Generate. Validate. Ship.

What is Kerno?

Kerno is a validation engine that helps you catch breaking changes in your AI backend code before raising your PR. It automatically generates, runs, and maintains high-quality integration with full codebase context.

When you make changes, Kerno validates them against your real service and dependencies to catch breaking changes and unintended side effects. All directly in your IDE with instant feedback.

Key Benefits

• For Developers: Ship faster with zero manual test writing. Get feedback in minutes instead of hours without ever leaving your IDE.

• For Team: Achieve predictable quality and accelerate release cycles. Ensure consistent coverage across your backend codebase while eliminating manual QA bottlenecks and test maintenance overhead.
