Phabricator/en

Phabricator is an open-source software development platform. In Wikimedia, Phabricator is used for project management, bug reporting and feature requests (see ), and in the future also for code review in an integrated fashion.

The migration to Phabricator is mostly complete. See the timeline page for more information.

Get started


If you have questions, check the Help page. Your questions are very welcome.

For a Wikimedia-centric overview, watch the Tech Talk The Very Basics of Phabricator. Former Bugzilla users are encouraged to read our Phabricator versus Bugzilla comparison.

You can also watch a screencast about handling tasks/bugs.

First missions include


 * Creating your account
 * Creating a task
 * If you maintain projects: Creating a project and learning about project management in Phabricator.


 * Etiquette


 * Learn to use Phabricator. Play and test in our Labs instance as much as you want. Check out the documentation and short videos on.

See the Wikimedia Phabricator bug workflow for more details.
 * Report bugs and features in the Phabricator software itself in the Phabricator project.

Weekly update / maintenance window
Phabricator doesn't have releases, and therefore it is up to us to decide how close do we want to follow the upstream version. There is a weekly window for updates and other maintenance tasks on Wednesdays at 5:00PM Pacific (Thursday Midnight, 0:00 UTC) (check your timezone) and users will get redirected to Phabricator/Maintenance. We don't necessarily update Phabricator every week, but we reserve this window to use as needed, usually twice per month, depending on the urgency of outstanding bugs fixed upstream. The expected downtime during this window is between 0 and 30 minutes.

Migration timeline
We are working on the migration of several developer infrastructure services to one single Phabricator instance. It's a very exciting project! We welcome your help.


 * Git and Gerrit users are welcome to the Gerrit-Migration project. We need help learning about the possibilities of Phabricator in this area: what is missing, what exists in a different way, what is remarkably interesting, which are the blockers that should be reported upstream?


 * As a PHP developer, you're welcome to contribute enhancements and new features upstream. Learn more at.
