JupyterLite

JupyterLite is a JupyterLab distribution that runs entirely in the browser built from the ground-up using JupyterLab components and extensions.

✨ Try it in your browser ✨

JupyterLite works with both JupyterLab and RetroLab.

Features

For more details, see the JupyterLite documentation.

Browser-based Interactive Computing

Python kernel backed by Pyodide running in a Web Worker
JavaScript kernel running in an IFrame
Combine Offline Notebook storage in browser localStorage or IndexDB with example files
Support for saving settings for JupyterLab/Lite core and federated extensions
Basic session and kernel management to have multiple kernels running at the same time
Support for Code Consoles
Initial support for visualization libraries such as matplotlib and altair

Ease of Deployment

Served via well-cacheable, static HTTP(S), works on most static web hosts, and locally
Embeddable within larger applications
Requires no dedicated application server much less a container orchestrator
Fine-grained configurability of page settings, including reuse of federated extensions

Status

⚠️ Currently in active development ⚠️

Development install

See the contributing guide for a development installation.

JupyterLite is a reboot of several attempts at making a full static Jupyter distribution that runs in the browser, without having to start the Python Jupyter Server on the host machine.

The goal is to provide a lightweight computing environment accessible in a matter of seconds with a single click, in a web browser and without having to install anything.

This project is a collection of packages that can be remixed together in variety of ways to create new applications and distributions. Most of the packages in this repo focus on providing server-like components that run in the browser (to manage kernels, files and settings), so existing JupyterLab extensions and plugins can be reused out of the box.
