Open source and free tools

Onehouse’s founder, Vinoth Chandar, created Apache Hudi at Uber, where it still runs in production. Onehouse originated Apache XTable (Incubating), which translates metadata between Hudi, Iceberg, and Delta Lake. Both projects are governed at the Apache Software Foundation and can be used independently of the commercial product. Onehouse engineers lead both projects. The commercial platform ships on its own release train.

These free tools work before you deploy anything:

Tool	What it does
LakeView	Observability for Hudi tables, whether or not you run Onehouse
Spark Cost Analyzer	Reads your Spark history server and reports optimization opportunities
Quanton Operator	Drop-in replacement for the Kubeflow Spark Operator, running Quanton on your own Kubernetes
