Schema Diff Studio is a Cosmovex tool for reviewing database schema changes before taking a migration into your own workflow. Paste Before and After SQL, compare them, and inspect the generated migration and verification result. Comparison and copying SQL are free. Pro adds migration downloads, rollback generation and version history. Verification compares schemas in a fresh database; it does not prove safety with production data or workloads. Which schema change is hardest for you to review: constraints, type changes, or table rebuilds?
