Gitea

A self-hosted Git service written in Go that hosts repositories next to pull requests, code review, issue tracking, wikis, releases, a package registry and its own CI runner, all inside one small binary. The interface is deliberately familiar to GitHub users, so moving a team across usually means changing the remote URL rather than relearning the workflow.

Small teams and open source projects use it to keep their source and issue history in a place they administer themselves instead of on a shared platform.

Self-hosting puts the repositories, the accounts and the CI runners on your own hardware, with no price per contributor and a backup that comes down to the database and the repository volume.
