Phabricator[0] is a more mature alternative if anyone is interested in an open source and free substitute for GitHub. I think the only thing GitLab might have over Phabricator is a familiar GitHub like UI. Phabricator was an internal Facebook project that was open sourced. It&#x27;s actually far more than just a substitute for GitHub. It has a much better system for managing issues, and better code review tools as well as other powerful features. My favorite feature is the herald system[1].<p>[0] <a href="http:&#x2F;&#x2F;phabricator.org&#x2F;" rel="nofollow">http:&#x2F;&#x2F;phabricator.org&#x2F;</a><p>[1] <a href="https:&#x2F;&#x2F;secure.phabricator.com&#x2F;book&#x2F;phabricator&#x2F;article&#x2F;herald&#x2F;" rel="nofollow">https:&#x2F;&#x2F;secure.phabricator.com&#x2F;book&#x2F;phabricator&#x2F;article&#x2F;hera...</a>
