marimo

I’ve been using Marimo for over a year and it is the best damn notebook environment I’ve ever used. When I was learning ML, half my time was spent debugging variables that were out of sync with my cells, figuring out the commands to plot things correctly, and other annoying tedium. No more. I make stuff in Marimo and the slider elements and dynamically updating cells are soooooo cool. I didn’t realize notebooks could be fun! This is so obviously the future of data science. Looking forward to see what else Marimo team builds going forward.

We are using marimo in production at Owkin (AI biotech), to build data visualization apps. To me it is really the fastest tool to build simple apps, 1 order of magnitude faster than concurrents like streamlit. We do simple prototypes, and then iteratively grow them into production grade apps. Secondly, the intuitive notebook-based approach + the interop with rich python ecosystem, enables our data scientists, computational biologists, and more, to contribute to app building. Last, since it is all defined as code (git friendly), we can easily manage contributions from all stakeholders: data preparation code, plots, components, apps. It's awesome !

This is the best Python notebook! I'm a power user of notebooks and none of them come close to the reactivity and interactivity marimo offers. I also really like that the file format is pure Python. I can't wait to see what's next.
