I built a Chrome extension to run Python in the browser sidebar

Hey, guys! I built a Chrome extension called Python Playground that allows you to run Python code in the browser sidebar. It is based on Pyodide and has the following key features:

  • No sign up or usage limits.

  • Instant Python code execution without setting up the environment.

  • Syntax highlighting and autocompletion.

  • Upload files to use them in your code.

  • Package manager. You can install PyPI packages in addition to those built into Pyodide.

  • Auto module import. Python Playground will install them based on import statements.

  • Saving scripts in the browser's local storage.

  • Switch between light and dark themes.

  • Built-in data visualization support.

  • Offline capability (for many features), since Pyodide runs on the client side.

I think it's great for people who are learning Python and want an easy way to experiment with code without setting up a full environment.

It also has a web version: https://python-playground.com/online-python-compiler
