Gogs is the original. Gitea is a fork because the dev of Gogs wasn’t taking community input (I think that was the reasoning behind it). Forgejo is a fork of gitea because some folks didn’t like gitea forming a for profit corporation (Or something to that effect).
As far as day to day use they’re all fairly similar, though it’s been a long time since I used Gogs.
Thanks, I knew there was a bit more to it but hadn’t followed it all that closely.
