Reactive Python notebooks that stay reproducible, git‑friendly, and deployable
marimo is a reactive Python notebook that automatically updates dependent cells, stores notebooks as pure .py files, supports UI interactivity, SQL, AI assistance, and can be run as scripts or web apps.
When teams consider marimo, these hosted platforms usually appear on the same shortlist.
Looking for a hosted option? These are the services engineering teams benchmark against before choosing open source.
Exploratory data analysis with live filters
Analysts adjust sliders and instantly see updated visualizations, keeping results consistent and reproducible.
Automated reporting pipeline
Run notebooks as scripts with CLI arguments to generate reproducible reports on a schedule.
Deploying an interactive dashboard
Convert a notebook to a web app that stakeholders can use without installing Python.
AI‑augmented notebook authoring
Generate data‑aware code snippets via the built‑in AI assistant, accelerating prototyping.
Use `pip install marimo` or `conda install -c conda-forge marimo`. For extra features, install with `marimo[recommended]`.
Yes, run `marimo convert your_notebook.ipynb > your_notebook.py` or use the web conversion interface.
When a cell runs, marimo statically analyzes variable references and automatically runs all dependent cells or marks them stale.
Notebooks are stored as plain `.py` files, making them fully compatible with Git and other VCS tools.
Use `marimo run your_notebook.py` to launch an interactive web app, or share via the molab cloud service.
