 **Purpose**: Gitea is a painless self-hosted all-in-one software development service, it includes Git hosting, code review, team collaboration, package registry and CI/CD. It is similar to GitHub, Bitbucket and GitLab. Gitea was forked from Gogs originally and almost all the code has been changed.
