In their own words
Coalesce Catalog
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.
OpenDataDiscovery Platform
OpenDataDiscovery Platform is an open-source catalog for finding and governing data products across data teams. Search and facet filters help users locate metadata by source, owner, or tag, then explore ownership and related links. The platform traces data objects and microservices end to end, imports data quality test results, and shows dataset quality status. It also catalogs machine-learning experiment metadata and lineage and supports experiment logging, connecting data science and data engineering work. Teams can access collected metadata through a web interface or REST API, and deploy with Docker Compose, Kubernetes and Helm charts, or AWS Marketplace QuickLaunch. The catalog uses an open metadata collection standard to connect catalogs, tools, and feature stores; Lookup Tables support reference data governance. ODD supports LDAP authentication and USER and ADMIN roles. Its documentation cautions against simple login-form authentication in production. Metadata attachments are limited to 20 MB, while links can point to larger or remotely stored files. The platform is free and open source, with public development.
