Rymfony is a command-line tool to mimic the behavior of the Symfony CLI binary.


To install Rymfony, download your version from the latest release on the Releases page.

Download latest dev builds

The binary is built on every push to the main branch, if the binary can be built of course, and pushed to

This allows you to test the latest version right away!

Here are the links to download them:

All nightly releases

Unzip the file and put the rymfony executable file in your PATH, and you're set!

If you need more architectures and OSes, feel free to check the CI.yaml Github Action and contribute for more!

Download on Linux

curl -sSL -o && unzip && sudo mv rymfony /usr/bin/rymfony && sudo chmod a+x /usr/bin/rymfony && rm

Download on Windows

With cmd (powershell must be accessible):

powershell Invoke-WebRequest -OutFile && powershell Expand-Archive -Force . && rm

With Powershell directly:

Invoke-WebRequest -OutFile && Expand-Archive -Force . && rm

Then, add the rymfony.exe executable somewhere in your PATH.

Download on MacOS

curl -sSL -o && unzip && sudo mv rymfony /usr/local/bin/rymfony && sudo chmod a+x /usr/local/bin/rymfony && rm

Manual build

  • First, install Rust following the Official guide.
  • Clone the repository on your machine with this command:
    git clone
  • Then, run cargo build --release.
  • Done!
    The binary will be stored in ./target/release/rymfony (with .exe extension on Windows), you can use it directly!

$ rymfony
rymfony 0.1.0-dev
Alex Rock <>

A command-line tool to spawn a PHP server behind an HTTP FastCGI proxy,
inspired by Symfony CLI, but open-source.

    rymfony [FLAGS] [SUBCOMMAND]

    -h, --help       Prints help information
    -q, --quiet      Do not display any output. Has precedence over -v|--verbose
    -V, --version    Prints version information
    -v, --verbose    Set the verbosity level. -v for debug, -vv for trace, -vvv to trace executed modules

    help                   Prints this message or the help of the given subcommand(s)
    new:symfony            Create a new Symfony project
    php:list               List all available PHP executables.
    server:ca:install      Create and install a local Certificate Authority for serving HTTPS
    server:ca:uninstall    Uninstall the local Certificate Authority
    server:start           Runs an HTTP server
    stop                   Stops a potentially running HTTP server

Note: For any command, you can use the -h|--help flag to display its details too. If you are familiar with the Symfony console component it is very much similar.


rymfony serve (or server:start)

This command allows you to run a web server, in foreground or background, and you can customize the port to listen to.

$ rymfony serve --help
Runs an HTTP server

    rymfony server:start [FLAGS] [OPTIONS]

        --allow-http              Do not redirect HTTP request to HTTPS
    -d, --daemon                  Run the server in the background
    -s, --expose-server-header    Add server header into all response
    -h, --help                    Prints help information
        --no-tls                  Disable TLS. Use HTTP only.
    -V, --version                 Prints version information

        --document-root <document-root>    Project's document root
        --passthru <passthru>              The PHP script all requests will be passed to
        --port <port>                      The TCP port to listen to [default: 8000]

rymfony stop

If a server is running in the background running for the current project, it will be stopped.

Note that this is checked via a .pid file, containing the PID of the running server.

rymfony php:list

This will list all existing php binaries in your environment.

It will actually search in the PATH directories for any binary that matches some patterns like these:

  • On Windows:
    • php.exe
    • phpX.Y.exe
    • php-cgi.exe
    • phpX.Y-cgi.exe
    • php-cgiX.Y.exe
  • On other platforms:
    • php
    • phpX.Y
    • php-fpm
    • php-cgi
    • phpX.Y-fpm
    • phpX.Y-cgi
    • php-fpmX.Y
    • php-cgiX.Y

More locations for standard PHP installations that are searched can be found in

β„ΉNote: if your PHP binary is not detected, please open an issue so we can add support for it!

Here is the output from an Ubuntu 20.04 machine:

$ rymfony php:list

β„Ή Note: To search for PHP executables in a custom folder, you can define the RYMFONY_PATH environment variable.

On *nix systems, you must use the colon : path separator.
On Windows systeme use the semi-colon ; path separator.

# *nix
$ export RYMFONY_PATH=/home/php/php-dev:/var/local/php-dev

# Windows
> set RYMFONY_PATH=c:\php7.4;d:\php8.0;d:\php7.3


If you want to contribute to any of these points, feel free to do it!

  • 🟩 : Done
  • 🟨 : In progress (a PR should be linked)
  • πŸŸ₯ : Planned, but not started yet

To do (order of priority, done first):

  • Commands and command-line options
    • 🟩 Add a stop command.
    • πŸŸ₯ Create open:local command.
    • 🟩 Create server:logs command (needs #81 first).
    • πŸŸ₯ Create server:list command.
    • πŸŸ₯ Create server:status command.
    • πŸŸ₯ Create config command, to display project's config, and maybe change it.
    • πŸŸ₯ Create php command (should use the configured PHP version).
    • πŸŸ₯ Create console command for Symfony (should use the configured PHP version, and be compatible with SF 2+).
    • πŸŸ₯ Create artisan command for Laravel (should use the configured PHP version).
    • πŸŸ₯ Propagate global app arguments so they can be used in subcommands (like rymfony serve -v, because if you want verbosity today, you need to pass the option before the subcommand, like this: rymfony -v serve). Maybe this can be in the clap crate itself (the CLI app package used by Rymfony).
  • Releases
    • 🟩 Publish nightly builds of the binary as artifacts by using Github Actions.
    • 🟩 Add support for verbosity levels in output logging, like -v, -vv, -vvv and -q.
    • 🟩 Add version hash to nightly builds.
    • 🟩 Publish releases of the binary as artifacts by using Github Actions. For now, only "nightly" builds are released.
  • HTTP server
    • 🟩 Make sure we can run a web server using Hyper and Tokio.
    • 🟩 Put the web-server execution in a separate file.
    • 🟩 Execute the server in the background.
    • 🟩 Make sure the web server's IP and port can be customized through a --listen ip:port option.
    • 🟩 Once a "way to start PHP" is found (either via CGI on Windows, FPM on Linux, or PHP's native server for other cases), make sure we can start a background PHP process.
    • 🟩 Transform the standard web server into an HTTP proxy to PHP using a FastCGI client
    • 🟩 #81 Tail logs to a file when server is run in the background
    • πŸŸ₯ Make sure the server process is totally detached from the terminal in Windows. There are some issues about this, and it needs more investigation. Check this blog post section for more information.
    • πŸŸ₯ Make sure that Caddy server has the proper capabilities to run with port 80 at runtime instead of installation-time (to make sure the port can be used as a flag to whether this setcap feature must be used or not).
      Check the set_http_capabilities() function in the file for more details.
    • πŸŸ₯ When the server is stopped (via Ctrl+C or via a panic), make sure PHP is stopped too.
      • Note: on Windows, it seems that the ctrlc package does not work, something must be done on this!
    • πŸŸ₯ Allow listing running servers globally, without necessarily using a .pid file.
    • πŸŸ₯ Allow stopping a server globally, without necessarily using a .pid file.
    • 🟩 (note: handled by Caddy) Find a way to force the entire request-response workflow to be streamed instead of buffered (will make better performances and memory usage)
  • PHP server
    • 🟩 Create a tool to discover the php binary if none of the two above are detected.
    • 🟩 Create a tool to discover the php-fpm binary if on Linux.
    • 🟩 Create a tool to discover the php-cgi binary (I'm developing on Windows and it is therefore easier).
    • πŸŸ₯ Properly search for PHP binaries in the current machine
      • 🟩 When searching for PHP binaries, be able to flag their type (native, cgi, fpm) and their version.
      • 🟩 Implement a way to retrieve the current PHP version based on the "System" PHP script
      • πŸŸ₯ Search for PHP binaries elsewhere than in PATH, such as with Homebrew or phpenv. This will need many checks about the "standard locations" where PHP can be found.
        • 🟩 Search in /usr/bin for most Ubuntu defaults
        • 🟩 Search in /usr/local/Cellar for most Homebrew defaults on Mac
        • πŸŸ₯πŸ’‘ Please suggest more places where PHP could be present!
      • 🟩 Flag the current path-based php script to check its version and mark it as "System" (just like in Symfony CLI)
      • 🟩 Store a list of all PHP binaries in ~/.rymfony/php_versions.json
      • 🟩 Deserialize the php-versions.json config file if it exists when using binaries::all() or binaries::current() to make the command faster
      • 🟩 Add an option to the php:list command such as --refresh that will make another lookup and save the ~/.rymfony/php-versions.json file again πŸ˜„
      • 🟩 Implement a way to retrieve the current PHP version based on a local .php-version file
    • πŸŸ₯ Allow passing environment variables to PHP via an -e|--env option.
    • πŸŸ₯ Allow passing a custom option to specify which method the user wants to use to start PHP (like --use-fpm or --use-native, something like that).
    • πŸŸ₯ (utopia) Support setups that have multiple PHP versions installed (such as on Ubuntu/Debian with deb-sury's repo, or with Homebrew on OSX), and allow customizing the version.
    • PHP Server
      • 🟩 Don't rewrite the fpm-conf.ini configuration file each time a server is launched.
      • 🟩 Find a way to differenciate servers configurations, in case multiple servers are started: Done by creating a specific PHP-FPM configuration for each project πŸ™‚
  • Going way further
    • πŸŸ₯ (utopia) Detect whether the project uses Docker Compose
    • πŸŸ₯ (utopia) Be able to dynamically create environment variables for some common use-cases (database, redis, rabbitmq, mailcatcher).
