Gitea lacks the ability to host static pages from Git. The Codeberg Pages Server addresses this lack by implementing a standalone service that connects to Gitea via API. It is suitable to be deployed by other Gitea instances, too, to offer static pages hosting to their users.

End user documentation can mainly be found at the Wiki and the Codeberg Documentation.

Gitea is a painless self-hosted Git service. It is similar to GitHub, Bitbucket, and GitLab. Gitea is a fork of Gogs. See the Gitea Announcement blog post to read about the justification for a fork.

Tea Runner is an application that runs on a host and carries out simple actions whenever Gitea triggers it with a webhook. It's designed with minimalism in mind. It's much less capable than Gitlab pipelines or Github actions. But on the flip side, it's far easier to configure than Jenkins or Drone.

Out of the box, Tea Runner can:

• Copy newly committed files to a remote directory.
• Build a new Docker image on a remote host.
