JuputerLite also does this. Uses local storage and Pyodide kernel (python on wasm). It has a special version of pip, and wasm versions of a lot of libraries which usually use native code (numpy etc). Super impressive.

We are actually going on another direction.

Philosophically speaking I believe we should not require a special version of pip to install packages, nor a "lite" version of Jupyter to run in WebAssembly.

We should be able to run Jupyter fully within the Wasmer ecosystem without requiring any changes on the package (to run either in the browser or the server).
