Federation status: See here!
Vervis is a work-in-progress federated project and repository hosting and collaboration platform. Its development is meant to help form the ForgeFed specification for project hosting platform federation, and hopefully get existing platforms (such as Gitea, Gogs, GitLab CE, etc.) to support it.
Vervis is being used for its own development: Vervis project page
