I have moved to self-host Forgejo a few years ago and I can also highly recommend. It's working great. I have posted a tutorial [1] (verified last month that it still works), and recently moved from Hetzner to 2 Raspberry Pi's for hosting the server and the runner [2]. It's great. Really rock solid. Has been more reliable and faster than GitHub.
