Flarum is forum software written in PHP and mithril written by Toby Zerner, a med school student from Australia. Originally Flarum was created as a successor to esoTalk, a mockup of version two with the new name was entered in a design competition in 2013. A failed kickstarter did not become a setback as development continued.
Now, a few years later Flarum has three active core developers while using many components of the widely acclaimed Laravel framework. Although no stable version has yet been released, already adoption of the extensible forum software is gaining a lot of traction with over 1 million downloads of Flarum related packages, 370 extensions and many sites using it in production.
