Why not a raw SQL linter

Built for how your ORM actually ships schema.

01

ORM-aware engine

Understands Prisma and Drizzle migration structures, catching framework-specific bugs standard SQL linters miss.

02

Zero-trust security

Operates entirely via static AST parsing. It never connects to your live production or staging databases.

03

Inline PR feedback

Automatically posts a clean markdown hazard report directly to the GitHub Pull Request during code review.
