About
marimo is a next-generation Python notebook is an open-source, Python-first reactive notebook that keeps code, outputs and program state in sync, adds built-in SQL and interactive widgets, and lets you run notebooks as scripts or share them as web apps; everything is stored as Git-friendly .py so notebooks are reproducible and production-ready. Its AI-native editor surfaces copilots, context-aware chat, inline edits and model integrations (hosted or local) for autocomplete, error fixing and code generation, making marimo a fast, more reliable alternative to Jupyter for data scientists, ML engineers, educators and teams who want reproducibility, faster iteration, and easy app deployment.
