RoadRunner is an open source (MIT licensed), high-performance PHP application server, load balancer and process manager. It supports running as a service with the ability to extend its functionality on a per-project basis.

RoadRunner includes PSR-7 compatible HTTP/HTTPS server and can be used to replace classic Nginx+FPM setup with much greater performance.
