Kerno.io

An AI backend QA engineer that runs in every coding session against the live application and dependencies to catch regressions and security issues missed by agents and code review. It autonomously writes, runs, and maintains validation suites that verify behavior before merge. It is for software developers and engineering teams in B2B organizations building backend APIs and services.
