Jupyter Notebook vs Polynote:
a side-by-side comparison for 2026

Jupyter Notebook (formerly IPython Notebook) is the classic web-based interactive computing environment for creating notebook documents. It provides a simple, streamlined interface focused on a single document workflow.

Polynote is a different kind of notebook. It supports mixing multiple languages in one notebook, and sharing data between them seamlessly. It encourages reproducible notebooks with its immutable data model.
