Pay for pushes, not repositories.

Open-source git hosting that keeps every repository in your own S3 bucket. An idle one costs its bytes and nothing else.

Lose every server. Lose nothing.

Three servers, one bucket. None of them holds anything the bucket does not.

Your users stay in your database.

Every account lives twice. Each rename, deletion and suspension must be copied across, and every miss orphans a repository.

Agents commit without a clone.

Apache-2.0, one binary, your bucket. Any S3-compatible store works, and any number of servers can share it.
