Gitea

Gitea is a lightweight, self-hosted Git service written in Go, offering repository hosting, issue tracking, pull requests, a built-in CI/CD runner (Gitea Actions, GitHub Actions-compatible), a package registry, and a wiki — all in a single low-resource binary. It's a popular self-hosted alternative to GitHub or GitLab for teams that want full control of their Git infrastructure without the overhead of GitLab's larger footprint. Runs comfortably on a small VPS or Raspberry Pi and supports SQLite, MySQL, and PostgreSQL as its database backend.
