If this looks familar to you (demo here), that’s because it’s a community managed fork of Gogs. Why the fork?

We’re a growing group of former Gogs users and contributors who found the single-maintainer management model of Gogs frustrating and thus decided to make an effort to build a more open and faster development model.

This happened back in December of 2016, so it’d be interesting to compare and contrast the progress of both projects over time. At first glance, I’d say that Gogs is keeping up quite nicely with its BDFL model. But who knows, maybe the mere existence of Gitea spurred Unknwon on toward more actively maintaining Gogs.
