Phabricator (pronounced like the word fabricator) is a suite of web applications which make it easier to build software, particularly when working with teams. Phabricator is largely based on Facebook’s internal tools.
It has been more than three years since I have been using Phabricator (self-hosted) at work. It is one of the open-source projects which has inspired me a lot. I have seen it grow over these years; every day it gets better. Thanks to hundreds of open-source developers for their contribution.
Want to see how to develop elegant and sophisticated software, even with a poor programming languages like PHP? Look at Phabricator’s source-code and tools (built using PHP), you would be awestruck.
Want to play with Phabricator without installing? Have a look at PhorePlay (Phabricator hosting service), which offers free Phabricator hosting (with multiple instances) up to five users. I think, that’s good enough for most of us (small teams).
Phabricator’s core team is working to launch Phacility (Phabricator Hosting). I think, it has potential to become something like Github (useful and essential service) one day.
