Hangar

Self-hosted object storage in Go. Content-addressed chunks (blake3 + zstd) on Pebble, served via Fiber. Native HTTP API and S3-compatible API on the same storage.

Full documentation: hangar.mth.lc

Single-node or cluster mode. Cluster mode (HRW chunk placement RF=2 or Reed-Solomon k+m, key-sharded metadata, replicated system state, WAL catchup, anti-entropy, seed-based dynamic membership, zone-aware placement, deep-scrub, secret rotation, optional dRPC TLS) is beta — see hangar.mth.lc.

Quickstart

make build
./bin/hangar server -c config.toml

A default config.toml is generated on first start. The HTTP API binds to :8080; the S3 API is disabled by default — enable it in [s3].
