Python Playground
Python Online Code Runner
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
