JupyterLite: run all your code in a web browser using WebAssembly
summary
JupyterLite runs entirely in the web browser using WebAssembly, demonstrating CPython via pyodide and xeus-python kernels, compiled C++ notebooks (a ray tracer) and a browser terminal with git and vim that all actually execute in demos. Deployment builds produce a static site that scales to millions with only static files and can be hosted on GitHub Pages; notebook.link adds cloud storage and caching. Limitations include single-thread/multiprocess constraints, poor handling of very large datasets, and fixed kernel Python versions.
