About Python Playground

Hi everyone,
I'm working on Python Playground - a browser-based Python environment powered by Pyodide.

What is Python Playground?

Python Playground is a fast, lightweight way to run real Python directly in the browser using CPython compiled to WebAssembly.
All execution happens fully client-side, with no servers involved and no installation required.

You can try it here:
Website: https://python-playground.com/
Chrome Extension: https://chromewebstore.google.com/detail/python-playground/jfippgilnpggpddhmfjaaecadnfhcopa

Key features

• Real CPython runtime in the browser (Pyodide)

• Support for NumPy, Pandas, Matplotlib, Seaborn, SciPy, Plotly, and other pure-Python packages via package manager

• Inline data visualizations rendered directly in the UI

• File upload and a sandboxed virtual filesystem

• Code execution runs inside a Web Worker, so the UI stays responsive

• Works both as a web app and a Chrome Extension

• Perfect for teaching, experimenting, testing snippets, data exploration, and quick scripts

Use cases

• Trying out Python library snippets

• Teaching Python basics without installation

• Quick data analysis and plotting

• Running small scripts or algorithms

• Prototyping ideas in seconds
