What are some good alternatives to MinIO since it’s no longer open source?

It’s a shame what happened with MinIO; I really wish someone would take a stab at forking it and keeping it alive, especially since they stripped out some UI management features recently. I might take a closer look at Garage, but I wish it had support for object locking.

For what it’s worth, I’m using the free tier of Cloudflare R2 and it’s working out pretty well for my needs!

Ceph could be worth considering as it’s a mature alternative and usable on a single node, though it's designed for clustered environments. If you're looking for something more aligned with MinIO, RustFS seems to be a solid option. SeaweedFS might be another route you explore.

It really depends on what you need. Garage offers decent performance for basic S3-compatible storage, supporting common API operations, but it lacks many of MinIO's features and has had issues with database corruption. Alarik is still in the early stages and isn’t quite production-ready. RustFS, however, comes very close to matching MinIO in terms of features and performance. If you're worried about security or trust, the good thing is you can always check out the source code too. Alternatively, you might consider sticking with the last FOSS version of MinIO, which will continue to get critical updates.

As someone who enjoys using RustFS, I found their GitHub before they even launched their SEO-optimized site. Honestly, I wouldn't blame them for going that route; if I were making a website for a software project, I might do the same. Just goes to show how times are changing!

Actually, MinIO is still technically open source; you can grab the source on GitHub, but it’s no longer actively maintained. If anyone is keen on keeping it alive, they could always maintain a fork. There are interesting projects like Versity and RustFS, which look promising.
