It’s that time of year again 🐍

Checkout the list of 100+ #jupyter #ai extensions I collated at github.com/openteams-ai...

xtralab has been my daily driver for software development for the past few months. It’s JupyterLab with opinionated defaults and pre-installed extensions for working with coding agents. I use it with Claude Code, Codex, and Pi most of the time. jtpio.github.io/xtralab

Contributing to open source also sometimes means playing the game of “who’s going to get that random CI failure and have to fix it?” 🥲

Recently I have been working on an opinionated JupyterLab metapackage for coding agents, called xtralab. It's basically JupyterLab with a set of extra extensions and curated defaults. If folks are interested, I may do a more in-depth video walkthrough soon! ➡️ Repo: github.com/jtpio/xtralab

Updated the passagemath-jupyterlite demo site. Now using JupyterLite 0.8 and providing several more passagemath distributions now available on emscripten-forge. passagemath.org/passagemath-... #Python #SageMath #OpenSource #Mathematics

JupyterLite 0.8 is released! 🎉 This release updates to the latest JupyterLab 4.6 and Notebook 7.6, and brings new improvements across related projects. ➡️ Try it online: jupyter.org/try-jupyter ➡️ Blog post: blog.jupyter.org/jupyterlite-...

JupyterLab 4.6 beta is now available for testing 🎉. It includes: - new layout customization options - navigation between recently edited cells - revamped keyboard shortcuts UI - editable breadcrumbs in file browser - debugger improvements Full changelog: jupyterlab.readthedocs.io/en/latest/ge...

The upcoming JupyterLab 4.6 release will let users customize the position of the activity bar in the left and right sidebars. Just another way to tweak the interface to your liking! 🛠️

Working on a new feature for the next JupyterLab 4.6 release that makes it easier to move panels and tabs across the interface and customize the layout to your liking. This is going to be useful for working with your favorite coding agent CLI right from within JupyterLab! 🤖

any-llm in action across three tools: • JupyterLite AI: connect once, access multiple providers • LangChain: swap models with a string • Headroom: optimize context and keep provider choice Each one shows a different part of the same idea. Full breakdown: link.mozilla.ai/any-llm-inte...

Hot off the press: a new JupyterLab extension that brings advanced, interactive visualizations to your JSON, YAML, and CSV files, powered by the jsoncrack library. ➡️ Repo: github.com/jtpio/jupyte... 💡 Try it in the browser: jtpio.github.io/jupyterlab-j...

One of the most common pieces of feedback from JupyterLite users is that it isn’t clear whether a file is server-provided or stored in the browser. Currently exploring ways to fix this with an improved UX. What do people think?

Recreating Ed Hawkins' climate spiral visualization in a Jupyter Notebook on notebook.link 🎨 The notebook uses NASA GISTEMP v4 monthly temperature anomalies from 1980 to 2025, and the p5.js JupyterLite kernel for ad-hoc visualizations 💡 ➡️ Try it in your browser: notebook.link/@jtp/paintin...

any-llm just got better. JupyterLiteAI connects through our OpenAI-compatible gateway. LangChain users install one package and switch models with a string. Headroom adds any-llm as a backend for context optimization. Read more: [https://link.mozilla.ai/any-llm-integrations

🎉 JupyterLite is now part of Project Jupyter! Run Jupyter notebooks directly in your browser: no server, no setup. Many thanks to the JupyterLite contributors and supporters like QuantStack, Bloomberg and the Gates Foundation. 🔗 blog.jupyter.org/jupyterlite-...

Everybody is talking about secure Python sandboxes for LLM code execution, but what about using the browser sandbox? Quick demo using JupyterLite and the Pyodide kernel 💡

Vibe coded a Jupyter Widget to show a minimal globe with some options in Jupyter Notebooks. Based on the cobe JavaScript library. ➡️ Install: pip install ipycobe ➡️ Try online: jtpio.github.io/ipycobe/note... Useful to quickly show data on a globe! 🌐

Together with @nicolasbrichet.bsky.social at @pydataparis.bsky.social 2025, we presented a vision for what AI @jupyter.org can look like, with a focus on forward-looking, browser-based AI workflows 🤖 The recording is now available on YouTube, happy watching! www.youtube.com/watch?v=cKeu...

JupyterLite now supports any-llm-gateway as a backend for its AI static front-end. any-llm-gateway routes LLM requests through a single gateway rather than tying usage to one provider. Integration details: link.mozilla.ai/jupyterlite-...

Current status: fixing 7 year old issues

👋 JupyterLab and Jupyter Notebook users: What's one thing you'd love to see improved in JupyterLab, Jupyter Notebook, or JupyterLite? The team is prepping the upcoming 4.5/7.5 releases and wants to tackle some usability issues. Drop your feedback below, this will help prioritize what gets fixed!👇

JupyterLite 0.7 alpha releases are now available, with already some nice new features 🎁 - Audio and video playback - Support for JupyterLab workspaces - Basic cell interrupt Try it in your browser and don't hesitate to share feedback, thanks! jupyterlite.rtfd.io/en/latest

Check out my talk from April at Université Grenoble Alpes, where I demoed the latest AI advancements in @jupyter.org. From %ai magics to generating notebooks and connecting to model providers, plus a peek at local browser models with JupyterLite 💡 www.youtube.com/watch?v=LiQl...

I just tried it. The fact that "input" now works is a major, major game changer. I just tried a few other things, and they all work perfectly -- certainly perfectly enough for my "Python for non-programmers" class. Wow. Kudos to the entire Jupyter team. I'm so impressed and delighted.

🎉 JupyterLite 0.6 is now available, and brings exciting new features: ✨ Interactive input() support 🔄 New REPL options 🎯 Better kernel status and logs ⚡️ Improved multi-tab experience Read more: blog.jupyter.org/jupyterlite-... Walkthrough video: www.youtube.com/watch?v=jkQ9...

just watched a very great overview of the latest updates in Jupyterlab and Jupyterlite - Improved code consoles, RTC, - Support for R via xeus-R; consoles - Improvements with xeus-python with some pip magic - JupyterAI and Jupyterlite-AI, with options for in-browser LLMs - hybrid kernels 🤯 (cont ⬇️)

Shared some Jupyter Frontends demos last week at Jupyter Open Studio Day (hosted by Bloomberg)! Covered: ✨ JupyterLab 4.4, Notebook 7.4 🧪 JupyterLite 0.6 🌐 In-browser Python/R 🖥️ Terminal w/ Vim 🧠 AI (WebLLM, on-device) ⚡ Hybrid kernels Thanks Bloomberg & all who joined! youtu.be/7kS_xfKEOmM

JupyterLab 4.4 and Notebook 7.4 are now available! 🎉 Coming with new features 🎁 - Code console improvements - Settings import and export - Workspace indicator - Kernel subshells support But also with bug fixes and other enhancements. Check out the blog post! blog.jupyter.org/jupyterlab-4...

Coming soon in the next JupyterLite release: ℹ️ Improved kernel loading indicator Sometimes it can be difficult to know if there is an issue when starting a kernel, or if the kernel has finished loading. So we're working on making it easier to check the kernel state and access the logs.

Cooking something 👀 💡

JupyterLab 4.4.0b1 and Notebook 7.4.0b1 are available for testing 🎉 - improved code console - settings import/export - better real time collaboration - workspace indicator - kernel subshells Please test: pip install --pre 'jupyterlab>=4.4.0b1' or pip install --pre 'notebook>=7.4.0b1'

R in JupyterLite 💡 😍 🎉
