The JupyterLab extension ecosystem just crossed 700 extensions compatible with JupyterLab 4. Here's what the latest wave tells us about where notebooks are heading.

Skills Hub: Building an Enterprise Trust Layer for AI Agent Skills

How our team won Judges' Recognition at Anaconda's CKO 2026 hackathon in Portugal by building an enterprise trust layer for AI agent skills.

Jupyter Projspec: Bringing Project Discovery to JupyterLab

A JupyterLab extension that automatically discovers and displays project structure — built in collaboration with Martin Durant and Rosio Reyes at Anaconda

Text-to-speech for Claude Code that automatically lowers your music when it speaks - like Google Maps in CarPlay.

PyData Boston 2025 lightning talk on non-code contributions to Open Source

I had an opportunity to present at PyData Boston 2025 about analyzing the JupyterLab extension ecosystem.

The talk analyzes the current state of the JupyterLab extension landscape in 2025 using public PyPI (via BigQuery) and GitHub data to quantify growth, momentum, and health by examining metrics such as monthly downloads by category, release recency, the relationship between stars and downloads, and the emergence of AI-focused extensions.

The fun did not stop after JupyterCon. Next Monday after the conference, Bloomberg invited everyone to their office to collaborate on Jupyter projects. There were many of the friendly faces who decided to make a trek from Southern California to the Bay while there were here for JupyterCon.

Another JupyterCon is in the books!

I have been a part of this community for the last 7 years, starting as a user, then building on top of Jupyter OSS projects and API and finally starting to contribute back to the core projects. I am really grateful for all the people I met along the way 🙏 This post is a reflection on my experience.

Learn how Mito's execution-based evaluation approach focuses on the functional results of AI-generated code rather than superficial similarity.
