otterley: So use S3.

jockm: While not obvious from the article, it appears that they want something S3 like, but isn’t from Amazon, and possibly want to self host it. The article could be much more clear about the goals

larrymcp: Ah, thanks. Yeah I was confused because in his long list of vendors he didn't mention Wasabi, Backblaze etc. It appears that I do not know the context of his post.

panarky: Sounds like you want S4. Super simple storage service.

scottfits: 100% - i really wanted Render to add this, feels like there is potential for a startup here

CobrastanJorji: This is an interesting write up, but I'm curious about the use case. If you don't need to scale, and you don't need to replicate anything, what do you want S3? Are you using a tool that wants to write to something S3-like? Do you just like reading and writing objects via HTTP POST and GET? Are you moving an app to or from the cloud?

moondev: microceph is pretty nice and straightforward for throwaway s3 endpointshttps://canonical-microceph.readthedocs-hosted.com/stable/tu...

coredog64: Has anyone that has set up microceph determined the overhead of the required multiple OSDs? The docs make it sound scary, but it's not clear if that's because people run it on a Pi with an sdcard for block storage or because someone once ran 18TB of OSDs in production that then fell over.

jauntywundrkind: I do continue to be impressed/ over-awed by how effectively scared the Ceph docs are about just how many system resources you need. To run a mid tier not that fast storage cluster. Bother.Impressive as hell software and I am so glad to have it. But man! The insistence on mountains of ram per TB, on massive IO is intimidating.

uroni: I made https://github.com/uroni/hs5 -- focus is on single node and high performance. So plenty of alternatives available.

jerf: I think we get a "S3 clone" about once every week or two on the Golang reddit.It strikes me as a classic case of "we need all the interested people to pull in one project, not each start their own". AI may have made this worse then ever.

CobrastanJorji: I think it's like NES emulators. It's not that anyone needs one more. It's just that they're fun to make.

mickael-kerjean: I'm the author of Filestash, one of the projects listed. Our approach is quite unique in that we don't own your storage, you do, Filestash is just a proxy. You point it at whatever storage you already have (SFTP, FTP, WebDAV, Azure, SMB, IPFS, NFS, another S3 etc.), generate S3 keys bound to a specific backend and path, and it proxies everything through.

colechristensen: I want my application servers to be stateless and I've got state to keep that looks a lot more like files than database rows.And I want things like backup, replication, scaling, etc. to be generic.I wrote a git library implementation that uses S3 to store repositories for example.

tptacek: It's probably the most important storage API in the industry. Implementing it gives you on-prem storage, AWS S3 (the Hoover Dam of Internet storage megaprojects, arguably the most reliable store of any kind available to any normal programmer), and a whole ecosystem of S3-compatible options with different features and price points.It's a little like asking why you'd use SQL.

CobrastanJorji: The S3 standard is certainly really important. It's perhaps the most important web standard without any sort of standards organization or formal spec (seriously, Amazon, I'm begging you to open up to ISO or IEC or SNIA or somebody).And SQL is also very important. And yet, if somebody said "I need to store data, but it's not relational, and I just need 1000 rows, what's the best SQL solution," I would still ask why exactly they needed SQL. The might have a good reason (for example, SQLite can be a weirdly good way to persist application data), but I don't know it yet. That's why I asked.

jeroenhd: I'm pretty sure I set up most of what "Simple S3" using with Apache2 and WebDAV at least fifteen years ago.Every month there's a post of "I just want a simple S3 server" and every single one of them has a different definition of "simple". The moment any project overlaps between the use cases of two "simple S3" projects, they're no longer "simple" enough.That's probably why hosted S3-like services will exist even if writing "simple" S3 servers is so easy. Everyone has a different opinion of what basic S3 usage is like and only the large providers/startups with business licensing can afford to set up a system that supports all of them.

ChromaticPanic: Garage "unnecessarily complex" . If anything it's the simplest solution in the list especially compared to Ceph or Apache Ozone

leosanchez: Tried setting up rustfs today. It was easier that garagehq and it even comes with UI.

evil-olive: RustFS is the poster child in my mind for the worst kind of vibe-coded slop. it might be "simple" but it's not something I would ever trust with persistent data.last year they had a security vulnerability where they allowed a hardcoded "rustfs rpc" token to bypass all authentication [0]and even worse, if you read the resulting reddit thread [1] someone tracked down the culprit commits - it was introduced in July [2] and not even reviewed by another human before being merged.then the fix 6 months later [3] mentions fixing a different security vulnerability, and seemingly only fixed the hardcoded token vulnerability by accident. that PR was also only reviewed by an LLM, not a human.0: https://github.com/rustfs/rustfs/security/advisories/GHSA-h9...1: https://www.reddit.com/r/selfhosted/comments/1q432iz/update_...2: https://github.com/rustfs/rustfs/pull/163/3: https://github.com/rustfs/rustfs/pull/1291

nikeee: I am building an S3 client [1] where I have a test matrix that tests against common S3 implementations, including RustFS.That test matrix uncovered that post policies were only checked for exsitence and a valid signature, not if the request actually conforms to the signed policy. That was an arbitrary object write resulting in CVE-2026-27607 [2].In the very first issue for this bug, it seemed that the authors of the S3 implementation didn't know the difference between the content-length of GetObject and content-length-range of a PostObject. That was kind of a bummer and leads me to advise all my friends not to use rustfs, though I like what they are doing in principal (building a Minio alternative).[1]: https://github.com/nikeee/lean-s3 [2]: https://github.com/rustfs/rustfs/security/advisories/GHSA-w5... [3]: https://github.com/rustfs/rustfs/issues/984

PunchyHamster: I recently submitted bug about how their own docs tell you to* create rustfs user * run the rustfs from root via systemd, but with bunch of privileges removed * write logs into /var/logs/ instead of /var/logLooks like someone told some LLM to make docs about running it as service and never looked at output

PunchyHamster: S3 isn't "simple" tho.It doesn't need to care about POSIX mess but there is whole swathes of features many implementations miss or are incomplete, both on frontend side (serving files with right headers, or with right authentication) and backend (user/policy management, legal hold, versioning etc.)It gets even more messy when migrating, for example migrating your backups to garagefs will lose you versioning, which means that if your S3 secret used to write backups gets compromised, your backups are gone vs on implementation that supports versioning you can just rollback.Similarly with password, some will give you secret and login but won't allow setting your own so you'd have to re-key every device using it, some will allow import, but only in certain format so you can restore from backup, bot not migrate from other software.

ovaistariq: or Tigris

ovaistariq: Potential of startup for hosted object storage? I think Tigris (https://www.tigrisdata.com/docs/) will work pretty well with Render.

jgalt212: S3 with tree-shaking. i.e. specify the features you need, out comes an executable for that subset of S3 features you desire.Or like lodash custom builds.https://lodash.com/custom-builds

nhumrich: Well, OP, your requirements section is seriously lacking. You need "s3", but only local, non horizontally scalable?You failed to answer why you even need s3... Why not a filesystem? Full stop. The entire point of s3 is distributed.

hybirdss: someone is 100% going to write the 'i just want simple S4' post next month

keyle: I just need something that can do S3 and is reliable and not slow. Oh, simply that.I'm a simple man, I just need edge delivered cdn content that never fails and responds within 20ms.

pkghost: Based on the list of contenders feels like you might be missing rsync.net?

mickael-kerjean: By itself rsync.net doesn't support S3. The one I wrote (Filestash) lets you use rsync.net as a downstream storage and proxies it through the S3 protocol.

didgetmaster: Better title: I just want local storage with a simple S3 interface.

singhrac: I wanted to try NVIDIA’s aistore for our datasets, but I couldn’t figure out how to get a small version up and running so I gave up (a few years ago, today I’d get an LLM to show me how k8s works).

JBorrow: People write applications that work with the S3 API but may want to host their own storage for a variety of reasons. Personally I make use of S3-compatible services for pre-signed url access to data on disks I own. The distributed aspect is only one reason why someone might want an S3-like service.

a_t48: They're certainly a rabbit hole, too.

estebarb: Personally I would suggest that the "easiest S3" would be simply using NFS. You can get replication with RAID.S3 is simple for the users, not the operators. For replicating something like S3 you need to manage a lot of parts and take a lot of decisions. The design space is huge:Replication: RAID, distributed copies, distributed erasure codes...Coordination: centralized, centralized with backup, decentralized, logic in client...How to handle huge files: nope, client concats them, a coordinator node concats them...How will be the network: local networking, wan, a mix. Slow or fast?Nature of storage: 24/7 or sporadically connected.How to handle network partitions, pick CAP sides...Just for instance: network topology. In your own DC you may say each connection has the same cost. In AWS you may want connections to stay in the same AZ, use certain IPs for certain source-destination to leverage cheaper prices and so on...

0xbadcafebee: [delayed]

klodolph: NFS in practice is too different from S3 to make this work.I’ve been at a couple companies where somebody tried putting an S3 interface in front of an NFS cluster. In practice, the semantics of S3 and NFS are different enough that I’ve had to then deal with software failures. Software designed to work with S3 is designed to work with S3 semantics and S3 performance. Hook it up to an S3 API on what is otherwise an NFS server and you can get problems.“You can get replication with RAID” is technically true, but it’s just not good enough in most NFS systems. S3 style replication keeps files available in spite of multiple node failures.The problems I’m talking about arise because when you use an S3-compatible API on your NFS system, it’s often true that you’re rolling the dice with three different vendors—you have the storage appliance vendor, you have the vendor for the software talking to S3, and you have Amazon who wrote the S3 client libraries. It’s kind of a nightmare of compatibility problems in my experience.

sudb: or cloudflare R2 for that matter (very useful for egress-heavy workloads for which it is ~free)

jppope: I was curious why this didn't come up in the article

TheDong: > It strikes me as a classic case of "we need all the interested people to pull in one project, not each start their own".And every few weeks in the cooking subreddit we get a new person talking about a new soup they made. Just think if we put all 1000 of those cooks in one kitchen with one pot, we'd end up with the best soup in the world.Anyway, we already have "the one" project everyone can coalesce on, we have CephFS. If all the redditors actually hopped into one project, it would end up as an even more complex difficult to manage mess I believe.

tptacek: Since this has come up 4-5 times on the thread already, the clear subtext of this post is that this developer wants to build to the S3 API, but run their storage locally --- maybe for testing reasons, maybe for data hygiene reasons, maybe for performance reasons. So things like "what about Hugging Face's object storage product" don't really answer their question.

skywhopper: I wouldn’t say it’s “clear”. If you want good answers to your Internet blog begs, it’s probably good to actually state your use case. “I just want S3” means different things to different people.

rtpg: Is the problem here that everyone wants a different like 45% of the S3 API? Or is it that minio sucked all the oxygen out of the air in this space by being good at this, and now we need something else to show up?

deepsun: Then why nobody forked minio?

K0IN: Not that long ago someone on hn poster this [0] a zig based s3 server in 1k lines, (warning not production ready) but if you really look for something simple, it might fit your case.[0] https://news.ycombinator.com/item?id=46421196

pveierland: Garage has worked well for me and gives a good sense of stability. They provide helm charts for deployment and a CLI. There's also very few concepts to learn to start to use it, while e.g. for SeaweedFS I feel like you need to parse a lot of docs and understand more specific terminology.

themafia: > but it’s just not good enough in most NFS systems.NFS is just an interface. At the end of the day it's on top of an FS. It's entirely possible and sometimes done in practice to replicate the underlying store served by NFS. As you would expect there are several means of doing this from the simple to the truly "high-availability."

jdbohrman: Wouldn't Blossom fit this? https://github.com/hzrd149/blossom

convolvatron: I just spent some time with the s3 protocol and I agree completely. What should have been able to leverage the simplifying assumptions turned into another hodgepodge. It’s not like nfs is a real shining example of simplicity either. I’ve never worked with p9, but potentially that aside I think we really failed to come up with a decent distributed file model,

jen20: It was simple(ish) 20 years ago, to be fair.

thayne: I don't think that is what they are looking for. They just want something with an s3 compatible API they can run on their local network or maybe even on the same host.

sandreas: [delayed]

bosky101: If anyone wants an s3 browser with folder counts, and object rendering based on its extension, dm.

thayne: Simpler than it is now, but the authentication system was never simple. You can't just put a bearer token in the authorization header, you have to follow a complicated algorithm to sign the request. That made some sense 20 years ago when s3 didn't use tls to protect against a mitm that changed the changed the request. It is less valuable now when you use tls.

tehlike: vibe code a s3 implementation build on tikv.

crote: Isn't the whole signed request part a hard requirement for 3rd party access? S3 was originally designed for web use, which means giving not-fully-trusted browsers some access to your storage bucket.You can't exactly do "this client is allowed to download this one specific file for the next 24 hours (but not use it like their personal CDN and share the link with everyone)" or "this client is allowed to upload a single image file up to 10MB (but not upload a 100GB copy of Friends)" with basic bearer tokens.

eddythompson80: Of course you can do all that with a basic bearer token. It’s just a signed json object with an expiration

boulos: Yeah, but that missing context is super important.If they want it for local dev work, that's pretty different from wanting a high-performance air gapped object store without rewriting clients.They seem to know what they're doing (having complained about a methodology problem in MinIO), and yet don't personally want to throw their hat in the ring not maybe pay anyone...Context matters!

teekert: Fwiw, yesterday I was messing about with GitLab backups. One of the options for direct off-site is S3. But I want that S3 bucket to live on a box on my own Tailnet.So I too just want simple S3. Minio used to be the no-brainer. I'll checkout RustFS as well.It does not sound hard (although it is hard for me!). It sounds like it should be some LinuxServer io container. Doesn't it? At this point S3 is just as standard as WebDav or anything right?

LunicLynx: Simple S3 sooooooo S4 ? xD

grizzletooth: Check out Floci. It is a self hosted AWS clone with multiple services functional, including S3 and Dynamodb.https://github.com/floci-io/floci

evil-olive: Floci is yet more AI slop."firt commit" [0] was less than a month ago and added 51k lines in a single commit.0: https://github.com/floci-io/floci/commit/61433f59ab995e9eaeb...

patates: S3 needs a split:QS3 (Quite Simple Storage Service) for the barebones. Bucket/Object CRUD. Maybe: Multipart Uploads. Presigned URLs.S3 for Object Tagging, Access Control Lists, etc.S3E (enterprise? extended? elaborate?) for Object Lock & Retention (WORM compliance, Legal Holds), Event Notifications and so on.

syabro: what's the point then? Just api around FS?

mrweasel: For a lot of project that would be sufficient. I've worked on projects that "required" an S3 storage solution. Not because it actually did, but because it needed some sort of object/file storage which could be accesses from somewhere, might be a Java application running in JBoss, might be a SpringBoot application in a container, on Kubernetes, Nomad or just on a VM.Like it or not, S3 has become the de facto API for object storage for many developers. From the operations side of things, managing files is easier and already taken care of by your storage solution, be it a SAN, NAS or something entirely different. Being able to backup and manage whatever is stored in S3 with your existing setup is direct saving.If you actually use a large subset of S3s features this might not be good solution, but in my experience you have a few buckets and a few limited ACLs and that's it.

ilian: How about s3proxy: https://github.com/gaul/s3proxy Among other things, it can serve local folders as s3 api.

runlevel1: `rclone serve s3` is actually a thin wrapper around this: https://github.com/rclone/gofakes3That repo is a fork of this project: https://github.com/johannesboyne/gofakes3They bill it as being for testing, but it works great if all you want is a no-fuss S3-compatible API on top of a filesystem. I've run it on my NAS for a few years now to provide a much faster transfer protocol compared to SMB.

justincormack: I am writing an s3 server, just checked, have detailed tests for content-length-range. I found that Ceph was the only open source implementation with decent tests, and I ported these as my first stages of implementation, although I have since added a lot more. Notionally rustfs say they use the ceph test suite, but not sure how often and completely, they certainly had big conformance gaps.

KaiserPro: The author is also not really clear on what they are actually needing.If they just want webfile interface then a webserver with simple auth and webDAV would work more than well enough.The problem is that they then go onto talk about lots of projects that all have posix interfaces. Which is slap bang into shared filesystem land.S3 is not a filesystem, and nothing shows that more than when you use it as an object store _for_ a filesystem.Depending on the access requirements, if you're doing local to local, then NFSv4 is probably more than enough. Unless you care about file locking (unlucky, you're in shit now)

KaiserPro: but why would you ever want to run ceph? its just such a huge monster.Its also not that useful even if you have enough machines to run it properly.NVME and zfs is fast enough for virtually anything now. With snapshot and snapshot sending you get decent backups for half the hardware cost of ceph.

KaiserPro: Why would you use S3 on top of NFS?I mean you can, it would simplfy the locking somewhat.But if you are doing file sharing for apps inside a network you manage, just use NFS, and maybe worry about the locking later.

bombcar: It's like "Word/Excel is too bloated, I just need a simple subset!" and each simple subset is subtly different.

Havoc: I did exactly that. 15 mins for initial implementation was about right. And it seemed fine at first glance.Then I decided to run the Ceph S3 test suite against it. So many issues. Think it passed 3 tests on first run out of I think about a hundred. Took another couple of hours to get it to a state that is even vaguely passable for non production use.Got something vaguely workable but even after many hours I can’t say I super trust it> implementation can't be that complicated.S3 has a fair bit of bloat in spec that nobody seems to use and it’s not clearly delineated which is core and what’s ahem optional. I ended up relying on the LLM to figure out what’s core and that ended up missing stuff too so that needed a couple of feature iterations too

ferdzo: I wanted the same, so I made my own. Initially I started it without vibe coding, but as I wanted to add more features than the initial working S3 API, I decided it's not worth the time to not vibe simple API stuff. I use it for backups, for a Minio replacement in a Milvus database and other random stuff. Not bad for a week work. It's single node so far and not meant for distributed computing.https://github.com/ferdzo/fs

matzie: +1 for s3 proxy! I use it on docker for my dev env, is so simple and works well

barelysapient: Unlike the author, I run SeaweedFS without issue locally and with acceptable transfer speeds.

bombcar: If all the "popular" solutions are complex, it means the problem domain is complex.You either are doomed to reimplement and rediscover the complexity on your own, or you change your requirements to fit a narrower problem domain to avoid (some of) the complexity.

convolvatron: I'm working on a distributed S3 cache that supports just two functions, pread style contents of a file and all the elements in a directory. I've worked on other systems that represents this entire structure as RDF triples, which leaves you with just query and insert. To come at it from another direction EFS only implements about 2/3 of NFSv4, and S3 was perfectly functional before they larded it up with all this policy stuff.I'm not saying that there weren't reasons to add these functions to the protocol, but if your aim is minimalism, then you can do _much_ better, and I think there is a real benefit in having a bare bones protocol that anyone could implement in many contexts.

jen20: > a complicated algorithm to sign the request.There are lots of benefits to this over the bearer token approach that many take. Binding the authentication to the specific request is valuable regardless of TLS.

Frannky: Self hosted minio?

skrtskrt: At this point S3 is an API spec more than a particular system. Plenty of things only work against the S3 API spec since the implementations have become such popular and relatively cheap and performant storage systems. It gives a nice limited surface area that doesn't allow you to do things that can get too complex or can vary too much across filesystems, etc.

nitwit005: It feels like there is more missing context than that:> I just want S3. My needs are pretty basic. I don't need to scale out. I don't need replication. I just need something that can do S3 and is reliable and not slow.What does reliable mean, without replication, and no mention of backups?

iExalt: Proposal to rename the services:* S4: Stupid/Silly Simple Storage Service* S3: Simple Storage Service* S2: Storage Service

bluefirebrand: You can't have the numbers go down like this. Try pitching S2 to your project manager. You will be told 100% "Why not use S4 instead, that sounds better"
