Which to choose

Choose DataHub when AI-agent context, MCP connectivity, federated governance, proactive quality controls, and lineage-assisted incident resolution are central requirements. Choose OpenMetadata when an API-first metadata architecture, standardized schemas, column-level lineage, metadata versioning, and connectors for 100+ services are the stronger priorities. Both provide Apache-2.0 open-source self-hosting.

Best-fit scenarios

Choose DataHub if:

Choose DataHub for organizations building AI-agent workflows around metadata, needing federated policy enforcement, or seeking lineage-based debugging and infrastructure-waste analysis.

Choose OpenMetadata if:

Choose OpenMetadata for teams standardizing metadata through APIs and schemas, integrating many data services, and emphasizing collaboration, versioning, profiling, and column-level lineage.

These scenarios reflect the available product evidence. Your requirements, existing stack, and team expertise should guide the final decision.

Frequently Asked Questions

What is the main difference between DataHub and OpenMetadata?

Both are Apache-2.0 open metadata platforms covering discovery, governance, lineage, quality, and observability. DataHub is positioned around enterprise context management, federated governance, proactive policy enforcement, natural-language metadata queries, and Model Context Protocol connectivity for AI agents. OpenMetadata is positioned around an API-first central metadata store, standardized schemas and APIs, metadata versioning, collaboration, column-level lineage, profiling, and connectors for more than 100 data services.

Which is better for small teams?

For a small team, OpenMetadata can be a strong fit when broad ingestion coverage and a standardized API-first metadata foundation are immediate needs, because its framework supports connectors for 100+ data services. DataHub can be a stronger fit when the team specifically wants AI-agent metadata access, natural-language querying, or lineage-assisted troubleshooting. Both can be self-hosted free under Apache 2.0, so implementation capacity and required integrations should drive the decision.

Can I migrate from DataHub to OpenMetadata?

A migration is possible in principle, but the supplied product information does not describe an official DataHub-to-OpenMetadata migration utility or a guaranteed direct conversion path. Treat it as a metadata re-platforming project: inventory sources, ownership, glossary terms, tags, lineage, quality rules, and governance policies; map them to OpenMetadata schemas; validate connector coverage; then reconcile results before switching users and downstream integrations. API and schema differences require deliberate mapping.

What are the pricing differences?

DataHub offers free Apache-2.0 self-hosting and a free Professional tier limited to up to 20 saved searches and daily email alerts. Its Enterprise tier requires a sales quote; the supplied information does not publish a dollar rate, usage meter, or contract minimum. OpenMetadata is free and open source under Apache 2.0 for self-hosting. The supplied OpenMetadata pricing information lists no paid tiers, metered usage, or public rate card.
