Shopify CEO Tobi Lütke has open-sourced walgit, a Git server that operates without a database. The architecture stores Git data directly in S3 or GCS, treating the bucket as the repository itself.
Key Features:
- Object Storage Repo: Git data lives in S3/GCS, with manifests acting as commit points.
- Disposable State: Servers are stateless caches; data remains safe even if all servers go down.
- Full Feature Set: Supports Git LFS, Smart HTTP, OIDC auth, webhooks, a React UI, and a JSON API.
- Scalable Design: S3 and CDNs can serve fresh clones directly.
While currently pre-1.0 and not a GitHub replacement, the serverless architecture offers interesting possibilities for scalability and resilience.
