My first stab at running a git server was Gitlab CE (because I was using it at work.) I tried running it on an Atom based server with insufficient RAM and it just crawled. Page loads just timed out. I switched to Gitea and it was a breath of fresh air.
Forgejo got to my attention when Fedora chose it for their repo server. My needs are pretty simple - just some centralized file storage of notes and some source code. I've tested a migration from Gitea 1.21 to Forgejo 9 and it was frictionless.
I'm seriously consider migrating, but I still wonder which will be better supported (and suitable for free-as-in-beer use) in the long run.
