Marimo is a reactive notebook for Python. It allows you to rapidly experiment with data and models, code with confidence in your notebook's correctness, and productionize notebooks as pipelines or interactive web apps. Highlights.

reactive: run a cell, and marimo automatically updates all affected cells and outputs interactive: bind sliders, tables, plots, and more to Python — no callbacks required reproducible: no hidden state, deterministic execution order executable: execute as a Python script shareable: deploy as an app git-friendly: stored as .py files
