Installation

With Python

pip install parityrun

Python 3.10 or newer. pipx install parityrun or uv tool install parityrun install it as a command of its own, outside any project's environment.

Without Python

One line installs everything. On Windows (PowerShell):

powershell -ExecutionPolicy ByPass -c "irm https://raw.githubusercontent.com/arttujan/parityrun/main/install.ps1 | iex"

On macOS and Linux:

curl -LsSf https://raw.githubusercontent.com/arttujan/parityrun/main/install.sh | sh

The installer gets uv when it isn't there, and uv installs parityrun as a command of its own, with a Python of its own. If a terminal that was already open doesn't find parityrun, open a new one.

Checking and updating

parityrun --version

To update: pip install -U parityrun, or run the installer again (it installs the latest release), or uv tool upgrade parityrun.

What else is needed

parityrun starts your app and its ports as they start themselves, so it needs what they need:

For	Needed
a PHP app or library	php on PATH
line coverage of PHP code	the PCOV extension (or Xdebug); optional, see Getting Started
a Node.js app, or a JavaScript port	node
a TypeScript port	node 23.6 or newer (it runs TypeScript as it is)
a Rust app or port	cargo
a Python app	the app runs with the Python parityrun runs with: pip install parityrun into the app's own environment
parityrun port	Claude Code logged in, or your own AI tool's command line
MySQL, MariaDB or PostgreSQL	the database server, see Databases
