A next-generation Python notebook: explore data, build tools, deploy apps!

marimo is a next-generation Python notebook where every notebook is also shareable as an interactive web app. It provides a seamless environment for exploring data, running experiments, building tools, and deploying apps.


  • Reactive: When you run a cell, marimo automatically runs all other cells that depend on it, similar to a spreadsheet. This reactivity, combined with built-in interactive UI elements, allows you to create powerful notebooks and apps that make your data tangible.
  • Interactive: Connect inputs like sliders, dropdowns, plots, and more to Python, enabling interactivity in your notebooks.
  • Expressive: Write dynamic markdown parametrized by UI elements, plots, or anything else, making your notebooks more flexible and expressive.
  • Pythonic: marimo uses pure Python without callbacks or magical syntax, providing a familiar programming experience.
  • Git-friendly: Notebooks are stored as .py files, making them friendly for version control using Git.


  1. Install marimo by running pip install marimo in a terminal.
  2. To see a tutorial notebook in your browser, run marimo tutorial intro.
