Worker mode

  • Worker script

    Boot your app once, it stays in memory!

  • Straightforward

    Natively supported by Symfony, API Platform, Laravel…

  • Simple

    Uses plain old superglobals: no need for PSR-7.

  • Fast

    According to our benchmarks, 3.5x faster than FPM on API Platform apps.

  • Efficient

    FrankenPHP is written in Go and C. It relies on Go’s iconic feature: goroutines!

  • Optional

    Your app can be served as-is, even if it isn’t compatible with the worker mode.

  • Easy Deploy

    Runs in process: one binary, no external service needed.

Fast as lightning

So easy to configure!

Five lines of config: it’s now all you need to start a production-grade PHP server (automatic HTTPS, HTTP/3, Brotli compression…), powered by Caddy.
    # Enable FrankenPHP
    order php_server before file_server

localhost {
    # Enable compression (optional)
    encode zstd br gzip
    # Execute PHP files in the current directory and serve assets
