There could not be a more opportune time to make a competitor to GitHub, especially one grounded in community and accountability. Git was not meant to be centralized; “pull requests” are not actually an open standard and throwing code over the wall at others is not actually social coding.

@anildash have you seen @Codeberg ?

There's also self-hosting options with @forgejo - which is working on federation for workflows not directly in git itself.

These may be the kind of things you're looking for.
