THE FUTURE OF PYTHON NOTEBOOKS

marimo is an open-source reactive notebook for Python — reproducible,
git-friendly, executable as a script, and shareable as an app.

THE NOTEBOOK YOU'VE ALWAYS WANTED

marimo notebooks are reproducible, extremely interactive, designed for
collaboration (git-friendly!), deployable as scripts or apps, and fit for the
modern Pythonista.


OUTPUTS UPDATE AUTOMATICALLY

Run one cell and marimo reacts by automatically running affected cells,
eliminating the error-prone chore of managing notebook state.

marimo's reactive UI elements, like dataframe GUIs and plots, make working with
data feel refreshingly fast, futuristic, and intuitive.

Rapidly experiment with code and models

Bind UI elements to Python values

Pick-up-and-play design, with depth for power users




PYTHON-FIRST DESIGN

marimo notebooks are pure Python and stored as .py files

Version with git, run as Python scripts, import symbols from a notebook into
other notebooks or Python files, and lint or format with your favorite tools.





REPRODUCIBLE BY DEFAULT

Code with confidence in your notebook's correctness.

You'll always be able to reproduce your collaborators' results. Notebooks are
executed in a deterministic order, with no hidden state — delete a cell and
marimo deletes its variables while updating affected cells.





BUILT FOR COLLABORATION

Collaborate on notebooks with git: small changes yield small diffs. Goodbye
JSON, hello Python!

Want to share outputs? Export to static HTML, or serve your notebook as a web
app with the marimo CLI.

MADE FOR DEVELOPERS

We care a lot about developer experience.

The marimo editor comes with GitHub Copilot, autocomplete, hover tooltips, vim
keybindings, code formatting, debugging panels, and extensive hotkeys. marimo
also ships with a CLI, a library, and a VS Code extension. Learn more at our
docs.




GO FROM PROTOTYPE TO PRODUCTION

marimo makes it seamless to go from prototype to production.

Run as Python scripts, locally or in pipelines

Deploy as read-only web apps


MADE WITH MARIMO

marimo lets you make just about anything. Here are example notebooks to jog your
imagination.
