DataHub is an open-source metadata platform that its maintainers describe as a context platform for data and AI. It ingests metadata from a wide range of integrations and builds a graph that supports natural-language search, column-level lineage, data profiling, a business glossary, ownership tracking and access policies. Context can be served to people and AI agents through MCP, GraphQL, APIs or SDKs. The project started at LinkedIn in 2019 and can be run as self-hosted DataHub OSS, with a Docker quickstart and Kubernetes deployment, or as the managed commercial offering DataHub Cloud.
The software is published under the Apache License 2.0. The company behind the commercial offering is shown as Acryl Data, Inc. in the site's copyright notice. For DataHub Cloud, the vendor provisions your instance and offers AWS PrivateLink for private connectivity from an AWS account; the pages consulted do not state where it is hosted or whether a European region exists. Self-hosting DataHub OSS keeps metadata and operation under your own control and jurisdiction.
