This is not able to compete with Github or BitBucket... I actively work on GitLab and there are a ton of issues and missing features that are highly important, and will most likely turn away users.
I see that you had your share of issues with Gitlab. I agree that it will need a lot of work before being as fully featured as Github or BitBucket. But I believe it can grow quickly because of the community around it, there is an obvious need for an open source solution. And I hope I can pleasantly surprise the 350+ people that signed up for the beta program in the last 5 hours.
Most of which won't be solved anytime soon.
But I wish you good luck.
