A lightweight, standalone Git LFS server written in Go that authenticates users against GitHub organisation and repository permissions.

• Full Git LFS Batch API compliance
• File locking API for coordinating concurrent edits
• GitHub-based authentication (checks pull/push permissions on your repo)
• Multiple repository endpoints from a single instance
• Local filesystem or S3-compatible object storage (AWS S3, Cloudflare R2, MinIO, etc.)
• HMAC-signed transfer URLs with configurable expiration
• SHA-256 integrity verification on upload
• Configurable per-endpoint visibility (public/private)
• Per-IP rate limiting with configurable token bucket
• Docker-first deployment

cp config.toml.example config.toml
# Edit config.toml with your endpoints, then:
docker compose up -d

# Build
make build

# Edit config.toml, then run:
./bin/anchor-lfs
