Polynote

First-class Scala support means the API and documentation are heavily oriented towards Scala patterns, which can be challenging for users primarily familiar with other languages like Python or R.

Compared to more established platforms like Jupyter, Polynote has a smaller ecosystem of plugins and extensions, which can limit its functionality for certain workflows.

Interactive data exploration and visualization can become sluggish or unresponsive when working with very large datasets, impacting productivity during analysis.

While basic usage is covered, detailed guides on how to implement complex functionalities are sparse, requiring users to dive into the source code or community forums for solutions.
