marimo

A reactive Python notebook that's reproducible, git-friendly, and deployable as scripts or apps.

marimo is a reactive Python notebook: run a cell or interact with a UI element, and marimo automatically runs dependent cells (or marks them as stale), keeping code and outputs consistent. marimo notebooks are stored as pure Python, executable as scripts, and deployable as apps.

Highlights.

reactive: run a cell, and marimo automatically runs all dependent cells
interactive: bind sliders, tables, plots, and more to Python — no callbacks required
reproducible: no hidden state, deterministic execution
executable: execute as a Python script, parametrized by CLI args
shareable: deploy as an interactive web app, or run in the browser via WASM
data-centric: built-in SQL support and data sources panel
git-friendly: stored as .py files
