Use this page to decide whether supaschema fits your schema workflow. supaschema reads PostgreSQL schema intent from SQL files, compares it with another schema source, renders replay-safe migration SQL, refreshes TypeScript types and Zod validators, and can apply pending migrations through guarded sync targets. It removes the need for an ORM schema layer, Docker, or a shadow database in the schema workflow.

​
When it helps

  • Your repository should be the source of truth for PostgreSQL schema changes.
  • You want migrations that can be retried safely after a failed deploy.
  • You need policy, type, and generated-output changes visible before a database catches up.
  • You want typed, validated application boundaries without making an ORM the schema owner.
  • You use plain PostgreSQL or a hosted provider such as Supabase, Neon, RDS/Aurora, Cloud SQL, AlloyDB, or Azure PostgreSQL.

​
Workflow

supaschema workflow that parses schema files, renders a guarded migration, emits TypeScript and Zod outputs, and hands SQL to the database runner
You edit schema files. supaschema diff renders the migration and configured generated outputs. supaschema check verifies replay-safety. supaschema sync can run the guarded apply lane when you select a target or configure approved automatic targets. For detailed performance, accuracy, and replay-safety results, see Benchmarks.
