Working on Runno (https://runno.dev/) as a side project. It's a tool for running code in the browser for educational use.

[Edit]: I wrote a re-introduction to Runno: The WebComponent for Code over the weekend (https://runno.dev/articles/web-component/)

I've been playing around with turning it into a sandbox for running code in Python (https://runno.dev/articles/sandbox-python/). This would allow you to safely execute AI generated code.

Generally thinking about more ways to run code in sandbox environments, as I think this will become more important as we are generating a lot of "untrusted" code using Gen AI.
