Yup! Still haven't switched off of Github, but considering it at this point. If you're in my shoes, here's some tools we use that help:

- https://github.com/sethvargo/ratchet for pinning external Actions/Workflows to specific commit hashes

- https://www.warpbuild.com/ for much faster runners (also: runs-on/namespace/buildjet/blacksmith/depot/... take your pick)

- soon moving to Buildkite for orchestration of our CI jobs

I still just need a reasonable alternative for the "store our git repo, allow us to make and merge prs" part of things. Hopefully someone takes all the pieces that the Pierre team is publishing and makes this available soon. The Github UI and the `gh` cli are actually really nice and the existing alternative code storage tools are not great IMO.
