How to use this tool

  1. Click “Load Python runtime” (first time).
  2. Paste Python code.
  3. Click Run and view stdout.

How to Use

Load the runtime once, then run Python snippets and inspect output and basic globals.

How It Works

Pyodide loads a WebAssembly-based Python runtime in the browser and executes your code locally.

Key Features

  • Client-side Python
  • Stdout output
  • Globals snapshot (best effort)

Secure & Private

No server execution. Code runs in your browser. Loading the runtime requires a network request to a public CDN.

Frequently Asked Questions

Is Python executed on a server?
No. Execution happens in your browser through Pyodide (WASM).
Does it work offline?
After the runtime is loaded and cached it may work offline, but initial load requires internet.
