marimo is doing a launch week

One week. Five announcements. Can you guess what's coming?

Python is better than PowerPoint now. You can present marimo notebooks as slides. Widgets stay interactive and you can edit slides live while presenting. No more second window, separate demo, or crossing your fingers.

182

marimo @marimo.io · 23/07/2026

marimo is reactive, which means that it knows in what order variables are declared. So what if you had widgets at your disposal that could leverage that? For launch week, we're releasing some tools that do exactly this.

141

marimo @marimo.io · 22/07/2026

Ask and you shall receive: marimo now runs natively in PyCharm. Open, edit, and run reactive notebooks in @JetBrains without leaving your IDE. Install from the JetBrains Marketplace 👇

Open any marimo notebook on GitHub. Click one button. The raw Python turns into a live, interactive notebook you can run, right there in your browser. That's marimo Glance. Free extension for Chrome and Firefox, works on GitHub, gists, and GitLab. Details below.

I finally tried out the @marimo.io marimo-pair skill to do some light data analysis and plotting in conversation with an LLM and it really worked. Tedious plotting layout and syntax fadeed into the background. I used OpenCode + GLM 5.2, @pola.rs and @matplotlib.org Would recommend. #EnergySky

A four-panel plot showing advanced metering deployment in Pennsylvania. The first panel shows how market penetration has changed over the years by customer class (residential, commercial, and industrial) with all classes approaching 100% penetration in recent years. The lower 3 panels show the percentage breakdown between standard (dumb) meters, one-way, and bidirectional advanced meters by customer class and year.

molab has free GPUs and we've been exploring the different ways that you could use them. And there's plenty to do outside of deep learning! You can use them to tackle TSP problems too. But it helps to rethink your CPU-based algorithms when you go here. youtu.be/1-5wkzdP1Jc

Now that molab has free GPUs we started toying with ideas that aren't 100% practical but might teach us something. So we asked a question: can we use deep learning to solve (NP)-hard computer science problems? Details are in the video below: youtu.be/QnP-EdJyiDo
