I saw gitorious being mentioned in the comments and want to second that. The article missing that gitorious was the sleeker looking and most promising second contender after github until it was aquired and shutdown by gitlab seems odd. It still baffles me that gitlab never managed to make their product look or feel even half decent. Whoever will challenge github will look and feel more human and more like home not less.
IMO, the Gitlab interface is better than github for most of the actual code features. Github still doesn't have a graphical tree view of the commit history. Hell, even the git CLI has that.
The only thing I like better about Github is the dashboard for managing MR's/issues/notifications. Gitlab still hasn't managed to figure that out. Gitlab CI was also miles ahead of Github CI for a long time. Github is better now, but CI is one of the few things that really locks you into a vendor. Plus, Gitlab had much better enterprise pricing options for a long time. I'm not sure what it's like now. I don't have any numbers, but I suspect that Gitlab has more market share when it comes to locally hosted deployments.
