I've had lots of fun with WASM Python in the browser - a few of my experiments with that are: - https://lite.datasette.io https://lite.datasette.io - my Datasette app in a browser - https://simonw.github.io/research/pyodide-asgi-browser/datasette.html https://simonw.github.io/research/pyodide-asgi-browser/datas... is a new, improved version of that using Service Workers that's still a little experimental - notes here: https://simonwillison.net/2026/May/30/pyodide-asgi-browser/ https://simonwillison.net/2026/May/30/pyodide-asgi-browser/ - https://tools.simonwillison.net/micropython https://tools.simonwillison.net/micropython runs a MicroPython playground in the browser via WebAssembly My use-cases for server-side WASM Python are described here: https://simonwillison.net/2026/Jun/6/micropython-in-a-sandbox/#why-do-i-want-a-sandbox- https://simonwillison.net/2026/Jun/6/micropython-in-a-sandbo... - basically I want to offer end-user customization features that run custom code without buggy or malicious code crashing my app or leaking their data.
