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

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! 🤖

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?

By app do you mean JupyterLab Desktop? If so, it unfortunately currently suffers from a lack of maintenance: github.com/jupyterlab/j... So hopefully there will be a solution for this because JupyterLab Desktop definitely helps address the "Getting Started" usability issue you mentioned.

Right, this has been indeed been discussed for a long time and keeps coming back: github.com/jupyterlab-c... One challenge is also to agree on what needs to be included by default. And if some of these extensions are not official, how to make sure they get proper support and maintenance.

Thanks 👍 Do you think it would already be an improvement if JupyterLab shipped with a couple of useful extensions like LSP or code formatting? For example in a different metapackage.

Jeremy Tuloup @jtp.io · 19/08/2025

Indeed! Although given the complexity dependency management, virtual environments, and all the different deployment scenarios, maybe a good starting point would be to explore this in an extension first.
