"doesn't support: ... Web UI."
So, it's a git server with an interesting storage layer? Don't get me wrong, that part sounds like it might have been a ton of work to implement, but I think the web UI (pull requests, etc) is a lot of what Github has won on historically.
Basically I don't feel qualified to judge the product itself, but I think positioning it against Github, while popular given the recent hard times, isn't quite correct.

"Doesn't" doesn't mean "can't". Someone just needs to do the work (with no thanks or pay expected).
edit: the perspective of open source projects has really changed in the last 10 years, from collaboration to nice personal projects now being referred to as "the product".
