Editor's Summary · Data Catalog Software
Data catalogs divide on how much curation they expect from you. Alation, Collibra and Microsoft Purview are enterprise governance platforms where the catalog is one module — powerful, but they assume a governance team exists to run them. Atlan, Select Star and Secoda automate more of the documentation and lineage, which suits teams who want the catalog populated without assigning someone to it. OpenMetadata and DataHub are open source, free to self-host, and now the default choice for engineering-led teams.
Two specialists are worth separating out: Solidatus for regulated financial services where lineage must satisfy BCBS 239 and DORA, and Dataedo for mid-size organisations starting governance without enterprise budget.
This category overlaps data governance deliberately; several products appear in both.

How to choose Data Catalog Software
If nobody will own curation, filter for platforms that auto-generate documentation and lineage. If you already run a governance programme, an enterprise suite will consolidate more tooling. If budget is the constraint and you have engineering capacity, the open source options are genuinely competitive. If you are in regulated finance, lineage evidence for BCBS 239 or DORA narrows the field quickly.
