Marimo: Reimagining Jupyter Notebooks as Versionable Pure Python

Marimo is an open-source project that reimagines Jupyter Notebooks as pure plaintext Python files, usable as regular Python programs. Traditional Jupyter Notebooks' JSON-based .ipynb format leads to version control headaches, poor code reusability, and other issues. Marimo solves these by representing notebooks as dataflow graphs, making them easily versionable (with Git), importable as modules, testable with pytest, and executable as scripts. It also supports embedding SQL and Markdown and offers caching for efficiency. Marimo has seen wide adoption, used by companies like OpenAI and BlackRock, and numerous research institutions, quickly establishing itself as a new standard for interactive computing.
