DataHub
An open-source metadata platform for data discovery, governance, and observability across your entire data and AI stack.
What is DataHub?
DataHub is an open-source metadata platform that acts as a centralized catalog for discovering, governing, and observing data across complex data and AI stacks. It solves the challenge of fragmented data tools by creating a unified, real-time metadata graph that connects warehouses, lakes, BI platforms, and ML systems.
Data engineers, data platform teams, and data stewards at organizations with complex, multi-tool data ecosystems who need to manage metadata at scale.
Developers choose DataHub for its battle-tested scalability from LinkedIn, real-time streaming architecture, extensive connector ecosystem, and native AI agent support via MCP, all available under a permissive Apache 2.0 license.
