marimo Reactive Python Notebook

marimo is an open-source reactive Python notebook library that enhances traditional notebooks by guaranteeing consistency between code and outputs. It stores notebooks as pure Python files, making them Git-friendly, executable as standalone scripts, and deployable as interactive web applications. marimo also provides built-in UI elements and first-class SQL support. The current version is 0.23.1, and the project has an active development and release cadence.
