Batavia is a Python virtual machine implemented in JavaScript, allowing Python 3.5+ bytecode to run in the browser. It is an early alpha project from the BeeWare project that is currently on hiatus.

Use cases

  • run python code in the browser
  • execute python bytecode in javascript
  • port python programs to the web
  • embed a python interpreter in a web page
  • interoperate python objects with javascript

When to choose

  • you need to run simple Python 3.5-era bytecode in a browser without a server
  • you want to study or experiment with a Python VM implemented in JavaScript

When to avoid

  • you need a maintained or production-ready Python-in-browser solution
  • you need modern Python (3.8+) features or recent standard library support
  • you want Python on the web today - WASM-based tools like Pyodide are better supported
