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
