This has actually been my dream for some time now. Not AP/Fediverse since that is built for social networks, but some platform that federates decentrally and functions closer to GitHub/Forgejo.

It would be an absolute dream to have a platform that lets anyone explore projects from any of the other nodes and build upon them.
