RustFS Storage – High-performance S3-compatible object storage in Rust

Looking for a faster alternative for small-file workloads?
Want zero-downtime migrations and less operational headache?
Need a single binary that just works everywhere?

RustFS Storage is a modern, open-source, S3-compatible object store built from the ground up in Rust.

Core features

• Up to 2.3–4.1× higher throughput on objects < 256 KB compared to traditional solutions (internal benchmarks)
• Single static binary (~18 MB), no runtime dependencies, memory-safe by design
• Full S3 API compatibility – works with AWS SDKs, rclone, s3cmd, MinIO Client, Cloudflare R2, Backblaze B2, etc.
• Built-in proxy mode for seamless live migration from MinIO, Ceph or any other S3-compatible storage
• On-the-fly deduplication and compression (zstd / lz4)
• Automatic hot/cold tiering (local disks ↔ cloud archives)
• Built-in Prometheus metrics + ready Grafana dashboards
• Multi-tenancy, bucket policies and versioning out of the box
• Native support for Kubernetes (Helm chart), Docker, Fly.io, Railway, and bare metal

Perfect for

• Startups and indie projects that want maximum performance with minimum nodes
• Teams migrating away from heavier storage systems
• Developers who value simplicity, safety of Rust
