VraieSource

VraieSource is an open prototype tool that helps data teams explore how proposed database schema changes could affect downstream charts and reports. It features an interactive SQL playground to simulate schema migrations, inspect dependencies, and review suggested fixes to prevent breaking reports. Currently, it works with supplied SQL schemas and metadata and simulates repositories and reporting tools like Metabase and Looker Studio. It targets small teams needing to catch schema-resilience issues in data stacks.
