RoadRunner on Ubuntu 24.04

Overview

RoadRunner is a high performance PHP application server and process manager written in Go. Instead of restarting the PHP interpreter on every request, it starts a pool of long lived PHP workers once and keeps them warm, then dispatches each request to them over an efficient pipes relay. The result is far lower per request overhead than a traditional PHP FPM setup, with predictable memory use, graceful worker recycling and built in supervision. RoadRunner speaks PSR 7 and PSR 15 to your application, and its plugin architecture adds HTTP and HTTP/2 serving, gRPC, background jobs and queues and key value caching from a single static binary.

It suits teams running PHP frameworks and APIs that want lower latency and higher throughput than per request process managers can offer, on infrastructure they control.

Common uses

• Serve PHP frameworks and APIs with warm workers for lower latency and higher throughput
• Replace per request PHP FPM with a supervised, long lived worker pool you control
• Run PSR 7 applications, background jobs and gRPC services from one static binary
