OpenMetadata review

Open-source catalog you own and self-host.

Verdict

OpenMetadata is the wildcard because it delivers discovery, column-level lineage, and governance as open source with a broad connector library, so teams that want to own their metadata avoid a license fee and vendor lock-in.

What customers praise

No license fee, an active community, a unified metadata model, and 90-plus connectors give engineering teams a capable catalog they fully control.

What customers criticise

You carry hosting, upgrades, and support yourself, and the polish and enterprise governance depth trail commercial leaders like Collibra.

Best for

Engineering-led teams that want a free, open-source catalog with discovery, lineage, and governance they self-host and control.
