The models' case: Best overall balance of API-native depth and developer usability: local or CI scanning, strong authenticated coverage, multi-user BOLA/BFLA testing, custom scripts, and. The models' main caveat: Deep coverage still depends on accurate schemas, test data, and authentication configuration. The strongest alternative is Escape — Purpose-built for modern API-first applications (REST, GraphQL, gRPC) using algorithmic sequence generation to test stateful business logic and OWASP. Not unanimous: Gemini picks Escape; Grok picks Escape.
