I used to work in a small independent team of 30 people within a large corp, half of which was dev. We used to run our own gitlab on-prem, our CI/CD was also on-prem. It worked perfectly, never had down time, devops guy could configure them on-demand to our needs. Me (and some other guys) also jumped in times to times to help (mostly just ssh into the servers for health check, disk partition, etc.). Then we grew (the biz team, dev was the same) and some new PMs with fancy Ivy League degrees came in and pushed for on-cloud Bitbucket. Things went to shit pretty fast after that ... Our codebase was only a few hundred thousands lines, there was only like hundreds of commits per day, the servers our git + CI/CD lived on never saturated ...

We should worry less about what everyone else uses, and more about what we use. I'm self-hosting Gitea and thinking of upgrading to Forgejo. What are you using?

My small org has definitely had internal discussions around self-hosting gitlab. We'll see what happens.

probably not. The people that have done it before or willing to do it now is probably a very % of the commit volume, they leaving wouldn't change much, probably not gonna even move the exponential growth needle.
