How this works

The first Run downloads Pyodide — CPython compiled to WebAssembly (~10 MB, cached afterward) — then executes your code in a sandbox inside the tab. Imports like numpy, scipy, and matplotlib are auto-installed on demand. Because it's all local, your code and data never leave your machine, and it costs us nothing to run — the same “free, browser-native” principle as every solver on PolySim.
