Run Concurrently

A pure python, zero dependency, package to run a list of commands concurrently.

Installation

Install from PyPI:

pip install run-concurrently

or, if you prefer to keep it isolated:

pipx install run-concurrently

Features

• Zero dependencies – works with the Python standard library only
• Colour‑coded output – each command gets its own colour so logs are easy to follow
• Graceful shutdown – sends SIGINT/SIGTERM to all child processes on exit
• Cross‑platform – tested on Linux, macOS, and Windows

Usage

Run any number of commands concurrently:

run-concurrently \
  "tail -f app.log" \
  "uvicorn app:app --reload"

By default, run-concurrently stops all commands as soon as one of them exits with a non‑zero status.
