Kerno Audit - Track AI's impact on your codebase quality & complexity

Hey Everyone!

I'm excited to launch Kerno Audit today!
It's the tool we built to put together our report, The Impact of AI on Code Quality 2026, which tracks how AI coding is changing open-source codebases.

Now you can run the same audit on your own codebase. Kerno Audit compares your code before and after your team adopted AI, and shows you where quality slipped across five areas:
