Unified metadata platform for modern data discovery and governance
DataHub provides a centralized catalog and real‑time metadata graph, enabling teams to discover, understand, and govern data across the modern data stack with extensible connectors and Kubernetes‑ready deployment.
DataHub is a centralized metadata platform that powers data discovery, lineage, and governance across the modern data stack. It ingests metadata from a wide range of sources via extensible connectors and stores it in a real‑time graph, enabling instant search and impact analysis.
Designed for data engineers, analysts, and governance teams, DataHub can be run locally with a single‑command Docker quickstart or scaled in production using the provided Helm charts on Kubernetes. The platform includes a web UI, GraphQL API, and a suite of actions that react to metadata changes in real time.
Backed by LinkedIn and a growing open‑source community, DataHub is used by enterprises such as LinkedIn, Expedia, and Udemy. Documentation, Slack support, monthly town halls, and a hosted demo environment help teams get up to speed quickly.
When teams consider DataHub, these hosted platforms usually appear on the same shortlist.
