Features

FrankenPHP at a glance

Extensible

Compatible with PHP 8.2+, most PHP extensions and all Caddy modules.

Only one service

Designed with simplicity in mind: only one service, only one binary! FrankenPHP doesn’t need PHP-FPM, it uses its own SAPI specially handcrafted for Go web servers.

Easy deploy

Cloud Native app shipped as a Docker image. Compatible with Kubernetes, and all modern cloud platforms. It’s also possible to package your PHP app as a standalone, self-executable static binary.

Worker mode

Boot your application once and keep it in memory! It is ready to handle incoming requests in a few milliseconds.

103 Early Hints

Early Hints are a brand new feature of the web platform that can improve website load times by 30%. FrankenPHP is the only PHP SAPI with Early Hints support!
