JupyterLite: a JupyterLab distribution that runs in the browser
JupyterLite is such an incredible piece of software. It came out of the Pyodide project, which first got Python compiled to WebAssembly working in the browser.<p>It really is astonishing that they've managed to get the full data science Python stack - a lot of it based around custom C extensions (numpy, Pandas etc) running entirely in the browser.
