Kerno 1.0

Kerno 1.0: Kerno is an AI backend runtime quality assurance tool that writes and executes tests against live applications and real dependencies.

Kerno is an AI backend runtime QA engineer designed to test critical user flows locally against real stacks. It maps codebases, builds dependency graphs, and runs end-to-end tests across APIs, background tasks, and message queues. The platform validates contracts, authentication, authorization, OWASP Top 10 security issues, boundary cases, and error handling. It also tests Model Context Protocol servers and AI agents by mocking model providers for deterministic runs. Kerno connects over MCP to coding agents like Claude Code, Cursor, and GitHub Copilot, providing structured signals on every code change.
