Running Python code in a sandbox with MicroPython and WASM

simonwillison.net·Jun 6, 2026

Simon Willison discusses his new alpha package, `micropython-wasm`, which allows for running Python code in a secure sandbox using MicroPython and WebAssembly. This approach aims to safely execute plugin-style code within applications, addressing concerns about security and resource management in traditional Python environments.

The key insight from Simon Willison's exploration of executing Python code in a sandbox using MicroPython and WebAssembly is the development of a potential solution for safely running plugin-style code with restricted privileges. The `micropython-wasm` alpha package offers a promising approach to sandboxing Python code, leveraging WebAssembly’s secure execution capabilities. This could be a valuable tool for enhancing the safety of plugin systems in Python applications, particularly for those concerned with limiting the risks of executing untrusted code. Consider experimenting with `micropython-wasm` for controlled code execution in your projects, especially if you're managing plugin systems.
