. Not a plugin, I'm starting from scratch. I'm aiming for it to be intuitive for non-technical users (think SketchUp), while also offering some of the more powerful tools of "proper" CAD tailored for woodworking: simple parametric workflows, cutting layout optimization, built-in tools like chamfers and joints,...https:&#x2F;&#x2F;maqet.app

snncn: A campaign management tool for automated contact form outreach. It helps users manage websites, detect contact pages and forms, and fill them automatically using LLM-powered field matching.

dovudhusan: I'm building postaxis.io - it helps builders to distribute their own apps&#x2F;products

benterix: You said "vibecoded", maybe it triggered someone. I upvoted you as I just learned YouTrack exists, and it has 10-users free plan, I'm going to give it a try,

gerlv: Building DynoWizard [1] - tool for designing single table DynamoDB tables.I first used DynamoDB 8 years ago and have been designing single-table schemas heavily since. For me, the best way to create drafts was always pen and paper (and then excel&#x2F;confluence tables), but in reality it's a process (based on The DynamoDB Book) that can be automated to an extent.Decided to build an app while on paternity leave. You define entities and access patterns, create (or get suggested) key and GSI design, and generate code for access patterns (TypeScript and Python), infrastructure (CDK, CloudFormation, Terraform), and documentation you can share with stakeholders.There's more I want to build beyond the MVP - things around understanding and validating designs that you can't get from a chatbot - but for now focusing on the core.If anyone wants to try it out, sign up for the waitlist on the landing page. MVP should be ready in the next few weeks.[1] https:&#x2F;&#x2F;www.dynowizard.com

cloudhead: I’m working on Radiant Computer: https:&#x2F;&#x2F;radiant.computer — a new from-scratch personal computer and OS.

ponyous: 3D AI Modeling software intended for 3D printers.https:&#x2F;&#x2F;grandpacad.comOriginally I made it for my grandpa, but I got a lot of interest so I made it into a full commercial product.Just yesterday I published a set of 3 mini tutorials if you want to see how it works - https:&#x2F;&#x2F;youtube.com&#x2F;playlist?list=PLKt1F5TvOjAHE07oBDlPXcrHc...

SamDc73: yeah sure, my email is in the bio

dataversity: Also, is there is way I can invoke these models or is there an API which your tool exposes?

absqueued: [delayed]

hirako2000: Rebuilding iNaturalist with open source&#x2F;weights models that can run on edge compute for better privacy, and hopefully accuracy.

didmar8312: Building ConvoLens [1] - app to explore the content of video interviews from YouTube channels I like (such as Dwarkesh Patel's): research by keyword, RAG, visualization of discussed topics with a 2D projection, semantic graph, and the possibility to generate a new video or audio from a playlist of video segments.Supports only YouTube as the data source, and Gemini 3.1 Flash Lite for processing, but it can easily be tweaked. Runs locally with Docker compose.[1] https:&#x2F;&#x2F;github.com&#x2F;didmar&#x2F;convolens

ycosynot: Nobody will read this and the game is not ready, BUT maybe one of you can check it out and tell me what you think. It is called ZAEL. It is a mage arena web app (smartphone&#x2F;Desktop), played from 1 to 4 players, no login, easy to share a link to invite people into your game, whatever the platform. It is no install, no bullshit. Just click and playhttps:&#x2F;&#x2F;www.zael.appI have found out that it is very efficient to use phaser.js&#x2F;three.js for fast, vibe coding, because it handles everything without having to setup a unity scene manually or unreal blueprint. I really recommend to make web apps instead for vibe coding. I love how easy it goes.

mog_dev: I built Collider, A wrap-based package and dependency manager for Meson.I needed a way to use and push my own artifacts in Meson projects. WrapDB is fine for upstream deps, but I wanted to publish my packages and depend on them with proper versioning and a lockfile, without hand-editing wrap files.Collider builds on Meson’s wrap system: you declare deps in collider.json, run collider lock for reproducible installs, and push your projects as wraps to a local or HTTP repo. It’s compatible with WrapDB, so existing workflows still work: you just get a clear way to use and push your own stuff. Apache-2.0.https:&#x2F;&#x2F;collider.ee

EmanuelB: I am working on Kastanj. It aims to make cooking as foolproof as it can get. Anyone should be able to cook any recipe and get it right on the first try. Clear step by step images and instructions for everything etc.It also features a recipe manager with family&#x2F;friends sync. This makes it possible to upload your grandmother’s cookbook and share them with your whole family.https:&#x2F;&#x2F;kastanj.ch&#x2F;

ciju: It doesn't work in Incognito mode. Did you try it without incognito?

mconnell: I'm building https:&#x2F;&#x2F;preflight.qa, an opinionated take on Email QA for developers and marketing teams.

junaid_97: I'm building Fillvisa: Turboxtax for Immigration [1]It's a free USCIS form-filling web-app(no Adobe required). USCIS forms still use XFA PDFs, which don’t let you edit in most browsers. Even with Adobe, fields break, and getting the signature is hard.So I converted the PDF form into modern, browser-friendly web forms - and kept every field 1:1 with the original. You fill the form, submit it, and get the official USCIS PDF filled.I found out SimpleCitizen(YC S16) offers a DIY plan for $529 [2]So, a free (and local-only) version might be a good alternative[1] https:&#x2F;&#x2F;fillvisa.com&#x2F;demo [2] https:&#x2F;&#x2F;www.simplecitizen.com&#x2F;pricing&#x2F;

functional_dev: Building a cheaper alternative to Twilio Voice Intelligence. Record phone calls, transcribe, generate AI summaries, enable semantic search over transcripts — $0.30&#x2F;hour vs Twilio's $1.50&#x2F;hour.Stack is 15+ Go microservices on k3s. Cross-lingual semantic search is fun. Spanish query returns English calls with no translation code.https:&#x2F;&#x2F;audiotext.live&#x2F;

storystarling: StoryStarling. You describe a story idea and it generates a fully illustrated children's book, then we print and ship it.Not templates with names swapped in. Every story and illustration is made from scratch. You can go from "dinosaurs soccer" or write out a whole storyline. Pick an art style, optionally upload reference photos of your kid, and it builds a 28 page book in a few minutes.Bilingual in 38 languages. We handle RTL (Arabic, Hebrew), CJK, and less common languages like Estonian, Maltese, Irish where there's not much available for kids.Tech side for the curious: LangGraph orchestrates the pipeline, Celery workers do image generation and text rendering in parallel, and LLMs critique the illustrations for consistency mistakes and can trigger regenerations automatically.Printed in Germany, booklet around 20 EUR, hardcover around 40 EUR.https:&#x2F;&#x2F;storystarling.com

fainpul: Blender is not the right tool for that. I think you'll be happier with an actual CAD tool like Fusion or FreeCAD.

kkarpkkarp: I’m working on WC Price Hostory, a plugin that handles price tracking and Omnibus Directive compliance for WooCommerce.It’s been available as a free tool for years, growing to over 45k active installs. I just rolled out the Pro extension to offer more advanced features, and the early traction has exceeded my expectations. If you're running e-commerce in Europe, this is a must-have for staying compliant with EU law.https:&#x2F;&#x2F;wcpricehistory.com&#x2F;

thom: Do you intend to one day support all the paged media bits in pagedjs? I assume it works with their polyfill but it’d be great to have a built in more performant option.

RamblingCTO: I just launched bookcall.io publicly last week. Think calendly that treats your scheduling page more like a sales funnel. Very important if one call can make you a bunch of money. Page builder, brand assets, videos, documents etc. attachable. Forms, video calls, everything included.Also launching a supabase security scanner. If someone wants a free scan hit me up. Includes POCs and verification before and after remidiation. Goodbye false positives.

ph4rsikal: Why do you work on this when Claude Cowork for Finance exists>

audessuscest: > PureGoPDF doesn't have any public repositories yet.

thr0w4w4y1337: I've built a generic PKCS#11 interface to the Apple's Secure Enclave[1]Primarily to use in conjunction with OpenVPN. Like secretive or &#x2F;usr&#x2F;lib&#x2F;ssh-keychain.dylib[2], but not just for SSH.1 - https:&#x2F;&#x2F;github.com&#x2F;ne-bknn&#x2F;nailed2 - https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=46025721

sarthaksaxena: Yes indeed there is, run `llmpm serve <model_name>`, which will expose an API endpoint http:&#x2F;&#x2F;localhost:8080&#x2F;v1&#x2F;chat&#x2F;completions & also host a chat UI where you can interact with the local running model https:&#x2F;&#x2F;localhost:8080&#x2F;chat.Follow the docs here: https:&#x2F;&#x2F;www.llmpm.co&#x2F;docsPro tip for your use case: Checkout the `llmpm serve` section

wastewastewaste: I somewhat like it for what it is, but expected something else based on description. This is just a real&#x2F;ai guesser that doesn't really train you at all.

kkarpkkarp: NotifyButton - A simple script on the frontend of your site, a complete SaaS platform on the backend for DSA compliance.If you operate in the EU and want to avoid heavy fines, this is for you. Once integrated, it allows users to report legal content issues directly to you, which you can then manage via a dedicated dashboard following official EU procedures. Without such a system, users are much more likely to file complaints through official state or EU channels, which can trigger investigations.https:&#x2F;&#x2F;notifybutton.com&#x2F;

mchaver: I really like https:&#x2F;&#x2F;math.growingswe.com nice job! I did the foundations page. I will work through some more lessons and give you some feedback later this week. I am also working on some math projects. Take a look at my other comment in this Ask HN.

nhatcher: Well, I just jumped full time on IronCalc[1] a fully open source, light and fast spreadsheet engine designed and build from the ground up.I have been working on it as side project for over two years and now, with funding from the EU for the next 2.5 years, I hope I can make of it a real product for everyone to use that can compete with the likes of Excel and Googl;e Sheets.I can oly say, I am overly, off the Moon excited[1]: https:&#x2F;&#x2F;www.ironcalc.com

FattiMei: Interesting, how was the EU funding process?

socketcluster: A no-code platform for building SaaS apps with AI (serverless): https:&#x2F;&#x2F;saasufy.com&#x2F;

mchaver: I am working on some math education tools. One is free and open-source, the other is paid.Free Math Sheets is a tool to generate math worksheet PDFs (and the answer keys if required). Currently it supports K-5 but I want to expand it to higher levels of math (Calculus, Physics, you name it!). You select a bunch of different options and then generate it. All in the front-end. No back-end or login in required. https:&#x2F;&#x2F;www.freemathsheets.comIf you are interested in helping out or forking it, here is the github repo github.com&#x2F;sophikos&#x2F;free-math-sheetsThe paid project is Numerikos. I am going for something in between Khan Academy and Math Academy. I like the playfulness and answer input methods from Khan Academy (but it is linear, doesn't have a good way to go back and practice, etc.). I like Math Academy's algorithm (but it has multiple choice answers, yuck! and is easy to get stuck and doesn't have a good way to explore on your own). Currently Numerikos supports 4th and 5th grade math lessons and practice. The algorithm is based on mastery learning like Numerikos, but you can also see a list of all the skills and practice whatever you want. I am also working on a dashboard system where you can build your own daily&#x2F;weekly practices for the skills you care about. Next up is 6th grade math and placement tests.https:&#x2F;&#x2F;www.numerikos.com&#x2F;

zufallsheld: > I'm cleaning up the code right now and will upload it later today or maybe tomorrow here

arnorhs: Which EU grant did you receive? Ie. from which fund?

LukeB42: In the past couple of months I'veBuilt a Cythonized Icecast2 implementation I've wanted for years: https:&#x2F;&#x2F;github.com&#x2F;lukeb42&#x2F;cycastBuilt a p2p Kanban board that fits in a single .html file and uses only the Python stdlib for LAN discovery https:&#x2F;&#x2F;github.com&#x2F;lukeb42&#x2F;kanban_p2pDeveloped a p2p legislature that scales from a small team of 3 users to countries of tens of millions of people: https:&#x2F;&#x2F;gist.githubusercontent.com&#x2F;LukeB42&#x2F;deb887691f13dee9c...Developed a small SPA framework inspired by React, Ractive-Load and hn.js: https:&#x2F;&#x2F;lukeb42.github.io&#x2F;vertex-manual.htmlUpdated a news archival service for Python 3.x: https:&#x2F;&#x2F;github.com&#x2F;lukeb42&#x2F;harvestMade a scriptable IRC client inspired by irssi and mIRC: https:&#x2F;&#x2F;github.com&#x2F;lukeb42&#x2F;scrolland worked on a couple of my company's products.

marak830: Oh that Live Kaiwa looks interesting, I might try it out this weekend with my wife and son (native Japanese). Anything to help my admittedly horrible Japanese

diasks2: Shoot me an email (diasks2 at gmail.com) and I’ll whitelist your email for some free usage credits. Would love to get feedback.

hedayet: "Does a launch make any impact if there's no audience?"We've found most early-stage startups ignore social media until after a launch. Things like “$0 spent on ads” sound cool, but they don’t help if no one knows your product exists.I'm building Appents to provide a done-for-you social media solution for startups.Would love feedback: https:&#x2F;&#x2F;appents.com&#x2F;

mchaver: I took a look at it because you do PDF generation (I am doing front-end PDF generation in my project as well so I wanted to compare), not because I know anything about knitting or crocheting. I made a design, drew on the grid a bit, but was unable to export. I am not sure if I was missing something but it would be helpful to the user if there was a message in the export area about why they cannot export yet.

zelphirkalt: Tricky! I often also guess wrong. But I noticed it has some bug. Sometimes I can click either option "AI Generated" or "Real" and nothing happens. Even if I click 10 times, still nothing happens. The buttons must have some broken event handling or something.EDIT: Hm, I switched tab, away to write this comment, now that I switched back, it showed me that I clicked correctly. So it seems, that sometimes it just has huge delay in accepting my choice?

maxharrison: Been recently playing around with using LLMs and the promise of malleable software.Published a demo&#x2F;experiment under MalleableTodo [1] - and so far seen some pretty strange use cases...Essentially, just allows each user to use an LLM to rewrite their own UI to add features&#x2F;customisation.[1] https:&#x2F;&#x2F;malleabletodo.app&#x2F;

nhatcher: First we got a grant from the NLnet[1], which I highly recommend as a first step of any project. Single best thing I could have done. That wasn't enough money for me to quit my job. Also I didn't have any _evidence_ that IronCalc was a good idea or that there was a market for it. Then evidence started pouring and I kept working. I started talking to different folks, lots of people many of those were contacts through the NLnet. Then the folks from NextGraph[2] approached us and asked, "Hey do you want to be part of this consortium [3]?". Eventually we got a HORIZON grant after a lot of sweat and paperwork, but NextGraph took the brunt of it.As you see there is a huge component of sheer luck[1]: https:&#x2F;&#x2F;nlnet.nl&#x2F;project&#x2F;IronCalc&#x2F; [2]: https:&#x2F;&#x2F;nextgraph.org&#x2F; [3]: https:&#x2F;&#x2F;elfaconsortium.eu&#x2F;

high_priest: This looks great if combined with versioning system. As part of git repor for example. But, for general journaling, I would not trust something that does not leverage the strengths of a filesystem.

JoyboyPeak: I'm learning bug bounty hunting again. And thinking to start opensource contribution

JoyboyPeak: I'm learning bug bounty hunting again. learn to contribute to NUCLEI open source contribution.

tomwojcik: The project got some traction, over 5k requests since I posted this. Probably the DB state needs to be optimized a bit. Thank you for reporting! I really appreciate itEdit: I don't see slow traces in Sentry. No idea what caused this. Also, voting goes through redis and the dB load is low. Weird. I probably have to add gunicorn workers.

stereobit: A lightweight framework on top of Temporal for building reliable, stateful AI agents on top of temporal.Think OpenClaw, but durable, with long-term state, and enterprise-ready. We've been using it internally to build agents for a while now and have decided to open-source it.https:&#x2F;&#x2F;github.com&#x2F;bead-ai&#x2F;zeitlich

PAndreew: Managed BYOK stateless agent orchestrator called BeeZee: https:&#x2F;&#x2F;beezyai.net&#x2F;. Basically Claude Cowork &#x2F; a coding agent on the web but provider agnostic, you own the data and you can connect several nodes to it. Instead of installing an agent for all your machines you have one master agentic server and executor nodes. The server is stateless the data lives on the nodes and in a managed database. I use Supabase and Google KMS so my auth keys are encrypted. Uses Pi agent under the hood. This enables me to code from my phone without a dedicated SSH terminal and without the need to babysit the agent. I describe the feature, off it goes, I close my phone and in 10 mins the results are there. Also using it to support my wife with white collar stuff like Excel analysis, translation, etc. It's a bit buggy but getting better.

aix1: And how is it going, in terms of finding those limit? It would be very interesting to hear about areas where the actual experience turned out to be wildly different from your expectations, in either direction.

tacone: I am creating AI coding framework (a set of skills and scripts, really), since it seems a lot of them don't support copilot.I don't think what I am doing is really original, but it's shaping nicely.I am working on:- feature folders (one folder per feature, with changelog, issues, summaries etc)- coworkers (cli-agents, with session management)- agents intra-response messagingIn general the goal is forcing Claude to behave, which is quite ambitious :).

fjeibcjend: working on researching how much the impact of media and ad network requests is on web sites

jjude: We have been homeschooling our kids. Homeschooling in India is not that widespread. So when a national newspaper covered our experiment, I got lot of questions around what we were doing. For a while I wrote blog posts answering them.Now I've written quite a few posts (and given talks), I thought of writing a book. Just wrote two chapters. The draft lives here: https:&#x2F;&#x2F;www.jjude.com&#x2F;books&#x2F;hs&#x2F;

aix1: This thread prompted me to look into this and it seems all I need is a thin wrapper around whisper-ctranslate2. So I wrote one and am playing with it right now. Thanks for the idea.

tonyedgecombe: [delayed]

warangal: VITS is such a cool model (and paper), fast, minimal, trainable. Meta took it to extreme for about 1000 languges.It seems like you have been working on this application for sometime, i will go through your code , but could you provide some context about upgradations&#x2F;changes you have made, or some post describing your efforts.Cool nonetheless!

otsaloma: Trying out vibe-coding (so mostly not even reading the code) a note-taking web app that's essentially a simplified and dirt-cheap to host Workflowy clone. That seems to me like an easily disruptible SaaS in the sense that note-taking is a very generic app, I only use a small part of the feature set of Workflowy and find the price far too high given that. A lot of other vibe-coding around me I see is throw-away junk, but my intention is to actually use this. The frontend is mostly done and working quite nicely already. Sync is then more crucial to get right to avoid data loss and I think I'll review and rewrite myself more of that.

aquariusDue: I've joined this year's Flame Game Jam which uses the Flame Engine built on top of Flutter. This is my first game jam and I really hope I manage to submit the game before the deadline on Sunday.Here's a link to the jam if anyone else is interested, and I recommend joining the Discord server too because the organizers and participants are really great and fun to hang around! - https:&#x2F;&#x2F;itch.io&#x2F;jam&#x2F;flame-game-jam-2026

StanAngeloff: I've been working on an AI workspace inside Neovim (and using the editor as the TUI). When I started, I asked myself, "Wait, WHAT?! Another one? Who would use this?" However the goal was never about eyes (well, GH stars) on this new thing, it was about learning. I wanted to dig deeper into how modern-day tools work so I can understand the sort of 'magic' I was experiencing using tools like Claude Code. The more I've been working on this side project, the more I understand about AI systems, agent loops, prompt engineering and all the cleverness that goes into making a good, usable, magical AI agent.

XCSme: Started on making my own AI model benchmarks and leaderboard[0], after I tested MiniMax M2.5, which was supposedly good based on standard benchmarks, but peformed really poorly in practice and burned through hundreds of thousands of reasoning tokens for each request...[0]: https:&#x2F;&#x2F;aibenchy.com

kindkang2024: My 8-year-old is learning English and loves Peppa Pig. I thought — what if he could actually pick up words from watching it? Not "tap the apple" drills, but learning from the show he already loves.So I built YouLingua (https:&#x2F;&#x2F;youlingua.world). Paste any YouTube video and get a word-by-word interactive transcript. Click a word to save it with the exact video moment — "muddy puddles" isn't a flashcard, it's Peppa jumping in one. Saved words then power mini-games: a space shooter, hex puzzles, TikTok-style review shorts...Browser-based, no install. Login with a Web3 wallet — no grand reason yet, just something I'm interested in. Dream is to eventually make it fully decentralized so you truly own your learning data.Still early, but my son now asks to "play the word game." That feels like a win.

arvida: Been working on https:&#x2F;&#x2F;localhero.ai, its my service to automate on-brand translations for product teams. I've been doing outreach to Swedish companies&#x2F;people, getting some good interest from a few that want to automate their localization workflow but don't want the work of maintaining own solutions. Even though you can build a version working with coding agents these days, there is a lot of stuff around it to make it work well over time in a product org. On the tech side for Localhero, one thing I've been working on how it learns from manual edits. Like when a PM or designer tweaks copy in the Localhero UI, those things now better feed back into a translation memory and influence future translations. It's like a self-learning loop, turns out a pretty nice combo of using old-school techniques and offloading some work to LLMs.Also been spending some time on my old side project https:&#x2F;&#x2F;infrabase.ai, an directory of AI infra related tools. Redesigned the landscape page (https:&#x2F;&#x2F;infrabase.ai&#x2F;landscape), going through product submissions and content, optimizing a bit for seo&#x2F;geo.

linayang210: Hi, garry. I hope you’re doing well. I wanted to briefly introduce myself.I’m a Senior Full Stack Engineer with over 8 years of experience building and scaling production systems using Node.js, TypeScript, React, and Python. I’ve worked in remote, product-focused environments where I’ve led architectural improvements, including migrating a monolithic system to microservices, reducing deployment time by around 50% and improving scalability and reliability.I’m comfortable owning features end-to-end — from system design and API development to deployment, performance optimization, and production support. I’ve also implemented CI&#x2F;CD pipelines, improved database performance (PostgreSQL), and contributed to cloud-native infrastructure on AWS using Docker and Kubernetes. In addition, I’ve worked on AI-driven workflows and LLM integrations for modern product capabilities.I’m currently exploring new remote opportunities and would love to connect if you’re building or scaling a product where strong backend architecture, clean execution, and ownership matter.If it makes sense, I’d be happy to schedule a short conversation. Thank you.

tskulbru: Following up the comment i made last month, I'm a solo dev building a handful of apps across different niches.- Plask ( https:&#x2F;&#x2F;plask.dev ) — Google Analytics (GA4) connected analytics dashboard for people who ship multiple products. I got tired of manually checking separate GA4 properties for all my apps and SaaS projects, and setting up individual MCP integrations for each felt like overkill when I just wanted a quick overview. So I built a single dashboard that connects all your GA4 properties, runs statistical anomaly detection, sends alerts when something breaks, and generates AI weekly digests. Free tier for 2 properties, Pro at $9&#x2F;mo.- Kvile ( https:&#x2F;&#x2F;kvile.app ) — A lightweight desktop HTTP client built with Rust + Tauri. Native .http file support (JetBrains&#x2F;VS Code&#x2F;Kulala compatible), Monaco editor, JS pre&#x2F;post scripts, SQLite-backed history. Sub-second startup. MIT licensed, no cloud, your requests stay on your machine. Think Postman without the bloat and login walls.- APIDrift ( https:&#x2F;&#x2F;apidrift.dev ) — Monitors changelogs for APIs, SDKs, and libraries you depend on so you don't get blindsided by upstream breaking changes. Scrapes docs, diffs changes, classifies severity with AI, and sends digest emails. Track your dependencies, get alerted when something breaks. Free tier covers 3 sources with weekly digests. Built with Next.js, Supabase, and Gemini Flash.- Mockingjay ( https:&#x2F;&#x2F;apps.apple.com&#x2F;app&#x2F;id6758616261 ) — iOS app that records video and streams AES-256-GCM encrypted chunks to your Google Drive in real-time. By the time someone takes your phone, the footage is already safe in the cloud. Built for journalists, activists, and anyone who needs tamper-proof evidence. Features a duress PIN that wipes local keys while preserving cloud backups, and a fake sleep mode that makes the phone look powered off during recording.- Stao ( https:&#x2F;&#x2F;stao.app ) — A simple sit&#x2F;stand reminder for standing desk users. Runs in the system tray, tracks your streaks, zero setup. Available on macOS, Windows, Linux, iOS, and Android.- MyVisualRoutine ( https:&#x2F;&#x2F;myvisualroutine.com ) — This one is personal. I have three kids, two with severe disabilities. Visual schedules (laminated cards, velcro boards) are a lifeline for non-verbal children, but they're a nightmare to manage and they don't leave the house. So I built an app that lets you create a full visual routine in about 20 seconds and take it anywhere. Choice boards, First&#x2F;Then boards, day plans, 50+ preloaded activities, works fully offline. Free tier is genuinely usable. Available on iOS and Android.- Linetris ( https:&#x2F;&#x2F;apps.apple.com&#x2F;app&#x2F;id6759858457 ), a daily puzzle game where you fill an 8x8 grid with Tetris-like pieces to clear lines. Think Wordle meets Tetris. Daily challenges, leaderboards, and competititve play against friends.

VadimPR: https:&#x2F;&#x2F;telephone.health, which shows how well LLMs can take narrative medical text, convert it to a structured form (FHIR R4, for application consumption), and then convert it back to narrative text for human consumption.Interesting findings include Mistral doing better than Gemini 3 Pro in certain usescases, cross-LLM works better than one LLM to another, oh and - the cost all of of this. So, so expensive.

spaceman3: Been working on a solution to my meeting fatigue. I sit in way too many of them where I'm only there "just in case someone has a question" and realized I needed a way to safely not care about my meetings.The idea is: you join a meeting, hit start on the app, minimize, and go do actual work (or go make a coffee). When someone says your name or any keyword(s) you set, you get a native macOS notification with enough context to jump back in without looking lost. It uses whisper and is 100% local and doesnt leave traces, also very OE friendly.https:&#x2F;&#x2F;pingmebud.comWould love to hear what you think, especially if you're drowning in meetings too.

dvh: I'm trying CM108AH with external ADC (for lower mic noise). I'm at the stage that I opened datasheets for both and started kicad.

ryan14975: Eazip (https:&#x2F;&#x2F;eazip.io) — a REST API that bundles remote files into a downloadable ZIP.POST a list of URLs, get back a signed download link. Your server never touches the file data.Built it because I kept writing the same server-side ZIP streaming boilerplate on every project — memory spikes, connection timeouts, ZIP64 edge cases. Now it's one API call.Zero egress fees, ZIP64 support (4 GB+, up to 5,000 files&#x2F;job), signed expiring URLs. Free tier included, no credit card needed.

edf13: Building grith — OS-level syscall interception for AI coding agents.The problem: every agent (Cline, Aider, Codex, Claude Code) has unrestricted access to your filesystem, shell, and network. When they process untrusted content — a cloned repo, a dependency README — they’re prompt injection vectors with full machine access. No existing tool evaluates what the agent actually does at the syscall level.grith wraps any CLI agent without modification. OS-level interception captures every file open, network call, and process spawn, then runs it through 17 independent security filters in parallel across three phases (~15ms total). Composite score routes each call: auto-allow, auto-deny, or queue for async review. Most will auto approve - which eliminates approval fatigue.Also does per-session cost tracking and audit trails as a side effect of intercepting everything.https:&#x2F;&#x2F;grith.ai

xnacly: Each syscall taking 15ms on top of the normal considered costly time taken for context switching to the kernel seems excessivly slow, no?

edf13: It’s fast in terms of a response from a LLM model - but it is part of the system I am quite active on at the moment to ensure it’s performant as possible

kralos: A minimal build script of Hyprland from latest tag on Ubuntu 26.04https:&#x2F;&#x2F;gitlab.com&#x2F;kralos&#x2F;hyprbuntu

unlimit: Building a boring POS (1) using various AI tools just to check what can I do with these tools. I have used claude, gemini and now using antigravity. I have not done a single edit manually.I got it all done in probably an hour or two. But done in 10-15 min blocks over many days.(1) https:&#x2F;&#x2F;pos.unlimit.in

ehnto: An immobiliser for my car. Had trouble finding devices that would cover the specific attack vectors my car would be susceptible to. Checked my insurance, no specific clauses around immobilisers, check relevant road laws, no issues there.I have a fairly novel approach to operating it, and in the case of one time theft prevention security through obscurity is actually a great approach. The assailant only has a short time to pull the car apart and solve the puzzle, couple that with genuine security techniques, a physical aspect, and it should be pretty foolproof.It can still be towed away, etc, not much to be done there except brute force physical blocks. Most cars get stolen here to do crime in that night so it's not as common.

herol3oy: I working on a service[1] for myself to track visually the first page of some news websites hourly. Hosting the agent on my RP5.[1]https:&#x2F;&#x2F;kiosk24.site

John23832: How is this different than @‘ing someone in the chat apps we all already use, and that you’ll actually be responding to the ping in?

rishikeshs: I'm building a small tool called FormBeep[1] that sends a notification to your phone when someone submits a form on your website.It started as a client problem, then something which I also experienced so decided to built it. It's just one small script and work seamlessly across platforms.[1]https:&#x2F;&#x2F;formbeep.com

cure_42: Curious, were you already aware of ntfy.sh (which has webhooks) when you built it?

lastodyssey: https:&#x2F;&#x2F;playdropstack.comNot similar to linetris but its tetris meets a block puzzle

voodooEntity: Ishikawa : a framework&#x2F;architecture for automated Attack Surface Mapping & Vulnerability scanning- golang based architecture- information is dynamically mapped into one central directed knowledge graph- default multithreading- utilizes existing tools (such as nmap&#x2F;nuclei&#x2F;katana&#x2F;wfuzz&#x2F;....) instead of reinventing the wheel- architecture is (tldr) a self supervising logic in which every worker is also a scheduler that based on delta causality uses cartesian fanout and graph overlay mapping including local only witness nodes to dispatch new "jobs" without having a central scheduler or the necessity to scan a central total job queue to prevent duplicate executions.In this architecture every "action" that can be executed defines an input structure necessary. If the previously mentioned mechanic identifies a possible job execution it will create a job input payload which will automatically be picked up by a worker an executed. Therefor every action is a self containing logic. This results in a organically growing knowledge graph without defining a full execution flow. It is very easy to extend.I worked on this for the past ~10 years (private time). The sad truth tho is, while this project was initially planned to be open sourced - after i not to long ago for quite some bugs consulted a lawyer, i basically was presented with the fact that if i would publish it i could get sued due to germany's hacker and software reliability laws. So for now its only trapped on my disk and maybe will never see daylight.Im right now working on a blog article (thats why i even mention it) about the whole thing with quite more detailed description and will also contain some example visual data. Maybe will post it on hackernews will see.PS:The tool does not need llm&#x2F;nn.

chrillemn: https:&#x2F;&#x2F;github.com&#x2F;Chrilleweb&#x2F;dotenv-diffEnvironment variable checker - pretty niche.What would make you use this? does this miss anything useful?

jonaslanglotz: I'm working on site that let's you check when a manned space station was last directly over your house.It's a reference to https:&#x2F;&#x2F;xkcd.com&#x2F;2883&#x2F;, which I've always liked and was suprised there was no tool to check when you last had astronauts over for dinner.Looking up the location of the ISS at a specific time is easy. Looking up the closest passes of the ISS to a specific location for the last 30 years on-demand is more complicated.

mlrtime: For those wondering why there are downvotes, the site immediately asks to connect your crypto wallet and won't stop.Warning: Do not lick on the link.

akoskomuves: An opensource AI analytics tool with option for teams to track everything on a dashboard. Happy to get feedback or contributions: https:&#x2F;&#x2F;getpromptly.xyz

yoz-y: I realized that there is no journaling program I like, so I wrote my own. Authoring is done purely by iOS shortcuts and is writer (the only thing I want is to create a new entry, or create a new entry with a photo and metadata from said photo)Rendering is done by a go server. I wanted to learn go for quite a while and this is the perfect excuse.

hudecekdev: I was interested in the idea of generating vector graphics with simple scripting language. The "simple" did not happen, but... I launched https:&#x2F;&#x2F;scriptdraw.com and I have lots of fun with it. My goal is to make the language much simpler than it actually is and then create a lot of generators (for example, gears!).

pranshuchittora: Building Universal mobile devtool — control iOS Simulators, Android Emulators, and real devices from a single dashboard and CLIGitHub: https:&#x2F;&#x2F;github.com&#x2F;pranshuchittora&#x2F;simvynDo give it a try, Thanks!

nirvael: Using a Muse EEG headset to read brain activity and use that to drive the output of a GAN. Similar to other projects that try to visualise or decode thoughts, but at the moment it's an art project. Obviosuly quite limited by compute and hardware. I'm sort of looking for collaborators &#x2F; co-founders &#x2F; opportunities in the AI + neuroscience + creativity space.

kwakubiney: I’m working on a small deployment tool called push2start[1]. The goal is to make Docker Compose apps easier to deploy from a laptop to a remote server without a lot of custom scripts. Right now, I’m trying to keep Compose as the source of truth and avoid creating another mini orchestrator. You point it at a compose file, it transfers only the images that need to come from local, then deploys and gives status, logs, and restart controls from one CLI.[1]https:&#x2F;&#x2F;github.com&#x2F;kwakubiney&#x2F;push2start

sailorganymede: Value-study-practice-o-matic is the best name I've come up so far. It's just an automated way of practicing rendering when painting.

seriocomic: Working on an all in one "platform" that runs multiple different checks on a website&#x2F;domain. Got sick of having to run different checks in different places to ensure everything is at it should be - SSL, HTML, SEO, redirects etc.Extended the checking to monitoring and change detection&#x2F;alerting. You can try for free at https:&#x2F;&#x2F;www.augsentric.com - built for my own needs, but made it for others if there's interest... feedback welcome

GSSmarin: It would be cool if you could see the image&#x2F;video again after choosing. I always want to watch it again after a wrong guess.

ryan14975: Eazip (https:&#x2F;&#x2F;eazip.io) — ZIP remote files in one API call.I built a service that lets developers bundle remote files into a ZIP with a single POST request. You send a list of URLs, we fetch, package, and return a signed download link.The problem: creating ZIPs from remote files (S3, R2, CDN) usually means downloading to a server, zipping locally, managing temp storage, and cleaning up. It's surprisingly painful at scale — especially with large files or thousands of items.Eazip handles all of that. ZIP64 support for files over 4GB, up to 5,000 files per job, zero egress fees on downloads, and no infrastructure to manage.Use cases so far: e-commerce photo bundles, document delivery (invoices&#x2F;contracts), creative asset distribution, and backup&#x2F;export tooling.Free tier available, no credit card required. Would love feedback from the HN community.

domh: Oh actually, sorry I lied. I recently switched to Vanadium as my default browser which is the modified Chromium instance that ships with GrapheneOS. Apologies

mnky9800n: rainy-city.com! rainy-city.com is an ambient rain sound generator that is also a kind of city simulation. it is my recurse center project. it's suppose to be more of an ambient experience than a city simulator. it's a total work in progress, I've implemented buildings but haven't made a PR yet because they don't really work the way I want them to, and so I had to rebuild the tiling for them. So right now, there is no city. lol. just rain. but eventually it will have all this stuff you would expect. there are whales.https:&#x2F;&#x2F;rainy-city.com&#x2F;

jmstfv: I've finally finished the long-abandoned project that I've been meaning to build for a while.If you use Stripe Billing for subscriptions, your customers can specify reasons why they cancelled (e.g. too expensive, not using it, switched to competitor, etc.). However, to access those, you either have to use Stripe Sigma or pull them from the API. I wanted to build a more convenient way to access those (and also act upon them).I've submitted the app to Stripe's App Marketplace, but I have a limited number of test invites to send out if you're interested (I will happily waive your subscription for 3 months).https:&#x2F;&#x2F;dunningbear.com

softwarehippie: As a personal learning project on how to write efficient GPU code I'm trying to implement different shortest-path algorithms on the GPU. This is notoriously one of the cases where a simple algorithm like Dijkstra on the CPU will beat many implementations on the GPU.It has been a lot of fun to learn about Vulkan &#x2F; GLSL and the GPU execution model to figure out why the CPU is so much faster than the GPU. I'll be open sourcing the code soon but so far I'm documenting my journey in a series of blog posts. First one of the series is https:&#x2F;&#x2F;www.execfoo.de&#x2F;blog&#x2F;deltastep.html

pjc50: The aesthetic is so incredibly 1998. Reminds me not just of SimCity 2000 but the lesser played "A-Train", with its gentle day-night cycle.

stuartdev: Working on Book Reading Habit: https:&#x2F;&#x2F;bookreadinghabit.comBuilt it because I wanted to read more, but most reading apps either feel too passive or turn everything into social noise. What worked better for me was making reading easy to start: short 5–10 min sessions, pick up where you left off, minimal friction.So the app is basically centered around habit formation, with stuff like notes, progress tracking, session extension, shelves, and simple organization.I care a lot about keeping it quiet: no ads, no feed, no unnecessary clutter.Still early. Mostly trying to understand what actually helps people read more consistently.Currently only available for iOS, but might release an android version in the future.https:&#x2F;&#x2F;apps.apple.com&#x2F;us&#x2F;app&#x2F;book-reading-habit&#x2F;id674291326...

BrunoBernardino: My wife and I continue to work on Uruky, a EU-based Kagi alternative [1]. Since last month we got deals with a couple more search providers but we’re still waiting for EUSP&#x2F;STAAN to provide us with an API key (we have progressed through a few more forms and signatures and legal stuff, though).We’ve continued to get some paid customers and have exited beta last week, given everyone seemed to be quite satisfied and there hadn't been requests for changes, only some specific search providers.Because of bots there isn’t a free trial easily available, but if you’re a human and you’d like to try it for a couple of days for free, reach out with your account number and we’ll set that up!Thanks.P.S.: Because people have asked before, our tech stack is intentionally very "boring" (as in, it generates and serves the HTML + bits of JS to enhance settings and such — search can be done without JS), using Deno in the backend (for easier TypeScript), PostgreSQL for the DB, and Docker for easier deploying.[1] https:&#x2F;&#x2F;uruky.com

kleiba: Given the notorious European branding, consider renaming it eureuky ;-)

Hendrikto: I remember reading that Docker Compose is for development environments only, and should not be used in production. Did that change?

kwakubiney: Nope! This is for development purposes only. Say, for example, you have a frontend team that wants to connect to a service, and that service talks to other services to get a response, and you sort of want like a central point of connection for the frontend team just for development purposes only, not for production.

dondoron: I'm not an entrepreneur, just a developer with some side projects and zero marketing skill. So this would be ideal for me. However, given my non-entrepreneur mindset, I immediately think it's too expensive &#x2F; does not pay off for me when I don't see any pricing indicators. It would be great to see some success stories with numbers.

cahaya: Building Cursor IDE, but for knowledge workers. Domain will go live soon on https:&#x2F;&#x2F;document.bot

rcgeorge23: We're building Aucly: https:&#x2F;&#x2F;aucly.co.uk&#x2F;It's an auction website for schools, charities etc without the exploitative transaction fees.My wife and I are pretty heavily involved in our son's school PTA (parent teacher association) and have helped run school fundraising events for a few years, so we feel sort of like domain experts in this area :)

kleiba: Besides the technical challenges, how difficult is it to handle the legal aspects? I imagine taxes, liabilities, etc. must play a big role?

esperent: Very cool, wishing you the best of luck with this.One bit of feedback from me, take it or leave it, but the name doesn't feel appealing or memorable. What does it mean?

vintagedave: It makes me think of the Uruk-hai from Lord of the Rings. To me that is not a positive connotation. I feel bad writing anything even slightly negative about what is a really, really awesome project, though, and I hope that you meet with success :)

a_c: It's so simple that I didn't think much of it. Maybe I should

vintagedave: This sounds great, and I like it being EU-based (and, presumably, not reusing Yandex like Kagi famously does?)Could you share more info about how you're building it? Like Kagi it wraps &#x2F; reuses multiple other providers? How do you do that affordably, and how do you merge the results together into a good answer?

imetomi: I am building a voice interview&#x2F;survey webapp that helps product teams conduct product research faster. You can try it at https:&#x2F;&#x2F;intervio.appAny feedback is welcome :)

levleontiev: Working on Fairvisor — a tool for API governance and usage control.The problem: one buggy integration, scraper, or infinite retry loop can suddenly explode your API costs or overload infrastructure before anyone notices.Fairvisor acts as a guardrail in front of your API:per-tenant and per-route rate limitsrequest budgets and soft&#x2F;hard capsanomaly alerts for sudden spikesThe edge component is open source (OpenResty &#x2F; Nginx + Lua) and the SaaS part provides policy management and audit.Still early, validating whether teams would use something like this instead of building internal scripts.https:&#x2F;&#x2F;github.com&#x2F;fairvisor&#x2F;edge

tourist_petr98: I just became a father and feel like it could be helpful if I have an app tracking my son's status. He has premature birth and we're all very worried about him.So I vibe coded: https:&#x2F;&#x2F;apps.apple.com&#x2F;us&#x2F;app&#x2F;bebilog&#x2F;id6759827652

kilroy123: This week I'm on project #20 of my 25 projects in 25 weeks challenge! One was on the front page of Hacker News this weekend. It was humbling.https:&#x2F;&#x2F;pulsefeedback.io

looperhacks: How do you know that the videos are AI or not? For many of them it's pretty clear, but I imagine not every user is labelling their AI uploads properly

tomwojcik: I only add the ones where its proved its AI, fe. if it has SynthID or some users found obvious AI mistakes. I have adding proof on the roadmap, but it's a bit tidious and there's no point in making it without a traffic.

bambax: Congrats! But what is a spreadsheet "engine" as opposed to a spreadsheet program?

tomwojcik: Hmm, I will consider adding "close" button for the overlay popup. Thanks for the feedback

zimpenfish: * Reconstructing `$HOME&#x2F;git` after an unfortunate `rclone sync` wiped it. It was not fun discovering that my backup was on the wrong `git` directory and also that I'd not committed some stuff for ... years. Lesson learned, etc. * Implementing three new bot ideas. * Trying desperately to stay out of the "we must vibecode!" juggernaut's path at work. * Wasting hours having to manually download Every. Single. Model. from my MyMiniFactory library because they don't provide an API, a bulk download, or a sync to something like Dropbox. (1500 down, about 4000 to go!)

pain_perdu: This looks really useful! FYI my day job is at a frontier voice ai lab focused on hyper-realistic low latency TTS (we're a commercial spinoff of Kyutai called Gradium). Happy to hook you up with a bunch of free credits if it's at all useful. Contact me anytime via colin at gradium dot ai.

samcolson42: https:&#x2F;&#x2F;GigClub.liveLetterboxd for live events. Currently a waitlist system in place, and we're very UK-focussed.The long-term plan is to build a really enthusiastic community and then become a primary ticket seller.

vintagedave: > automatically yields after each logical line of codeI've become more and more interested in code that yields (coroutines etc, read this fascinating article on HN just a couple of days ago: https:&#x2F;&#x2F;willhbr.net&#x2F;2026&#x2F;03&#x2F;02&#x2F;async-inject-and-effects&#x2F; )Can you share more about this? How the async model works? Why it does -- is it a performance guarantee given the RTOS comment? Or is it more about the state machine idea, and how or why does yielding every line (not, say, every state transition, though I have no idea if or why that would be more useful) relate to that?I mostly just have lots of questions because it sounds fascinating, so if you're looking for an excuse to talk about it, please count this as that excuse!

davehcker: Building wireless (LTE-based) sensors for most major horticultural sensing needs. Measurements include:- CO2. Side note: I was surprised to find that most (all?) CO2 sensors used in closed plant production setups are not meant to operate below 400 ppm.- Air temperature, pressure, relative humidity- Photosynthetically Active Radiation (PAR)- Addons like: wind speed, wind direction, soil moisture and Electrical Conductivity (EC)- The coolest and most challenging: pH, EC, and flow rateThe hardest part has been running everything on battery while maintaining accuracy and using LTE (2–4G) and not common LPWAN options like LoRa. I'm primarily a software guy, so the learning curve has been huge.

tr3ntg: Logged in to agree with all the other comments: this is so, so pretty. Will try the demo soon.

fasterik: I wanted to learn more about computer graphics, so I'm writing a 3D software renderer in C. So far I have a solid implementation of triangle rasterization, perspective projection, depth buffer, clipping, texture mapping, diffuse lighting, and gamma correction. Currently struggling with shadow mapping, which is the last feature I'll add to the renderer before moving on to procedural generation of meshes and textures.Once I'm done with this project I'm planning on making a series of YouTube videos going into the code and the algorithms.

hsdev: I'm currently working on https:&#x2F;&#x2F;FaunaMap.app (web&#x2F;Android&#x2F;iOS) which lets nature enthusiasts see which birds, mammals, reptiles, etc. can be expected at any location worldwide using the past 20 years of GBIF observation data. It features an interactive global sightings map, color-coded to quickly spot recent rarities nearby. Public birding hides from OSM and a hotspots heatmap are included for trip planning. Users can quickly log large numbers of observations in the field. Observations with images appear in an Instagram-like feed for interaction with other users. Personal species life lists (global, per country, and custom locations) are also included. Feedback is very welcome :)

sersi: I've been using a VM for claude code (probably would keep doing that as I do like how much control I have over it by doing that) but this is definitely a useful tool, I'll happily use that in the future.

dzjkb: +1

m00dy: https:&#x2F;&#x2F;deepwalker.xyz - Mobile Agent.

tkocmathla: I got this itch too when I came across tinyrenderer [1] and worked through the early lessons through shading, but didn't quite finish the texture mapping yet [2]. It was fun to work in pure C from first principles, even side-questing to write a simple TGA file reader and writer.I'd be very interested to see your tutorial when it's done![1] https:&#x2F;&#x2F;haqr.eu&#x2F;tinyrenderer[2] https:&#x2F;&#x2F;github.com&#x2F;tkocmathla&#x2F;tinyrenderer

jundressed: Built GhostDance — overlay any TikTok dance as a ghost on your camera to practice in real time.Been learning dance moves from TikTok but hated the pause&#x2F;rewind loop on my phone. So I built a web app that overlays the original dancer as a translucent ghost directly on your camera feed.Upload any video → ghost appears → you follow → record yourself → export. No install, works on mobile browser.https:&#x2F;&#x2F;ghostdance.app&#x2F;Feedback will be much appreciated!

p2hari: Super cool. We are also doing something similar but not open sourced (still thinking about it). We are doing e-commerce, pos, kitchen-screen etc. Both for product and services so from Yoga Studio&#x2F;Salons to Take-away Restaurants or ecommerce shops. However focussed only in Europe. Since we are working with a Europe payment processor and early users are getting 0% in transaction fees. The live demo is still not working and we are onboarding on a case by case basis. https:&#x2F;&#x2F;storenu.com

anotheryou: Delving on to personalized software again now that AI agents code it for me with little hand holding.Instead of building scrips here and there I'm attempting my own everything app. Lets see if that's a good idea :).Starting with android home screen and widget sync to server&#x2F;desktop. So e.g. calendar notifications happen desktop first, then escalate to mobile etc. Also phone as mousepad (for using my projector from bed). Just feature creeping it all in without regrets so far.In general I feel like feature creep needs to be reevaluated. UX must not be destroyed, but features cost less now.

Havoc: Doing similar except decided against a single app. Lots of small apps behind a reverse proxy with mTLS auth instead.

Asmod4n: I’ve written a CBOR implementation as a mruby c extension in an afternoon and am about to officially release it soon.It’s my first project where I’ve worked with claude: https:&#x2F;&#x2F;github.com&#x2F;Asmod4n&#x2F;mruby-cbor

jtbetz22: Agentic code construction has broken traditional models for code review - the volume is just too high for humans to keep up with.There are some good tools out there for automating pr review; IMO, they don't catch enough, and they catch it too late.I've been experimenting with some ideas about a very opinionated AI code reviewer, one that makes an ideal tradeoff between cost and immediacy (eg, how soon after composition does the code get feedback).Currently in an invite-only alpha, but check out the landing page and lmk if you'd like to be a trial user!https:&#x2F;&#x2F;getcaliper.dev&#x2F;

thomasmg: Since about two years I'm working on a new systems programming language [1] that is supposed to be nearly as fast as C, memory safe, and as concise and easy to learn as Python. Right now I'm trying to integrate Perceus, the ref-count optimization of Keka.[1] https:&#x2F;&#x2F;github.com&#x2F;thomasmueller&#x2F;bau-lang

rixed: Went straight to what matters to me: data structures, or how they are defined ("Show me your tables"). And couldn't find any mention of anything beyond arrays and enums. Should one conclude that there are no typed unions, no structs, no objects?

mikenikles: I build Seaquel, the database client I've always wished I had. It's open source, works offline and doesn't track what you do.It has a visual query builder and separate SQL tutorial.https:&#x2F;&#x2F;seaquel.app

fasterik: tinyrenderer looks impressive! The tutorials look good too. I might have to borrow some ideas from them.No idea when I'll get around to making the videos, but if you want to follow my channel it's at https:&#x2F;&#x2F;www.youtube.com&#x2F;@fast_erik

BrunoBernardino: Thanks! We'll happily take suggestions, but I read it like "Euro-key". My wife also doesn't love the name, but we couldn't come up with (or find) anything with 5 letters or less that sounded decent so far.There's no specific meaning, though I can't say I dislike the close name matches with Uruk-hai [1] and Uruk [2]! :)[1]: https:&#x2F;&#x2F;lotr.fandom.com&#x2F;wiki&#x2F;Uruk-hai[2]: https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Uruk

alabhyajindal: Hi Bruno - this looks great! I remember collaborating with you a couple times on Kagi's browser extensions. Was there a specific moment that made you want to work on Uruky, or was it because of the overall direction Kagi is heading in?

Havoc: I’ve seen implementations which need a magnet pressed to the door plastic in a specific place. Security through obscurity as you say but clever anyway - you basically need both a magnet on hand and know where to hold it.Or time to pull the car apart

miguelmichelson: I'm working on Rauversion https:&#x2F;&#x2F;github.com&#x2F;rauversion&#x2F;rauversion, an open platform for independent music communities that combines music publishing, events, and marketplace tools in a single place. Artists can upload tracks, albums, and playlists with metadata, audio processing (waveforms, analysis), and embeddable players with chunk-range loading to save bandwidth. It also includes ticketing for events (QR validation, Stripe payouts), streaming integrations (Twitch, Zoom, etc.), a magazine system for publishing articles, and a marketplace to sell music (digital or physical), gear, merch, and services. The goal is to give underground scenes a self-hosted infrastructure for releasing music, organizing events, and sustaining their communities.

theturtletalks: Looks really interesting, would you say it’s an opensource Bandcamp alternative?

miguelmichelson: Yes, it drew a lot of inspiration from Bandcamp and SoundCloud, but nowadays we are focusing on developing our own features.

BrunoBernardino: Yes! I definitely read it like that, but we wanted few letters! :D

BrunoBernardino: Thanks! Sure. We are 100% transparent on all the search providers we're using, you can see them in the FAQ, and Yandex isn't used.Initially we called all search providers and merged the results in a round robin fashion (so first of the first provider, first of the second provider, first of the third provider, then second of the first provider, second of the second provider, and so on), deduplicating them, but this was becoming very costly and inefficient once we had 3 and more search providers (most providers will return results within 500ms, but not infrequently one would take up to 2s or more — we timeout there, so I don't know if it'd take much more —, slowing everything down), so now we give everyone the choice of which providers to use first, and we pick results from the first two (we're actually considering switching to just the first, as costs are still a bit high and we don't want to increase pricing).I hope that provides some more clarity! Happy to answer any more questions.

popupeyecare: Nope. Just iterated slowly. Started by looking templates I liked on dribbble.

thomasmg: Objects and structs are described in "Types" [1]. There are no typed unions currently (maybe I'll add them, not sure yet), but there are "Traits" [2].[1] https:&#x2F;&#x2F;github.com&#x2F;thomasmueller&#x2F;bau-lang#types [2] https:&#x2F;&#x2F;github.com&#x2F;thomasmueller&#x2F;bau-lang#traits

rukshn: Happy March everyone,I am working on Entangle, https:&#x2F;&#x2F;entangle.cloud something for me to learn and play with LLMs and AI.It is not ground breaking but let your website to have an AI chat bot &#x2F; agent with minimal integration effort. Also was a good way for me to learn how to keep things safe, prevent prompt injection etc.Looking for feedback and feel free to give it a try, happy to try it with your project documentation or developer docs.

deepvibrations: Nice, what front end charting library are you using? Looks very slick!

ciju: d3

mosselman: Very fun. You have hidden the controls on the video, is it because you want it to be more of a game and prevent people, normies at least, from seeking through the video or is it for some other reason?

BrunoBernardino: <3

BrunoBernardino: Thanks for the kind words! They might not be "standard pretty" but I'd say they're arguably resilient and disciplined, so it's not all bad! :D

secretdark: I've been working on an MQTT Broker&#x2F;Topic tree explorer. It's intended to help someone understand what kinds of data are moving through their broker, what the busiest data is, and just generally be pretty. https:&#x2F;&#x2F;ryanbateman.github.io&#x2F;mqtt_vis&#x2F;OSS, MIT licensed. Feedback welcomed!

swah: Is the frontend component from scratch? Must be quite hard to get that right. I wish Dyanlist (from the same talented people who are doing super well with Obsidian...) was open-sourced so we had a good model for outliners.

anotheryou: cool! what features?I have or am planning:- escalating reminders- always on display- upcoming meetings &#x2F; calendar- have "website + prompt = widget" app that needs integration- want 2 tier prio email filter (important, personal, ignore rest)- android launcher with decent ergonomics (match "ff" to firefox, most used prioritized, launch with enter etc.)- maybe some agent integration

ElFitz: Oh, so many things. I guess that’s both the blessing and the curse of agentic ai today.The most fun is a simple Claude Code in a loop, Boucle, which builds and iterates on its own framework[0][1].The first thing it built was a persistent memory. Now it has finally built itself a "self-observation engine" after countless nudging attempts. Exploring, probing, and trying to push back the limits of these models is pure chaos, immensely frustrating, but also fun.Aside from that, some sort of agent harness I guess we call them? Putting together a "system" &#x2F; "process" with automated reviews to both steer agents, ground them (drift is a huge pain), and somehow ensure consistency while giving them enough leeway to exploit their full capabilities. Nothing ready to share yet, but I feel that without it I’ll just keep teetering on the edge of burnout.[0]: https:&#x2F;&#x2F;github.com&#x2F;bande-a-bonnot&#x2F;boucle-framework[1]: https:&#x2F;&#x2F;blog.boucle.sh

yreg: We really do need more new isometric grid based games. They are less realistic but it is _so_ satisfying to build in them.I've commented on it before: https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=39810716

BrunoBernardino: Hey Alabhya! Nice meeting you here! :)I don't think Kagi is heading in a bad direction, but I also think there's value in a product that's solely focused on private and personal search, that doesn't have to be as expensive or big (team and resources-wise) as they are.I hope that makes sense!

dash2: Here is my fun mini-project:https:&#x2F;&#x2F;apps.apple.com&#x2F;us&#x2F;app&#x2F;kaien&#x2F;id6759458971I wanted a way for my kid to learn the alphabet, but without a UI that looks & behaves like a slot machine. It's all maximally slow, relaxed and designed to be easy to put down.

mparas: Working on Sensonym (https:&#x2F;&#x2F;sensonym.com), a language learning app that teaches vocabulary through physical phone interactions. Shake your phone to learn "earthquake," blow on it for "wind," smile for "happiness." Nearly 40 different interaction types using accelerometer, gyroscope, camera face detection, microphone, etc.Built with React Native&#x2F;Expo. The hardest part hasn't been the sensor code, but rather designing interactions that feel natural rather than gimmicky. Each word needs to map to a physical action that actually reinforces the meaning. Solo dev, live in German app stores now. Previously co-founded another language learning startup (Sylby, partnered with Goethe Institute), so this is take two with a very different approach.

hmokiguess: Love these, really cool!

codazoda: Balance Buckets helps you set aside money for the things you care about.It’s two-minute envelope accounting for your bank balance.https:&#x2F;&#x2F;buckets.joelryan.com

kvgr: Very small app for framing photos on Mac&#x2F;ipad&#x2F;iphone. I know some web alternatives. But when i wanted to add borders to photos I took to upload to IG i used imagemagick. I want to make something stylish(no tacky borderds), also usable for batch processing. I have prorotype and need to fix some issues.

nullandvoid: https:&#x2F;&#x2F;mealplannr.io The end game is no&#x2F;low touch weekly meal plans send directly to your inbox, with meals you love to cook but with none of the hassle around planning the meals, shopping list etc (which I spend hours doing every week).An important feature for me was improving the recipe discovery experience, you can build a cookbook from chefs you follow on socials (youtube for now), or import from any source (Web, or take pic of cookbook etc) - it then has tight &#x2F; easy integration into recipe lists.Utilising GenAI to auto extract recipes, manage conversions, merge&#x2F;categorise shopping lists etc - as-well as the actual recommendations engine.If anyone is interested in beta testing &#x2F; wants to have a chat I'll look out for replies, or message mealplannr@tomyeoman.dev

robin_reala: I finally, after a couple of years off, picked up work on a Standard Ebooks[1] edition of The Book of the Thousand Nights and a Night. I made a new years’ promise to myself to get it as done as possible by the end of the year. If it doesn’t happen I’m not going to be too hard on myself though, given the 5K endnotes and 1.5M overall word count. But we’ll see![1] https:&#x2F;&#x2F;standardebooks.org&#x2F;

jkubicek: I’m learning Godot and writing a basic game for my kids.Coding agents are amazing and make me (feel) productive, but they really suck the fun out of programming.I’m sure it’s possible to create a Godot-based game with an LLM, but I’m not sure how, so I’m forced to do everything the old-fashioned way – reading the docs.

lancekey: For over a year now, I’ve been working on Compute Prices (https:&#x2F;&#x2F;computeprices.com).It’s been a great way for me to better understand the cloud GPU industry, learn about data collection, normalization and use agentic coding to build a side project.One thing I’m working on is distinguishing spot vs on demand prices and listing those separately. Also, including inference pricing for non-text AI models.What features or data would you like to see me add next?

alessioalex: I know Kagi is using Yandex (Russian search engine), that's why I am no longer using it.Is Uruky using Yandex?

whatl3y: I'm most excited about reducing friction for digital payments of APIs and resources in the agentic commerce world.I think the first step is standardizing HTTP 402 using traditional, familiar payment rails like Stripe, then we can move to things like on-chain or other rails later.I am building https:&#x2F;&#x2F;stripe402.com to try to make it dead simple for those building APIs&#x2F;resources to get paid per request through stripe without user's needing to sign up for accounts, get API keys, any of that normal painful workflow required today.Check it out and feedback welcome!

michaelanckaert: Working on improving AI Nexus - my custom LLM frontend that exposes all AI Models in a single interface: https:&#x2F;&#x2F;getainexus.com&#x2F;

alessioalex: A macOS screen recording CLI application that can record: screen, mic(s), camera(s), system audio, iPhone&#x2F;iPad screen. You can select different tracks with their own options (video encoding, audio encoding, filename, combine camera with mic for example or even screen + system audio + mic). It also tracks clicks, scroll, keyboard and generates closed captions automatically at the end. Now I'm working on adding 1-2 more features and an MVP is done.

codazoda: Me too. Maybe we could mastermind? Reach out, my email is in my profile.

vintagedave: That's a really cool idea. When I was a kid my data added in immobiliser to our car (flashing LED etc) with a hidden switch. It would have potentially taken quite some time to find if you didn't know where it was.Adding a puzzle is brilliant and I would love to read a blog about this. Post it here on HN ;)

Decabytes: I’m working on an R7R7-small scheme called Sable. The focus is on having good Windows support, vscode support, Lsp and Debug adapter protocol support. It is closer to SBCL and is image based, and builds with just the platforms native c compiler

BrunoBernardino: Hello! We are 100% transparent on all the search providers we're using, you can see them in the FAQ, and Yandex isn't used.

badpun: I get a lot of "UFO: Enemy Unknown" vibe from the art.

jacquesm: Still on time. It is almost two months now and this is such a deep subject and there are so many little tricky bits that I wonder if I will be able to complete the thing but there is still (slow) progress. I never suspected the amount of hard work that goes into building something that is stable at the nano second scale. But I'm becoming more appreciative every day ;)

btylke: I'm developing a system that uses graph differentials to understand what has changed between library versions and upgrades the target system without breaking things. [0]Because source isn’t always available, it scans the bytecode of an application and the new library, building a full graph of each component in Neo4j to determine what breaking changes impact the target application. This is then translated into tickets and prompts to drive an LLM to make the appropriate changes.Handling library upgrades is rarely interesting and just adds to our overall technical debt, so it has been nice to automate it away so that we can focus on features and functionality. It supports Java and .Net currently and we’re actively adding support for other languages.[0] https:&#x2F;&#x2F;codelogic.com&#x2F;

rhoopr: Can you clarify how Statphone deals with the problem of random spam calls hitting the number by chance and ringing everyone? I assume that’s how most spam operates these days, just brute force on number permutations. I love the idea!

robinweller: I’ve been building Adversa [1], a tool that monitors competitor websites and explains what actually changed.Most monitoring tools alert every time anything changes. That usually ends up being navigation tweaks or small copy edits. After a while the alerts just get ignored.Adversa focuses on meaningful updates instead. It detects changes across competitor pages and uses AI to summarise what changed and why it might matter.I originally built it because I was manually checking competitor pricing pages and changelogs. I also wanted something practical for smaller SaaS teams. A lot of existing tools are either enterprise-priced or the free tiers are too limited to be useful.Still early and trying to learn what people actually want from this kind of tool.[1] https:&#x2F;&#x2F;adversa.io

PetriCasserole: I would have loved this when I worked in commercial real estate. Monitoring competition may have hooked me but I think there's another layer to monitoring clients.

cryptoz: AST-based code modifications from LLMs: https:&#x2F;&#x2F;codeplusequalsai.com&#x2F;I'm interested in the idea that LLMs writing raw code and doing line-or-diff replacements will not be the future, but that having the LLMs modify the structure of the code may end up being the best.Also, I think that building LLM-powered webapps should earn the dev per token call; so I've built a margin into token costs where the end user is charged 2x the provider's token costs, and then I get 20% of the remaining and the dev gets 80%.

zimpenfish: I'll throw a third (fourth, fifth because I know a couple of people who'd play this on Mac but who have no access to Linux or Windows) request for a Mac version on the pile.

mbreese: I could see this being a very eye opening game if you added "Fan" and "Parent" modes. In "fan" mode nothing you said would affect the game, although maybe a player would laugh once in a while. In "parent" mode, you'd have a youth soccer game where whatever you said would confuse the player and they'd perform worse.Sounds like a fun project -- like a more interactive version of Football Manager.

pipnonsense: Neat ideas.One thing I am exploring is that, with LLM (and enough $ to pay the tokens) you can filter out offenses and hate speech in player communications.All typed message is effectively translated by the LLM as “coach speech” and what is put in the UI is the LLM output. Sure, it is not exactly the player words and can get expensive, but I think it can be a good solution

hoerzu: Open Source screener of polymarket for insider tracking https:&#x2F;&#x2F;poly gains.com

Brajeshwar: I like finalfinalreallyfinaluntitleddocumentv3.com Now you don't have to worry about getting domain names, you can version them all the way with the vX. The final boss can be finalfinalreallyfinaluntitleddocumentv3_final.com

michaelbuckbee: It was genuinely quite frustrating that all of the "normal" domain names were taken for this, but not actually used (basically everything "moniker.TLD").What was surprising was that all the prefix+suffix variants of app&#x2F;now, etc. were also taken so this was really just me trying to push it hard the other way.

robinweller: I have been suggested speaking to real estate businesses to see how useful it would be.A friend of mine used to work for a real estate company and said his company and their competitors were always at loggerheads and complaining about each other breaking rules etc. this would have stoked the fire a little!

AutoAPI: PostalAgent - https:&#x2F;&#x2F;PostalAgent.com – direct mail automation for people who've given up on email open rates.Email averages ~20% open rates on a good day. A postcard sitting on someone's kitchen counter for two weeks is hard to compete with. I've been building out the programmatic side. API, Zapier, and native integrations with Jobber and Zoho so you can trigger physical mail from the same workflows you already use for email.Shopify integration is almost out the door too, which opens up a lot of interesting abandoned cart and win-back use cases for stores whose customers have opted out of email.No bulk minimums, no design software needed. If anyone here wants to give it a try, reply or email me and I'll set you up with some free credits to get started.

SeanAnderson: Just a small project to assist with some stuff at work, but trying my hand at vibe-coding a "data science playground" to try and level-up a couple of people into feeling comfortable using Claude to write data analysis tools. I generated a bunch of synthetic data, that looks like stuff we might encounter on the job, and embedded trends into the data that can be revealed through statistical analysis. I encrypted the answers and put a lil LLM in front of the answer file. You submit answers to the LLM and it tells you warm&#x2F;cold by looking at the answer file. Hoping to basically gamify the learning process to make it easier&#x2F;faster to get data-driven results.

jackdev: My friends and I would often sit in pubs trying to guess the top 10 most streamed songs for a musician so I had a go at turning it into a browser game.https:&#x2F;&#x2F;topsongs.io&#x2F;Had a lot of fun doing it and it's more user friendly than trying to read off lists from stream aggregators online that have a lot of ads etc.First ever go at something like this so any feedback is appreciated!

gbro3n: VS Code Agent Kanban (just made it to the front page)https:&#x2F;&#x2F;www.appsoftware.com&#x2F;products&#x2F;developer-tools&#x2F;agent-k...It's a VS Code extension that implements a Kanban board backed by markdown files. It's set up to allow you to communicate with GitHub Copilot chat via markdown files, so you have a clear permanent record of your considerations, decisions and actions. I'd been getting great results with a similar but more manual workflow, so I built this to make managing the markdown files easier and to give me the ability to visually organise with some shortcut commands.

slig: I liked your onboarding on &#x2F;welcome, but the plan feels weird for me:- 1 Month instead of "Monthly" as it's a subscription and you're not really purchasing a "one month pass", correct?- the same for the other plans

chantepierre: Converting an app that started per-client deploy, single-tenant, cloud-ignorant and mono-node to multi-tenant, multi-node, cloud storage and a cluster of a few nodes.On one hand, I regret not having thought it could find a market and I now have to do this and plan a migration.On the other, I saved a lot of time going to customers instead of building the boring side first... So I don't know what to think of it.I find that most of the development work is now "ops" instead of user-facing features (either addition, removal, or polish) and am a bit perplex at this.

nhatcher: The "engine" is the computational part of it. And it is completely separted from the UI. You can use it from Rust, Python, nodejs or from the browser and eventually from a destop app.The important thing is that is all those cases the engine is the same. I

skypanther: This looks great and I'll probably order a report. A couple of small suggestions. First, the price is very reasonable, but I think you should be more open about what it costs -- maybe on the home page or at least the Order Report page. Second, I think you should tell what areas of the country (world?) that you can provide reports for, again on the main page would be great.

spaceman3: pingmebud is the equivalent to having @-mentions but in voice calls. Imagine a standup meeting at work where someone says "what do you think about this, John?" and you were not paying attention and have no idea about what the context of the conversation is. My app solves that.

bengale: That's a lot of fun, good work.

meandave: Crew Chief (https:&#x2F;&#x2F;crewchief.cc) — a Vehicle diagnostic and management tool. Plug in your OBD2 codes (or just describe symptoms) and get a structured diagnosis in under 30 seconds: ranked probable causes, DIY vs. shop cost estimates, severity rating, and matched parts&#x2F;repair videos.I have too many project cars and bikes, I wanted one place to store vin numbers for searching parts, and then just kept adding useful features.Supports 16 vehicle types (cars, trucks, motorcycles, boats, tractors, ATVs, RVs, etc.), not just cars. Also includes maintenance tracking, a browser extension that auto-fills your vehicle info on parts sites like RockAuto and AutoZone, a community-vouched trusted shops map, and a vehicle selling wizard with state-specific bill of sale generation.Free tier gives you 1 vehicle with a full diagnostic.

asciimoo: I'm working on a self-hosted search service called Hister with the goal to reduce my dependence on online search engines.Hister is basically a full text indexer which saves all the visited pages rendered by your browser. It provides a flexible web (and terminal) search interface & query language to explore previously visited content with ease or quickly fall back to traditional search engines.Here's a little summary of the background&#x2F;motivation&#x2F;beginnings: https:&#x2F;&#x2F;hister.org&#x2F;posts&#x2F;how-i-cut-my-google-search-dependen...Project site: https:&#x2F;&#x2F;github.com&#x2F;asciimoo&#x2F;histerWebsite: https:&#x2F;&#x2F;hister.org&#x2F; Read-only demo: https:&#x2F;&#x2F;demo.hister.org&#x2F;

englishspot: I didn't like any of the car maintenance apps I've tried, so I'm building my own. simpler, can be run locally (I run it in a k3s cluster). I don't think I have any stand-out features for it right now, or planned for the near future, but it works well for my purposes.

motoboi: Working on TRIPA, a internal pack format to save huge amount of small images to cloud storage without dying from the write costs.

loumaciel: I’m building Sift, a drop-in gateway that makes LLM tool use far more reliable when tools return large JSON payloads. The usual pattern is that agents paste raw tool outputs directly into the prompt, which quickly blows up context, causes truncation&#x2F;compaction, and leads to incorrect answers once earlier results disappear. Sift sits between the model and its tools (MCP, APIs, CLIs), stores the full payload locally as an artifact (indexed in SQLite), and returns only a compact schema plus an artifact_id. When the model needs something from the data, it runs a tiny Python query against the stored artifact instead of reasoning over thousands of tokens of JSON. In benchmarks across 103 questions on real datasets, this approach cut input tokens by ~95% and improved answer accuracy from ~33% to ~99%.

peter_retief: https:&#x2F;&#x2F;i.imgur.com&#x2F;mTyjQXs.png I am still building the "make money app" for some difficult users. :) Last update was calendar integration, everything besides the invoice is a sandbox, kind of like the Unix philosophy of pipes, lots of standalone apps.

glad_you_asked: Not a developer but have few ideas that I didn't pursue due to professional and personal responsibilities. One of them was a simple protein price comparison tool that allows me to find the value for money protein powder which is tested for label accuracy, heavy metals, amino spiking etc. I used to maintain an excel of my known brands and track which ones offered the best value without breaking my bank. I thought if I am looking for such data then there might be others like me. So I recently subscribed to Claude and was able to create a simple website from scratch. It's great that people can create their hobby projects so easily now.Link to website:https:&#x2F;&#x2F;compareproteinprices.com&#x2F;index.html

vinhnx: This month, I'm working on VT Code, a terminal-native coding agent I've been building in Rust (https:&#x2F;&#x2F;github.com&#x2F;vinhnx&#x2F;vtcode).This month I'm focusing on long-pending TODO items: self-benchmarking with Terminal bench (https:&#x2F;&#x2F;www.tbench.ai&#x2F;), fuzzing the security parsers (it executes shell commands, so the threat model is real), normalizing extended thinking traces across providers, and improving the agent UI&#x2F;UX and TUI components and harness.

edarchis: I think that it's a great opportunity to play with relatives. Each person can explain why&#x2F;why not and that's probably the main point.It'll also probably shut the mouth of those who think that they know better. This works with the driving license. Start a test with the whole family and watch the older men get a reality check.

We needed a real product as a sandbox to learn, so we built a tool that we'd use ourselves.There's a free tier. I'd love to hear any feedback on the product (or our marketing efforts!). Thank you!

marginalia_nu: Cooking up a NSFW filter for marginalia search.Pipeline so far has gone like this:* Use the search engine's API to query a bunch of depravity* Use qwen3.5 to label the search results and generate training data* Try to use fasttext to create a fast model* Get good results in theory but awful results in practice because it picks up weird features* Yolo implement a small neural net using hand selected input features instead* Train using fasttext training data* Do a pretty good job* for (;;) Apply the model to real a world link database and relabel positive findings with qwen to provide more training dataCurrently this is where I'm at Accuracy: 90.90% True Positive: 1021 False Positive: 154 True Negative: 2816 False Negative: 230 Precision: 0.8689 Recall: 0.8161 F1: 0.8417 There's a lot of vague middle ground and many of the false positives are arguably just mislabeled.

peter_retief: Reminds me of the chicken feed app I saw about 40 years ago, before the internet It would find the best price for protein, carbohydrates etc in chicken feed looking at raw products like bone meal and maize with current prices. Remarkable actually, I wonder what happened to it? Anyone else remember any apps before the internet?

abound: I'm working on a simple, single person, self-hostable scheduling app [1] (think Calendly or Cal.com) to replace my self-hosted Cal.com instance, as it's way overkill for my needs and annoying to maintain.I'm also using this as an experiment to see how to use AI tools to build a maintainable project of medium complexity. Too big to do in "one shot", but doable if decomposed into a few dozen tasks.It's going well! I think I only started Saturday morning and put in maybe 4-5 hours on it, and it's in pretty decent shape. Not ready for prime time yet, but only a few hours away from replacing Cal.com for my own use. The slowest part is that I'm manually reviewing the code, but that's part of the deal for this experiment.[1] https:&#x2F;&#x2F;git.sr.ht&#x2F;~bsprague&#x2F;schedyou

abound: I already posted in this thread, but then I remembered a few months ago I had posted about my ISP + web host project. [1]Since then, I configured all the hardware (switches, router, server, bastion host, etc), put it in a real colo, and am doing BGP with one upstream (with a second upstream and some peers on the way). This means I'm officially part of the internet! E.g. https:&#x2F;&#x2F;bgp.tools&#x2F;as&#x2F;55078I'm just working on some BGP and network hardening stuff, then I'll start putting real live services on the server. And in parallel, I'm working on getting the link from my home to the colo active, so I can be my own home internet provider.[1] https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=45870010

juanpabloaj: Thanks for the quote. Reading it, I can feel how a Tsutomu Nihei or Giger atmosphere envelops me.

PetriCasserole: Just commenting to let you know I enjoyed exploring your site and reading your posts.

kindkang2024: Fair point — really valuable feedback, thank you. Currently I took the easy dev path: connect a wallet, and your data gets associated with that address. Simple, but clearly a bad decision and caused a bad first impression.You're right, nobody should be forced to connect a wallet just to try the app. I'll work on changing this — the plan is to let users explore and watch freely, and only prompt for a wallet when they want to save words.For now and for better security, anyone interested can create a throwaway MetaMask wallet to try it — no gas needed, it's just wallet connect + SIWE sign-in for identity. (No other transactions will ever be issued.)

siverson914: I've written my own version of OpenClaw, but it's cloud-first so no setup or install. An early release, but I think its pretty neat and I'd appreciate any feedback: https:&#x2F;&#x2F;gipity.ai

psubocz: I'm building a small CAD tool for makers called dēlo.I started it because I wanted a CAD I would actually enjoy using myself. The idea is a simpler, assembly-first workflow instead of a full engineering CAD.It’s still very early and rough, but I recently got the first real loop working: model → export STL&#x2F;STEP → slicer → 3D print.The goal is something between Tinkercad and the big CAD tools - simple, local-first, and not locked behind subscriptions or cloud accounts.

spaceships: I'm working on a Chess improvement app https:&#x2F;&#x2F;blunders.ai.The main goal is letting people analyze their games and improve by studying their blunders. It uses stockfish and AI for analysis. You can chat with your games like "Why would I do ___ instead of this?"Also, there are the standard puzzles and openings type learning with improvement plans.

kushalpandya: Been working on Petrichor - native macOS music player [1]This has been my side project for nearly a year, and I also shared it here in HN when it was in alpha [2] and received a ton of feedback (and stars on GitHub).The project has evolved quite a bit since then, like having additional file format support, lyrics, Last.fm scrobbling, and more![1] https:&#x2F;&#x2F;github.com&#x2F;kushalpandya&#x2F;Petrichor[2] https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=44515266

order-matters: i love this and have been a long time complainer that browsers dont automatically operate this way.how does it handle forms or homepages with refreshed content? for example, the home page of hackernews - will it always show the latest feed from the last time i had a connection or will it store each time ive visited it ?

princeholdings: Two things I've been building this year, both trying to solve real problems I care about:https:&#x2F;&#x2F;talonwatch.com : I kept seeing founders discover their Stripe keys were public or their database was wide open, usually after the damage was done. Built a passive security scanner for vibe-coded apps so that's easier to catch early. Free surface scan, no account needed.https:&#x2F;&#x2F;thetracejournal.com : A small iOS journal that pairs a song with each entry. Music is tied to memory in a way nothing else is, and I wanted a place to capture that.

jaltekruse: Adding new openly licensed learning resources to the Kolibri offline learning platform. It is designed to be deployed in communities that lack consistent access to the public internet. They currently have a significant amount of English language content, but are limited in what they have available in the dozens of other languages they have translated the core software into. I'm trying to bring in new resources and then try to lead an effort to do translations of the best materials I can find to make the platform more useful to more people.https:&#x2F;&#x2F;community.learningequality.org&#x2F;t&#x2F;bringing-new-comput...Also trying to recruit people to teach tech newbies how to build their own handheld video game consoles.

sdsd: Not as glamorous as everyone else but I'm learning Neovim to manage my todolist (replacing Obsidian). My goal is to just keep it at a single page, since instead of having power, a todo list really benefits from simplicity.

YesBox: Thanks :)I'll be looking into porting during early access. I've heard the game runs on Linux with a compatibility layer though.I do everything except the pixel art and buildings. It is a crazy amount of work!

CURitterbeck: I'm currently researching how I transfer my risk management skills from traditional finance into decentralized finance. I'd like to put decentralized finance on a sound footing by building risk management infrastructure for it. One thing that has become apparent to me is that I have some deficiencies in my computer science skills. As a result, I've enrolled in a Masters of Science in Computer Science from CU Boulder through Coursera to remedy those deficiencies.

joelcares: After more than a decade of developing various websites under the brand https:&#x2F;&#x2F;anoa.ca I am pivoting the brand entirely to a creative niche: portfolio websites for the film industry. I created a new, general brand for the rest of my front end development work: https:&#x2F;&#x2F;lodewell.coIt feels like a small change, but it really makes sense in my brain and I'm glad I finally made it happen. My services feel properly positioned under these distinct brands. Now of course when I get time I need to redesign both of my own websites.Ideas wise... I like the static website world. I use 11ty, but there are others moving in this direction. Clean, performant, simple html &#x2F; css &#x2F; js websites that should last for decades. I like the idea of publishing them to IPFS, creating an indie web with some permanence to it.

ramyar: I made a simple headless todo list to use it personally and within the team. Beside simple api surface I also implemented MCP and already been able to use it inside my AI editors. Ping me if you like to give it a try!

remus: Nothing revolutionary, but there is a small organisation called The Himalayan Database [1] who have recorded (in great detail) climbing expeditions to peaks in the area. The data is available in a downloadable format, but it is a little awkward to browse. I have been working in collaboration with them to build a website for making the database more accessible https:&#x2F;&#x2F;himalayan-database.climbing-history.org&#x2F;[1] https:&#x2F;&#x2F;www.himalayandatabase.com&#x2F;

swsieber: I'm writing a print farm manager for my wife, who has 8 bambu printers. I've put one of them in lan mode for testing, but I'm pretty close to replicating the important handy (Bambu's cloud app) features, at which point I'll be able to start adding the really nice.She sells a product with 16 different printed parts, and she prints the parts in bulk batches across 7 different pause points, some of which have pause points for embedding magnets.The idea is to integrate inventory management and print scheduling into the tool, which will be nice.I have working so far: * Pulling camera images * Pulling the currently printing file, including the preview image (rendered in bambu studio and bundled with the print; standard for bambu studio), and the pause points * A dashboard with projected timing information * Notifications about jobs starting, stopping & pausing * Remote printer controlNext on the list: * Delayed printing - schedule a print to start in the night. Mostly useful so that if there's a pause point we don't leave a print paused for hours on end. * Print queueing - manually build a list of prints so that after switching plates we can just "next print" for a printer * Print scheduling - select a quantity of print files or groups of files to print, and have it schedule the prints, including projected switch times, to maximize printer utilization by avoiding jobs ending at night * Tracking magnet & filament usage, and integrating BoM and production quantity tracking.I've been mostly AI coding this, but I've go in to make it extract out components, etc. And I lay down and enforce the DB schema. I've had to ask it to back out a few things entirely. And I've had to give it the Bambu API docs I found github. But it's been going pretty well.

tndata: I'm building a proxy that sits between Claude Code and the model to visualize the full interaction loop.

esperent: I was going to say in my earlier comment that I probably didn't like it because it sounds like Uruk Hai, and the person in the comment below also said it. So safe to.say that's what most of your users will also think of. "Large ugly orc" is a terrible word association for an app even if you personally like it.Have you tried searching for meaningful words in other languages? Kagi means key in Japanese, for example. I've had luck with this approach before.

BrunoBernardino: Thanks for the suggestion. We did try but came up empty so far. I also didn't know that about Kagi!

creehappus: Recently, a simple desktop app for ingesting opentelemetry to help with other projects. This way, I dont need to set up another service just for that.

numbers: I was using Wisper Flow and had a pretty bad experience with their support related to billing and so I started building my own version of a speech to text app, it's very doable with Parakeet and Whisper models available now. I've got the app working on mac and it's been so much easier to make progress on it with AI available now.I'm not sure I'll be putting it out there because it feels like there's already 100s of these apps out there so I don't feel strongly about it.

jaredwiener: Thank you -- yes, the non-signed in front page needs some work. There's a lot of flood warnings, but if you choose topics with an account it should be a better experience.And thank you for flagging the scroll thing. I hadn't seen it, but will check.

matty22: Stained Glass Atlas (https:&#x2F;&#x2F;stainedglassatlas.com&#x2F;) - working on mapping&#x2F;documenting as much of the publicly accessible stained glass as possible. No fancy tech (vanilla HTML&#x2F;CSS&#x2F;JS). Anyone who knows of great stained glass in their local area is welcome to come add to the data set!

jaredwiener: AI isn't really the draw, it's more of a tool that helps on the backend.That said, it's both combining various updates into a cohesive timeline of a story, writing the summaries, and assigning it an urgency level which helps in sorting and some other tasks.

overtaxed: https:&#x2F;&#x2F;hooptime-vbn5prc4.manus.space&#x2F;

kristjan: I've wanted to read some long-form RSS feeds from the beginning, and friends had use cases for feed filtering, so I built https:&#x2F;&#x2F;sponder.app.The filtering was easy, but RSS doesn't do "from the beginning" (RFC 5005 exists, but is mostly unused), so scope crept into a webpage-to-RSS tool that lets me convert favorite.site&#x2F;s&#x2F;archive - autodetection of the article structure was a fun side quest.The whole thing is a little function engine (Yahoo Pipes called), so the final goal is `merge(archive, live_feed) | drip(N items per D days)` to have the archive transition seamlessly into current content. I expect I can push that live tomorrow or so.And of course Podcasts are just RSS, so hey, let's skip reruns. That's doable with filters on the episode description, but with history in place I'll add title similarity checking. I'm trying to think how to recognize cross-promoted episodes too, without having to crawl every podcast.Importantly, Sponder's _not_ a client. There are enough clients, any many are great. Each implements some subset of features, so Sponder's an intermediary that consumes and publishes pure RSS for us to use anywhere we want.Project two started over the weekend and is the NYTimes' Pips, but colors. You're building a stained glass window with regional constraints, and the big difference from using dominos is colors can mix. Also, triangles! The engine works, and I'm designing the tutorial and first handful of puzzles now.

z500: I've been taking a look at my sound change applier again. I've been trying to add syllable detection to it so that I can match directly on syllable boundaries instead of having to match on them explicitly in my sound change rules.So I started by adding the ability to define syllable structure in the rules file, then I tried running the syllable rule through the same compiler I used for the regular sound change rules. It ended up being even slower than I was anticipating, so I decided to skip the NFA to DFA conversion step and wrote a backtracking NFA runner. This worked _okay_, but if the syllable rule isn't able to fully match a word it ends up backtracking forever, and I never managed to figure out how to fix that.Last year I read a post about parser combinations and I decided to rewrite the syllable detector. I finished the rewrite and then ran into an error and gave up. This last weekend I revisited it and it turned out it was just user error again; my syllable definition rule had a mistake, but thankfully the error was a lot easier to fix with the new design. Now it emits a warning, and I'm rewriting my sample sound changes rules to use the new boundary markers and hammering out any issues, which are a lot less than I was afraid of.I'm thinking about rewriting the sound change rule compiler to use the same combinators I did for the syllable rules, but it would be kind of a shame after all the work I put into the DFA compiler lolhttps:&#x2F;&#x2F;github.com&#x2F;marriola&#x2F;Transmute

milind-soni: jsonmaps.dev its a way to create maps and create storytelling maps that you can embed in your react application, I was quite tired of how AI wasn't able to generate reliable maps in my applications.Every map library has its own imperative API and the AI output was always broken, hallucinated, or unmaintainable with so many different formats that you can put on the map.The story map part came out of wanting to build Mapbox-style scrollytelling easily. You define chapters with a camera view and content, and it handles the scroll-driven camera interpolation.Stack: MapLibre under the hood, React, published as an npm package.https:&#x2F;&#x2F;jsonmaps.dev&#x2F;

jonnycoder: That's pretty cool. I'm working in maplibre myself and your json maps seems like it could also be used to demo a workflow or tutorial in a mapping product.

paulhebert: Thanks!

paulhebert: That’s awesome, thanks!Bracket City is great! Definitely one of my favorites

wisemang: So the tree data itself mainly comes from municipal open data, just like yours does. Street Trees datasets are pretty common across cities. I just added SF yesterday after replying here :)Otherwise the map tiles are coming from OpenFreeMap [1] which are indeed based on OSM.[1] https:&#x2F;&#x2F;openfreemap.org

rahimnathwani: The ones I created so far had some characters from existing books and movies, and I don't want to take my chances with how 'fair use' is interpreted.

andsoitis: I see. Did your kid enjoy them?One downside is there’s no community for him around the books, but maybe that’s not a big deal.

rahimnathwani: They were good enough that he finished reading them once, but they were not good enough that he would recommend them or re-read them.

jmole: Any chance you'll release on macOS&#x2F;Linux?

fgdhtt: Nothing about learning in Duolingo that tartaruga means turtle but I don’t need that word in my vocabulary for now… was curious how easy it is to vibe code my own Portuguese learning app. Worked out great: I can add my own words and customize the topics. It’s using Gemini api, Google TTS + STT api, all in the browser with local storage. I’m very happy with it and it’s (almost) for free.

jayteedee: Update. I didn't expect my parents to enjoy playing the game. Apparently, they are aware that they are falling for AI videos and don't like it. And there are a lot of entertaining videos to keep them engaged and easy to spot "give me's" to keep the frustration level down.

jsattler: https:&#x2F;&#x2F;github.com&#x2F;jsattler&#x2F;BetterCaptureI'm building a lightweight screen recorder for macOS. It supports lots of features you'd expect from a professional screen recorder such as ProRes 422&#x2F;4444, HEVC&#x2F;H.265, and H.264, capturing alpha channels and supports HDR. Frame rates from 24 to 120fps. Can capture system audio and mic simultaneously. You can also exclude specific things from recordings, like the menu bar, dock, or wallpaper.No tracking, no analytics, no cloud uploads, no account. MIT licensed. Everything stays on your Mac. Still early, but happy to hear feedback!

latenightcoding: what filters are you using to find the papers, anyone you enjoyed&#x2F;recommend?

kodablah: Duralade - a programming language for durable execution (but has many neat aspects)Most of the work as of today is in a branch, can see the language spec at https:&#x2F;&#x2F;github.com&#x2F;cretz&#x2F;duralade&#x2F;blob&#x2F;initial-runtime&#x2F;docs&#x2F;..., and some samples at https:&#x2F;&#x2F;github.com&#x2F;cretz&#x2F;duralade&#x2F;tree&#x2F;initial-runtime&#x2F;sampl....May not amount to anything, but the ideas&#x2F;concepts of this durable language are quite nice.

jedberg: I'm curious what advantages this has over adding durability to an existing language, like DBOS does:https:&#x2F;&#x2F;github.com&#x2F;dbos-inc&#x2F;dbos-demo-apps&#x2F;blob&#x2F;main&#x2F;python&#x2F;...

kodablah: It's not safe enough nor is it very amenable to versioning, serialization, resumption, etc. It makes sense for modern durable execution engines to meet developers where they are (I wrote multiple of the SDKs at Temporal, including the Python one), but a purpose-built language that has serialization, patching, wait conditions, kwargs everywhere, externalizing side effects, etc, etc, etc is a big win vs something like Python.

hephaes7us: I'm making a "Podcast Search Engine", partially as an excuse to play with Elixir and Phoenix&#x2F;LiveView.It's basically just a frontend to a semantic search system, and is a tangent while I explore "knowledgebase" concepts.I'm extremely interested in knowledgebases at the moment.

reedlaw: Do you have examples of the task maturation cycle? I'm not sure how it would work for tasks like extracting structured data from images. It seems it could only work for tasks that can be scripted and wouldn't work well for tasks that need individual reasoning in every instance.

ksri: I am working on a declarative CLI for google docs&#x2F;sheets&#x2F;slides etc. The general idea is a "pull" command that converts the proprietary document into a local files like tsv or xml. The agent (claude code) then simply edits these files in place and calls "push". The library then figures out the diff and applies only the diff, taking care to preserve formatting and comments.The hypothesis is that llms are better off getting the "big picture" by reading local files. They can then spend tokens to edit the document as per the business needs rather than spending tokens to figure out how to edit the document.Another aspect is the security model. Extrasuite assigns a permission-less service account per employee. The agent gets this service account to make API calls. This means the agent only gets access to documents explicitly shared with it, and any changes it makes show up in version history separate from the user's changes.Early release can be found over here - https:&#x2F;&#x2F;github.com&#x2F;think41&#x2F;extrasuite.

mbreese: It's really a good idea. I've spend a little time on the sidelines as a coach (and parent and ref, but that's another story) and one thing that I think is crazy is the differences in what you think you can affect, and what you really can affect from the sideline. The technical area is a really small facet on the larger game, so I think your idea would make for a fun game. And knowing how much time my son spends playing Football Manager, I think there's an audience for it!
