DataHub describes itself as a context platform for data and AI stacks.
About DataHub
DataHub is an open source context platform for data and AI stacks. It ingests metadata from connected data tools into a unified context graph, which teams can use for search, lineage tracing, and governance. Context can then be served to AI agents through Model Context Protocol (MCP), GraphQL, an API, or an SDK.
The self-hosted open source edition is licensed under Apache 2.0 and provides access to the metadata graph, 150+ integrations, column-level lineage, governance, and discovery. The managed DataHub Cloud product adds data observability, Context Intelligence, Context Hub, and native agent integrations, and the source states that users have no infrastructure to run. Cloud is offered with a free trial, but its pricing is not stated, so known pricing is unknown.
Key features
- Metadata ingestion from 150+ integrations, including dbt, Power BI, Confluence, and Notion
- Column-level lineage for tracing data across the data estate
- Universal search across the data estate using natural language
- Context Activation that serves context to agents via MCP, GraphQL, API, or SDK
- Context Intelligence that builds a semantic index from query history (DataHub Cloud)
- Context Hub where domain experts review and approve AI-proposed context (DataHub Cloud)
Best for: Teams that want full control over their data context platform and are comfortable running their own infrastructure.
