JupyterLite Xeus

jupyterlite-xeus is an extension for JupyterLite that enables fully client-side Jupyter environments powered by xeus kernels compiled to WebAssembly (Wasm). It allows users to create statically-served Jupyter deployments with custom pre-built environments — no server required.

The core feature of jupyterlite-xeus is its integration with emscripten-forge, a conda package distribution tailored for WebAssembly. This makes it possible to bundle your favorite scientific or data analysis packages directly into the browser-based environment, delivering a reproducible computing experience with zero backend dependencies.

Ideal for demos, educational resources, and offline computing. Use it in combination with Voici!

Currently supported kernels are:

Requirements
