For years I've used PHP-CS-Fixer on both personal and commercial projects. I like its ruleset, but I also like how fast Mago is.
So when I started working on a PHP compiler, I decided to build a formatter that follows PHP-CS-Fixer's rules and runs at a speed comparable to Mago's. It's written in PHP and compiled with the Manticore compiler, so there's no PHP runtime to install.
It's early (v0.1.x), so it may be unstable. Bug reports with a small snippet are very welcome.
