OpenMetadata

L3 — Unified Semantic Layer Data Catalog Free (OSS) / Collate managed Apache-2.0 · OSS

OSS unified metadata platform with data discovery, governance, observability, and lineage. Apache-2.0. Connectors for 75+ sources (Snowflake, BigQuery, dbt, Airflow, Tableau). Strong fit as a modern alternative to DataHub/Atlas.

AI Analysis

OpenMetadata is the OSS unified metadata platform with data discovery + governance + observability + lineage — Apache-2.0 license. 75+ source connectors. Collate (commercial managed) provides BAA + SOC 2. Pick OpenMetadata for modern alternative to DataHub/Atlas where glossary + lineage UX are the value prop.

Trust Before Intelligence

OpenMetadata's strength is unified metadata governance — discovery + lineage + glossary + observability + ownership in one platform. From a Trust Before Intelligence lens, this concentrates trust-relevant data into a single coherent surface vs scattered tools. Trade-off: complexity of running a unified platform; Collate signs BAAs.
