PyScript - Python in the Browser
summary
PyScript runs Python in the browser by bootstrapping Pyodide or MicroPython compiled to WASM and loading packages on demand. Demos include a Python-driven slideshow, a Folium map, a sampling profiler UI and a spreadsheet; performance pain points are specific: marshaling crosses cost ~50 ns each leading to batching fixes, and imports once show imports load ~626 modules causing a 15 s stall. A small UI toolkit (LTK 1700-line toolkit) and pragmatic JavaScript backends make the apps usable.
