marimo

Marimo is an open-source, AI-native reactive Python notebook designed for data and AI workflows. It combines context-aware coding assistance, SQL-in-Python, interactive UI components, and deterministic, Git-friendly .py notebooks to deliver reproducibility, rapid iteration, and seamless app deployment. The platform is built to feel like a modern developer environment, with reactive execution that automatically updates dependent cells when code or values change, eliminating the need for manual state management. Marimo notebooks are stored as pure Python files, making them version-controllable with Git, reusable as modules, executable as scripts, and shareable as web apps via WebAssembly-powered HTML or the marimo CLI. The tool also includes first-class SQL support for querying dataframes and databases directly within notebooks, and integrates with AI assistants for code generation and debugging. Marimo is used by developers and data scientists for tasks ranging from exploratory data analysis and machine learning model training to building interactive dashboards and reproducible research. The platform is open source and available on GitHub, with additional cloud-based or enterprise features likely offered through a contact-based pricing model.
