OneSync™
Write your data once, then query anywhere. OneSync brings a single copy of data and access control policies to all your catalogs and engines.

Write data once, query anywhere with full permissions enforcement.
Modern data teams don't live in one platform. Your engineers run pipelines on AWS, data scientists model in Databricks, analysts report through Snowflake, and BI teams have moved to Microsoft Fabric. The result: redundant data copies, fragmented access controls, and a governance nightmare that grows with every new tool you adopt.
OneSync™ eliminates that complexity at both layers. First, it syncs table metadata across all your catalogs — Snowflake, Databricks Unity Catalog, Google Data Catalog, AWS Glue, and more — so a single copy of your data is instantly queryable from any engine. No duplication, no ETL rework, just write once and query everywhere.
For data governance, OneSync Permissions translates access control policies across catalogs automatically — so the permissions you define in one catalog propagate consistently to every other platform your team uses.
The result is a true Universal Data Lakehouse: open formats, open catalogs, and a governance model that actually travels with your data rather than breaking down the moment someone switches query engines.

A single consistent view for every query engine
Ingest and transform your data with Onehouse, then sync to Glue Catalog, Unity Catalog, Snowflake Catalog, and more with OneSync. Syncs run automatically to keep your table views consistent in each catalog.
