Just migrate to Forgejo/Codeberg[1][2] or SourceHut[3]. Both are like a light speed compared to GitHub and GitLab.
replies(2):
Pushes and pulls would still kinda work, actions not so much (but that's cause it needed to transfer more then 100MB)
Sourcehut is basically a really barebones web interface for git server, so I don't think it's really comparable to GitHub
For hosting your own projects that's sometimes not a viable solution either. Limiting your open source project to platform other than GitHub hurts it's discoverability, because usually GitHub is what most devs and non devs associate with open source. I heard a lot of "It's not open source if it's not on GitHub". You can mirror your project to GH of course
"Just migrate to X because it's faster" doesn't work that well in the real world
