With apologies to the GitLab team, our views of how to make good software vary drastically and yours may be more in line with other peoples, but not mine: Maybe Gitlab's gotten better recently, but it's probably the most annoying piece of software I've ever used (well, second to Confluence maybe). It does everything which might be appealing to some, but for me it just meant everything was confusing, inconsistently labeled and documented, and/or buried under 5 levels of menus or under buttons that made no sense.

The way I explain it is you know how when your computer illiterate parents ask you to do some simple task that you have literally no idea how to do, but you look at some menus that have vaguely similar sounding titles based on your years of building up intuitions about how computer UIs work, click those menus, find what you need and do the task? GitLab breaks all those intuitions so easy tasks become hard.

YMMV, of course.

I've been using Sourceforge recently and am pretty happy with it overall, though it's still very alpha quality.
