I’m looking forward to the Forgejo Federation to be completed.
It will be nice to not have to choose between self hosting your repository and having your repository discoverable.

Is forge federation ready to be used by developers around the world? Not yet.
But the first Forgejo release with native federation implementation based on ForgeFed and F3 is expected next year.
