I think Anthropic should buy Github after buying bun and everything in between.
If you don't want to self-host Gitea/Forgejo, I recommend SourceHut for private repos and Codeberg for public ones. Happy to answer any questions you might have for either based on my experience!
I commented on the other post, but GHA's awful reliability, ergonomics and performance have caused me to quit my job and work on https://harmont.dev.
Other post: GitHub Actions down again today [0]
Technically this one was earlier but the other one has more traction.
Over the last 90 days the status page (https://www.githubstatus.com/) shows around 2 nines of uptime for most services.
Apparently they deleted the Github Actions account as it shows up as ghost in PR comments.
