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.
Grai
Grai is a data lineage tool for tracing and testing relationships among databases, warehouses, APIs, and dashboards. It can automatically build column-level lineage across warehouses and production services. Centralized validation tests run when upstream data sources change, and GitHub Actions can alert CI/CD workflows when production changes affect warehouses or dbt projects. Listed connectors include Snowflake, BigQuery, Redshift, Postgres, MySQL, SQL Server, dbt, Fivetran, flat files, Metabase, and Looker; the Looker connector is marked alpha. Grai describes itself as open source and self-hostable, with Docker Compose and Kubernetes examples and Helm charts. Grai Cloud is available to run for free. The frontend is a React web application, and the CLI is a Python client for the Grai server. The repository lists an MIT-0 license. The privacy policy says Grai collects email addresses, cookies, and usage data, and names AWS and Google Cloud Platform among its service providers. It says commercially acceptable measures are used to protect personal data but cannot guarantee absolute security. The repository lists [email protected] and points to Slack and a community roadmap for requests and bug reports.
