Phabricator – GitHub Alternative written in PHP used by the Wikimedia Foundation
One thing to note if someone consider switching from GitHub to Phabricator: Phabricator use a pre-commit reviews based on patches rather than being branch-based like in GitHub&#x2F;GitLab&#x2F;BitBucket. Make sure to read the Phabricator Review Workflow[1] before making the switch, because everyone in your team have to change their workflow if they already used to Pull Request&#x2F;Merge Request workflow. :-)<p>That said, I always found Phabricator&#x27;s issue tracker (Maniphest) to be superior to GitHub Issues, with ability to create task dependencies (parent&#x2F;child) and ability to limit tasks permissions only to few selected groups (with spaces). It&#x27;s possible to setup Phabricator to mirror other repositories if you want to use only its issue tracker.<p>[1]: <a href="https:&#x2F;&#x2F;secure.phabricator.com&#x2F;phame&#x2F;post&#x2F;view&#x2F;766&#x2F;write_review_merge_publish_phabricator_review_workflow&#x2F;" rel="nofollow">https:&#x2F;&#x2F;secure.phabricator.com&#x2F;phame&#x2F;post&#x2F;view&#x2F;766&#x2F;write_rev...</a>
