GitLab B.V. Account manager here. I've noticed the links are broken, so here is the same comment as above, but with working links:

Take a look at the conversation that transpired on the blog post comments.

Here is a copy and past from the CEO for GitLab:

GitLab B.V. CEO here, as you might know GitLab is an open source project that is similar to GitHub and Bitbucket. Because it is open source some of our 700 contributors have contributed most of the top 5 feature requests you mentioned:

1. Contributor Statistics https://bitbucket.org/site/master/issue/4307/feature-request... => Available on https://gitlab.com/gitlab-org/gitlab-ce/graphs/master

2. Group repositories https://bitbucket.org/site/master/issue/2323/create-a-way-to... => GitLab has groups https://gitlab.com/gitlab-org/

3. Search source code https://bitbucket.org/site/master/issue/2874/ability-to-sear... => Available in the top bar of every project (uses git grep on the backend) https://gitlab.com/gitlab-org/gitlab-ce

4. Support for 2FA => Still not in GitLab, we would love to see it and we're accepting pull/merge requests for this http://feedback.gitlab.com/forums/176466-general/suggestions...

5. Separate permissions for wiki/issue tracker https://bitbucket.org/site/master/issue/2462/allow-admins-to... => In GitLab a guest can access the issue tracker but not the source code https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/perm..., this is not the case for the wiki.

You can use GitLab for free on GitLab.com with unlimited (private) repositories and collaborators. Currently we're at 5TB of repo's but it is growing fast. Feel free to reply to this comment if you have any questions.
