Phabricator is a free and open source [5] suite of web-based development collaboration tools.
Its suite of tools includes Differential, a code review tool, Diffusion, a repository browser, Herald, a change monitoring tool, [6] Maniphest, a bug tracker, and a wiki called Phriction. [5] It integrates with Git, Mercurial, and Subversion.
Phabricator was originally developed as an internal tool at Facebook [7] [8] [9] overseen by Evan Priestley. [1] Priestley left Facebook in 2011 to continue Phabricator's development in a new company called Phacility. [2]
Phacility announced that it was winding down operations and placing Phabricator in a bare minimum maintenance mode in 2021, [10] with no future updates expected.
A community fork, Phorge, was created and announced its stable release to the public on September 7, 2022, and is actively updated. [11]
