Marimo is the new generation of Python notebooks: reactive, reproducible, and reusable. When you run a cell or interact with a UI element, all dependent cells automatically rerun (or are marked as stale), ensuring perfect consistency between code and results.

Key feature: notebooks are stored in pure Python, with first-class SQL support. They are therefore version-controlled with Git, executable as scripts, and deployable as interactive web apps or slides — even in the browser via WASM. Marimo replaces Jupyter, Streamlit, jupytext, ipywidgets, and papermill, linking sliders, tables, and charts to Python without callbacks.

Designed for data analysis and collaborative use cases, Marimo integrates SQL to query dataframes, databases, warehouses, or lakehouses, and fits into a modern, productive editor. Deployed in a Docker container on sovereign infrastructure, it keeps all your data and analyses safe on your instance.
