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

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?

JupyterCon is almost there! I will be presenting one of the possible views for what AI in Project Jupyter can look like, with a focus on forward-looking browser-based AI workflows. If you haven't registered yet and feel like attending, there is still time to do so. See you all in San Diego, CA 👋

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.

What if we could use AI models like Llama 3.2 or Mistral 7B in the browser with JupyterLite? 🤯 Still at a very early stage of course, but making some good progress! Thanks to WebLLM, which brings hardware accelerated language model inference onto web browsers, via WebGPU 🚀

Currently working on improving the JupyterLab code consoles, to be able to change the position of the prompt cell and not clear code on execute. This would allow for more use cases such as a "Single Cell" usage, while leveraging all the features the console already provides ✨
