Overview

Welcome to the Kerno documentation.

What is Kerno?

Kerno is runtime code and security review for coding agents. It gives your agent an independent reviewer that lives inside the session and runs against your real stack, so the code it ships works as part of your system as intended.

Kerno runs locally. Your coding agent drives it over MCP, an optional IDE extension shows you what it is doing, and the portal reports across your team.
