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
