In their own words
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.
