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/PSR-17 compatible HTTP and HTTP/2 server and can be used to replace classic Nginx+FPM setup with much greater performance and flexibility.
