Hex vs Polynote

Hex is a hosted data platform for exploring data, asking questions, and building data applications through notebooks and conversational self-service. It supports SQL, Python, and R, with real-time collaboration and version history. Users can connect data warehouses and local TXT, CSV, JSON, Parquet, Avro, and XLSX files, as well as metadata, semantic-layer, catalog, machine-learning, and workflow tools. Airflow, Dagster, and dbt integrations can trigger analytical flows and app runs from data pipelines. Hex says its agent grounds answers in organizational context and can connect with Claude, Codex, Cursor, Slack, MCP, a CLI, APIs, or custom agents. Users can build apps from prompts, with code underneath and controls for the finished app. Context Studio and Evals provide visibility into topics, trends, and warnings about answer quality. Community is free; Professional costs $36 a month per Editor, and Team costs $75 a month per Editor. Community and Professional allow up to five published apps, while Team and Enterprise allow unlimited published apps. A 14-day trial is listed.

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.
