DriftGuardAPI Type Safety

Enforce API type safety across OpenAPI, GraphQL, and gRPC — catch breaking changes before they reach production.

Multi-schema support

Parses OpenAPI 3.x (YAML/JSON), GraphQL SDL, and Protobuf (.proto) schemas.

Every change is classified as breaking, non-breaking, or info — with detailed rules per schema type.

Posts PR comments with the full diff, updates a drift log on GitHub Pages, and supports --fail-on-breaking to block merges.

Use drift-guard programmatically from Node.js/TypeScript via @pgomes13/drift-guard, or import pkg/compare and pkg/impact directly in Go.
