Serverless Git for large files.
Crab is a serverless Git remote storage solution for teams working with models, datasets, game assets, media, and other large files. Repositories live directly in cloud object storage such as S3, Google Cloud Storage, or Azure Blob Storage, with no servers, databases, or LFS endpoints to operate.

- Bring your own bucket — store repository data in cloud storage you control.
- Keep standard Git workflows — clone, commit, push, branch, and review with familiar Git commands.
- Upload less data — content-defined chunking and deduplication send only the pieces that changed.
- Hydrate on demand — clone quickly with lightweight pointer files, then materialize the large files you actually need.
- Use a desktop app when you want one — browse repositories, preview files, hydrate or dehydrate content, diff changes, and work over SSH.
