Oddbean new post about login | logout I don't think so, maybe the about page give you a bit more information? https://gitworkshop.dev/about. @DanConwayDev is the creator/maintainer of ngit and gitworkshop so he can probably answer any other questions.
It requires a basic git server but not gitea or gitlab as all the PR functionality happens over nostr. I'm planning on releasing a basic git server implementation similar to song (or maybe fork or enhance song) that hopefully a number of people would run public instances of that would host anyone's repos no-KYC with zero setup or sign up required.
Right now the need to sort out a git server seems like the biggest friction for on boarding.
