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.

while ($req = $psr7->acceptRequest()) {
    try {
        $resp = new \Zend\Diactoros\Response();
        $resp->getBody()->write("hello world");

        $psr7->respond($resp);
    } catch (\Throwable $e) {
        $psr7->getWorker()->error((string)$e);
    }
