Rocky

SQL transformation engine that type-checks data pipelines and catches breaking changes before they run.

Desktopfree

Rocky is an open-source SQL transformation engine that type-checks an entire data pipeline and catches breaking changes, such as schema drift or a dropped required column, before they run. It works with existing SQL on Databricks, Snowflake, BigQuery or DuckDB and adds column-level lineage, branching and replay. It also includes policy controls so AI coding agents can propose pipeline changes without being allowed to apply them unreviewed.
