Originally developed at LinkedIn, DataHub is the leading open-source platform for data discovery and observability. It acts as a "Search Engine" for your company's internal data assets.
### Features
* **Full-Stack Lineage**: See how your Airflow tasks, dbt models, and Looker dashboards are connected.
* **Impact Analysis**: Before you change a column name in your database, DataHub tells you exactly which downstream reports will break.
* **Collaboration**: Users can "verify" datasets, add documentation, and subscribe to alerts when a specific table is updated.
**Best for**: Engineering-heavy teams that want a "single source of truth" for their data metadata without paying for expensive enterprise SaaS seats.
