[Interactive Notebooks: Marimo](#/marimo?id=interactive-notebooks-marimo)
-------------------------------------------------------------------------

[Marimo](https://marimo.app/) is a new take on notebooks that solves some headaches of Jupyter. It runs cells reactively - when you change one cell, all dependent cells update automatically, just like a spreadsheet.

Marimo’s cells can’t be run out of order. This makes Marimo more reproducible and easier to debug, but requires a mental shift from the Jupyter/Colab way of working.

It also runs Python directly in the browser and is quite interactive. [Browse the gallery of examples](https://marimo.io/gallery). With a wide variety of interactive widgets, It’s growing popular as an alternative to Streamlit for building data science web apps.

Common Operations:

```

# Create new notebook

uvx marimo new



# Run notebook server

uvx marimo edit notebook.py



# Export to HTML

uvx marimo export notebook.pyCopy to clipboardErrorCopied

```

Best Practices:

1. **Cell Dependencies**

   * Keep cells focused and atomic
   * Use clear variable names
   * Document data flow between cells
2. **Interactive Elements**

   ```

   # Add interactive widgets

   slider = mo.ui.slider(1, 100)

   # Create dynamic Markdown

   mo.md(f"{slider} {"🟢" * slider.value}")Copy to clipboardErrorCopied

   ```
3. **Version Control**

   * Keep notebooks are Python files
   * Use Git to track changes
   * Publish on [marimo.app](https://marimo.app/) for collaboration
