Coalesce Catalog vs DataMerlin

Coalesce Catalog is a data catalog for discovering, documenting, and governing assets across a data stack. Its AI-assisted natural-language search covers domains, dashboards, tables, and columns, while automated lineage maps data from sources to BI tools at column level. A metadata-powered semantic layer supports collaborative cataloging and documentation. Governance features include access monitoring and control, sensitive-data classification, role-based controls, and audit trails. Integrations span warehouses, databases, BI tools, and services including Snowflake, Databricks, BigQuery, Tableau, Power BI, dbt, Slack, and Okta. Coalesce says it can document up to 90% of a database in seconds by propagating material from connected tools. Its Public API can read and update metadata such as tables, columns, dashboards, lineage, and quality tests. The free Developer plan includes one user, one project, one environment, and 2,000 monthly actions. Starter costs $150 a month, billed annually, and includes three Catalog integrations. Coalesce lists web and API platforms.
