RustFS

RustFS is a distributed object storage system built in Rust. Its S3-compatible API lets existing S3 applications and clients store and retrieve objects against it, with a focus on data lake, AI, and big data workloads. It can coexist with and migrate data from other S3-compatible systems.

It also speaks the OpenStack Swift API with Keystone authentication and X-Auth-Token headers, and ships a browser console for managing buckets and uploading objects. Multi-tenancy, versioning, bucket replication, event notifications, and bitrot protection are supported, and OIDC role values can be mapped into the authorization pipeline, including Microsoft Entra ID app roles.

RustFS runs as a single node or in a distributed cluster and deploys via Docker, Podman, Helm charts on Kubernetes, or a Nix flake. It is open source under the Apache 2.0 license.
