## What it is
JupyterLite is a JupyterLab distribution that runs entirely in the browser, built from JupyterLab components and WebAssembly-powered Python kernels like Pyodide. It can be deployed as a static website, letting users run notebooks with no server or installation.

## Use cases
- run jupyter notebooks in the browser without a server
- host a static interactive python playground on github pages
- embed python coding exercises in documentation or a course site
- try pandas and matplotlib without installing python
- build a zero-install data science demo for students
- deploy jupyterlab as a client-side web app

## When to choose
- you want notebooks accessible with zero installation or server backend
- you need to embed interactive Python demos in docs, tutorials, or static sites
- your workloads fit in the browser (Pyodide-compatible packages, small data)
- you want offline-capable or CDN-hosted computing environments

## When to avoid
- you need heavy packages, GPUs, or large datasets beyond browser memory limits
- you rely on a real Python environment, native extensions, or shell access
- you need multi-user server features, real-time collaboration, or full JupyterHub parity
