## What it is
Polynote is a polyglot notebook environment supporting Scala, Python (with or without Spark), SQL, and Vega in a single notebook with seamless cross-language sharing. It offers IDE-quality code editing, a WYSIWYG text editor with TeX support, and runtime insight via task views and a symbol table.

## Use cases
- run Scala and Python in the same notebook sharing variables
- use Spark from a notebook with better editing than Zeppelin
- get autocomplete and compile error highlighting in notebook cells
- track defined variables with a symbol table while prototyping
- write rich text and TeX equations alongside code cells
- visualize data with Vega from a notebook

## When to choose
- you work primarily in Scala or mix Scala and Python in data work
- you want IDE-like editing features in a notebook
- you use Spark and find Jupyter/Zeppelin lacking

## When to avoid
- you need the vast Jupyter kernel and extension ecosystem
- you only use Python and are happy with Jupyter
- you need a fully mature, widely supported production tool

## Facets
- artifact type: application
- maturity: active
- function: data-science, data-visualization, interpreter, developer-tools
- domain: data-science, developer-tools, data-visualization
- platform: cross-platform, jvm, python, self-hosted
- tags: notebook, scala, spark, polyglot, jupyter-alternative, ide-like-editing, web-server
