Walgit is a Git server that simplifies repository hosting by using a single binary and an object store, such as S3 or GCS, eliminating the need for a database, leader, or local state. This approach allows for scalable and disposable servers, where multiple machines can serve the same repositories consistently without coordination, and losing a machine only results in temporary downtime. Walgit's design addresses the challenges of hosting large Git repositories, particularly with regards to packfiles, which can cause performance issues over network filesystems, and provides features such as smart HTTP, Git LFS, and a browsing web UI, making it a viable solution for large-scale Git hosting.
