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?” 🥲

Jeremy Tuloup @jtp.io · 05/08/2026

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

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?

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: [link.mozilla.ai/any-llm-integrations

The option to change console prompt position is available under the three dots button in the console toolbar, which is the last toolbar button

Toggling all the three new settings transforms the console into a single cell

The Import and Export buttons in the Settings Editor are the first two items in the toolbar panel
