Python Compiler in the Browser

A minimal, fast, zero-backend Python playground built with:

• CodeMirror 6 for the editor
• Pyodide to run Python directly in the browser
• Pure frontend — no server, no API, no containers

---

Features

• Syntax highlighting, autocompletion, bracket matching
• Works fully offline after first load
• Proper Python indentation behavior
• Extremely lightweight architecture
• No backend required

How It Works

The app combines three powerful pieces:

1) CodeMirror 6

Provides the code editor with Python language support and indentation rules.

2) Pyodide

Loads a full Python interpreter compiled to WebAssembly inside the browser.
