Snakes in a browser
summary
Explains how Python validation and UI logic move into the browser by shipping bytecode not source and running it on a small JS VM, avoiding heavy interpreters. Compares Brython (~500 KB) and Pypy.js (~10–15 MB) with a lightweight bavia (≈10 KB) that runs CPython bytecode, notes it's slower but responsive enough for validation, and shows a deployed Django site plus a client UI with user-space client ~30–40 lines of Python.
