DataFlint OSS

Drop-in performance monitoring tab for Apache Spark's Web UI.

Pluginfreemium

DataFlint OSS is a plugin that adds a modern performance-monitoring tab to Apache Spark's Web UI, showing query breakdowns, a performance heat map, run summaries, and alerts. It installs on the Spark driver or history server without changing the existing environment and works across Kubernetes, EMR, Dataproc, and Databricks deployments. Built for data engineers who find the stock Spark UI hard to navigate.
