Unity Catalog pricing.

Open core free to self-host · paid managed tiers

The model

How free forever pricing works.

How it's charged

The software is free, full stop — an open-source project with no commercial tier behind it. Your real costs are infrastructure and the engineering time to deploy, upgrade, and operate it.

What to watch

Total cost of ownership. Free software with a weekend of setup and a day a month of upkeep is not free — budget the operational load, and check project governance for long-term maintenance signals.

Alternatives by price

Same cluster, ranked by entry cost.

Amundsen OSS · free The Lyft-born OSS catalog that invented search-first discovery — historically important, but development has largely stalled since 2024. pricing vs Unity Catalog
Apache Atlas OSS · free The ASF's Hadoop-native metadata framework — typed entities, classification propagation via lineage, and Ranger-enforced policies. pricing vs Unity Catalog
DataHub OSS · free Apache-2.0 metadata platform with a serious managed counterpart — strongest event-driven architecture and column-level SQL lineage in OSS. pricing vs Unity Catalog
OpenMetadata OSS · free Apache-2.0 unified metadata platform with a deliberately simple stack — discovery, lineage, quality, and contracts in one project. pricing vs Unity Catalog
Alation Contact sales The incumbent that defined the data catalog — behavioral search, deep governance, and strong column-level lineage. pricing vs Unity Catalog
Atlan Contact sales Enterprise catalog and governance plane positioned as the AI context layer — connectors, lineage, contracts, and an MCP server for agents. pricing vs Unity Catalog
Collibra Contact sales Enterprise data-and-AI governance incumbent: catalog, glossary, workflow stewardship, lineage, and a separate ML data-quality module. pricing vs Unity Catalog
Secoda Contact sales AI-native data catalog, lineage, and observability from Toronto — acquired by Atlassian in December 2025 to power Rovo AI. pricing vs Unity Catalog
Select Star Contact sales Automated data catalog with column-level lineage parsed from query logs — being acquired by Snowflake to power Horizon Catalog. pricing vs Unity Catalog

Common questions

Asked about Unity Catalog pricing.

Does Unity Catalog publish pricing?

Yes. Unity Catalog is free, open-source software.

Does Unity Catalog have a free tier?

Yes. Open-source under Apache-2.0; self-host. Databricks-managed Unity Catalog is a separate paid offering bundled with the Databricks platform and is out of scope for this entry.

Can you run Unity Catalog for free by self-hosting?

Yes — Unity Catalog can be self-hosted at no license cost. Unity Catalog OSS and Databricks-managed Unity Catalog share a name and a schema model, but they are materially different products in 2026. The managed version on Databricks has automated runtime column-level lineage, fine-grained ACLs, attribute-based access control, audit logs, and PII classification. The OSS has the catalog API, asset model, storage credentials and external locations (added in v0.4), and managed-table support — but lacks lineage, glossary, classification, and most governance UI. Treat them as related but separate products when evaluating.

What's the cheapest alternative to Unity Catalog?

Among the 9 same-cluster alternatives indexed here, Amundsen has the lowest entry cost (oss · free). Ranking is by published entry price; sales-led tools may quote anywhere.
