#JupyterLite Officially Joins Project Jupyter!

🌟 JupyterLite, the lightweight, browser-based Jupyter distribution, has officially become part of Project Jupyter. This is a major milestone for accessible, no-installation-required data science and education.

With JupyterLite, you can run Jupyter notebooks directly in your browser - no server, and no setup. Whether you're teaching, prototyping, or collaborating, JupyterLite makes interactive computing more scalable and more accessible than ever, anywhere in the world, in Python, R, GNU Octave, and even C++.

This milestone is the result of years of hard work and innovation. A huge shoutout to the incredible team at QuantStack - Jérémy Tuloup, Martin Renou, Thorsten Beier, Isabel Paredes, Ian Thomas, Anutosh Bhat, and Johan Mabille - as well as community contributors Nick Bollweg and Agriya Khetarpal.

As part of Project Jupyter, JupyterLite will benefit from deeper collaboration, innovation, and growth. The future of interactive computing is brighter than ever! This journey wouldn’t have been possible without the support of QuantStack, Bloomberg, the Gates Foundation, and the Jupyter community.

A viewer for Parquet, SQLite, and Avro files in JupyterLab.
Check out our new JupyterLab extension: Arbalister. 🏹
Built upon Apache Datafusion, @ProjectJupyter, and Apache Arrow, it lazily fetches rows so that you can view files larger than memory!

🚀 The future of notebook sharing is here!

We are thrilled to introduce notebook.link, a platform that lets you create, share, and run Jupyter notebooks instantly in your browser, with no setup or installation required.

Powered by JupyterLite and WebAssembly, it supports Python, R, and C++, plus a full in-browser terminal experience.

Together with Nicolas Brichet at the @PyDataParis 2025 conference, we presented a vision for what AI in @ProjectJupyter can look like, with a focus on forward-looking, browser-based AI workflows.

Some of the topics we discussed:

- Agents in the browser
- Controlling JupyterLab with natural language
- AI-assisted 3D modeling
- Built-in Chrome AI and LLMs in the browser

The recording is now available on YouTube, happy watching!
