Squawk is a linter for Postgres migrations and SQL that catches statements which could cause downtime, such as blocking locks or breaking schema changes. It ships as a CLI (npm, pip, binaries, Docker), a WASM playground, a VSCode extension with a language server, and GitHub Action/App integrations.

Use cases

• lint postgres migration files before deploying
• prevent downtime from ALTER TABLE statements that take exclusive locks
• check SQL for unsafe index creation without CONCURRENTLY
• enforce best practices like timestamptz and identity columns in schema
• add migration linting to pull requests via GitHub Actions
• lint SQL files in CI to catch risky schema changes

When to choose

• your team runs Postgres with SQL migration files and wants to avoid migration-caused outages
• you want automated review comments on schema changes in pull requests
• you need editor feedback on SQL migrations via VSCode or a language server

When to avoid

• you use a non-Postgres database whose locking behavior differs
• your migrations are generated by an ORM and you cannot act on raw SQL warnings
• you need a full SQL formatter or query optimizer rather than a safety linter
