I'm probably preaching to the choir here, but there absolutely _needs_ to be a federated version of GitHub/GitLab.

Let me host my projects' critical infrastructure (issue tracker, PRs, private repos etc) on my own servers, while also being able to interact and socialize with the rest of the open source world.

I'll keep saying this until someone builds it - I would do it myself if I had enough time on my hands right now.
