> 2026-03-02: Ruohang Feng has forked MinIO to pgsty/minio and is promising to maintain a stable, CVE-patched, distribution.
This is what I went with.
I use it in end to end tests as an S3 simulator that starts and stops instantly and reads & writes to a local directory, - as you'd expect it's great in that role. No complaints. Given the fork's maintainer puts their real name on it & stakes their reputation, you'd assume it can be trusted - but my use case is simpler than most.
I had switched some projects to SeaweedFS's Docker image. It worked well. This is good to know there is a successor open source project that would require no code changes to use. Will evaluate.
This is what I use. I had a minio instance that was replaced flawlessly with silo. This is an excellent project and needs more traction. All existing minio users must switch to Silo ASAP.
It's nice to hear about other products, but OP made it sound like Minio disappeared and was not an option. Neither are true. Yes the company moved on but the old source is sitting there and that version is pretty good as-is. We're still using it in prod, no issues for us. The old container images are floating around and you're free to copy them to wherever.
If you need support or newer features, fork it or use ^ this fork.
I use that aswell since it can be used and expose a posix filesystem. This is helpful when we want to add s3 to existing storage like a nas. (Well we had some problems with it in the past tough)
Sadly most new projects do not offer posix anymore.
I've been using it for local development for a while now. My goal was to replace MinIO, which I could run and configure with a single Docker command. VersityGW works just as well for that.

On the other hand, this means that it's bound by filesystem naming rules - e.g. you can't have an object named "abc/", or a pair of objects named "a" and "a/b".
Running Sentry on prem, I had to swap out their default SeaweedFS setup for Garage because the former kept failing under concurrent writes. I tried digging around for a bit, but found that the swap was easier and faster, Garage has also worked great for single node use cases (e.g. tested up to around 10 TB of data). I still think that SeaweedFS is a cool project, might have been a config issue or something, wasn’t worth tweaking.
The setup for Garage sucks, especially cause their Docker image doesn’t automatically create keys or buckets and permissions for you like for example various RDBMS images do. Doing that the first time manually was annoying, but their docs are pretty nice and an AI agent can build you your own Docker image with custom init in about 15 minutes.
Worst with it I’ve had were issues with hooking up WinSCP to it directly to browse saved satellite data, initial connections would hang for some reason, not sure what the problem was either.
Also used Zenko but kinda got the feeling that the project wasn’t as healthy and straight up felt abandoned (e.g. the outdated container images and such), though there is some activity.
SeaweedFS performance should be the fastest. Please create an issue if there are any performance issues with SeaweedFS, or you see it is slower than any alternatives.
Not without snapshot currently. I guess I could collect all writes in the (optional) WAL file while a backup is running, then the files would be consistent.
The title is 'for single node local S3' but what they actually mean is 'for minio-compatibility', which is an entirely different question.
When I abandoned minio a year or so ago, I also surveyed the options, and settled on Garage. It lacked the GUI, but felt about the same complexity as minio. Perhaps a smidge more complexity, as I moved to 3-node and 5-node separate instances of garage, running as containers under Nomad.
I don't recall it being onerous, but I was looking for some basic S3-alike capabilities, not just minio-alike.
(How many people set out to build an object storage system with some number of AWS S3 primitives, but primarily try to match a third-party proprietary system's foibles?)
> So, Garage does work, but gosh…it is not just a drop-in replacement in terms of code changes.
I think in terms of actual code that uses local S3, it pretty much was a drop-in replacement. (I have multiple distribution/registry, Grafana Loki / Mimir, influx3 - all backing onto my object storage system, and the config changes there were modest - key+secret, and url - just as you'd expect.)
Filestash (https://github.com/mickael-kerjean/filestash) has a s3 gateway plugin that I made. It proxy the S3 traffic to any downstream storage: SFTP, FTP, another S3, SMB, NFS, IPFS, ...
How does that handle concurrency (e.g. updates being atomic, conditional PUT) and data consistency after a crash? Getting that right over generic backends sounds challenging, to say the least.
Almost went past looking at this option, it has a far bigger ecosystem of both storage and auth plugins and otherwise looks to be more mature than I might have guessed from the passing comment.
This is what I went with.
