OSI-licensed only · self-hostable
MinIO's community repository is licensed AGPL-3.0, but it is no longer a live project: the repository was archived by its owner on 25 April 2026, carries a notice that it is no longer maintained, and is source-only with no precompiled binaries. MinIO points users to its AIStor Free and AIStor Enterprise editions instead. If you want an actively maintained open-source S3-compatible store, these are the options.
Every tool below is under an OSI-approved licence (AGPL-3.0, Apache-2.0, LGPL), checked against its repository, and none of the repositories was archived at the time of checking.
Licences checked against each repository on November 7, 2026.
| Tool | Best for | Licence | Runs as |
|---|---|---|---|
| Garage | Small self-hosted clusters across locations | AGPL-3.0 | Server |
| SeaweedFS | Large numbers of files with an S3 API | Apache-2.0 | Server |
| RustFS | MinIO-style S3 storage in Rust | Apache-2.0 | Server |
| Ceph | Cluster-scale object, block and file storage | LGPL-2.1 OR LGPL-3.0 | Server |
| Zenko CloudServer | Node.js S3 server for development and Zenko setups | Apache-2.0 | Docker |
| Versity S3 Gateway | S3 on top of an existing filesystem | Apache-2.0 | Server |
Best for: Small self-hosted clusters across locations
An S3-compatible distributed object storage service for self-hosting at small-to-medium scale, built for nodes in different physical locations and maintained by Deuxfleurs. Hosted at git.deuxfleurs.fr.
Best for: Large numbers of files with an S3 API
A distributed storage system for object storage (S3), file systems and Iceberg tables, built to handle very large file counts with horizontal scaling.
Best for: MinIO-style S3 storage in Rust
An S3-compatible high-performance object storage system; the README marks S3 Tables and MinIO on-disk compatibility as preview features.
Best for: Cluster-scale object, block and file storage
A scalable distributed storage system providing object, block and file storage. The README says most of Ceph is dual-licensed under LGPL 2.1 or 3.0.
Best for: Node.js S3 server for development and Zenko setups
An open-source Node.js implementation of the Amazon S3 protocol, part of Scality's Zenko multi-cloud data controller.
Best for: S3 on top of an existing filesystem
A high-performance S3 translation service that converts S3 commands for storage systems; its About text calls it a simple-to-deploy S3 object storage server for your filesystem.

Quick answers to common questions
The community repository is AGPL-3.0, which is an OSI-approved licence, but it was archived on 25 April 2026 and is marked as no longer maintained, with source-only distribution.
SeaweedFS, Garage and RustFS are actively developed S3-compatible stores under AGPL-3.0 or Apache-2.0. Pick by scale and operational needs.
Its README presents it as S3-compatible with a published compatibility matrix and marks some features as preview. Test your workloads before relying on it.
Garage is built for low hardware requirements and ships as a single dependency-free binary according to its website.
For internal use, not in practice. If you modify the code and offer it to others over a network, the AGPL requires you to publish your changes.
List it on TechLogHub and we'll review it for this page.
