Datalore vs Polynote

Datalore is a collaborative data science platform for exploring, analyzing, visualizing and sharing data. Its Jupyter-compatible notebooks provide coding assistance for Python, Kotlin, Scala and R, with native SQL cells that can transfer query results into pandas DataFrames. Teams can edit code together in real time and share notebooks with view or edit access. Notebooks can become data stories or static and interactive reports. Datalore AI can help write Python, SQL and R code, describe findings and fix errors. Database connections include Amazon Redshift, Azure SQL Database, MariaDB, MySQL, Oracle, PostgreSQL and Snowflake; AWS S3 and Google Cloud Storage buckets can be mounted as notebook folders. The free plan includes 120 CPU S machine hours and 10 GB of cloud storage. The Cloud plan costs $35 a month, billed monthly. On-Premises deployment runs on 64-bit Linux using Docker Compose or Kubernetes, but not on ARM, macOS or Windows hosts. JetBrains states that Datalore deployments are SOC 2 Type II certified and GDPR compliant.

Polynote is free, open-source notebook software with first-class Scala support. One notebook can mix Scala, Python, SQL, and Vega while sharing data between languages. Its immutable data model and ordered cell semantics support reproducible work. Editing includes autocomplete, error highlighting, rich text, and LaTeX equations. The interface tracks kernel tasks and highlights the statement currently running. A plot editor and Vega support handle visualization. Polynote integrates with Apache Spark for Scala and Python; Python runs through Jep in the JVM and can share data with Scala. The software is a JVM-based server that serves a web client and is distributed for self-hosting on Linux, macOS, and other listed environments. It supports Jupyter .ipynb and Zeppelin .json formats. Runtime documentation reports successful testing with Java 8 and Java 11 and requires Python 3 with pip. Installation warns that arbitrary remote code execution makes internet-accessible deployment unsafe.
