Marimo
A next-generation, reactive Python notebook designed to solve the hidden state problems of Jupyter by automatically re-running dependent cells.
What it is
Marimo fixes the biggest flaw in traditional notebooks: out-of-order execution. In Marimo, the notebook operates like a spreadsheet; if you change a variable in one cell, every other cell that depends on that variable updates automatically. It stores notebooks as pure, git-friendly Python scripts rather than messy JSON.
When you would use it
You use Marimo when you are frustrated by the unpredictable hidden states of Jupyter notebooks and want a modern, reactive environment that produces clean Python code.
Common operations
- Building interactive data dashboards with UI elements (sliders, buttons).
- Committing clean, reproducible data science scripts to version control.
