Is it vibe-coded?

Find the fingerprints. Catch the oversights. Choose a vibe check, passive security check, or launch checklist — and leave with evidence and a repair brief for your coding assistant.

AI-builder fingerprints, design conventions, and a repair prompt. A heuristic reading, not proof of authorship.

How the scan works

There is no language model behind the score. It is a deterministic pattern matcher, which means it is fast, free, repeatable, and confidently wrong sometimes.

  • Public evidence, bounded requests

    One request for the public page, capped at 2.5 MB. We never execute the page’s JavaScript, and nothing is stored.

  • 94 heuristics, eight categories

    Stack fingerprints, house aesthetic, copy tells, and leftovers push the score up. Every one carries a weight and has to show its evidence.

  • Craft pulls it back down

    Skip links, real ARIA, self-hosted fonts, a token layer, structured data. Finding these lowers the vibe score, but does not prove who built the page or whether it works.

  • Then you get a fix list

    Every finding carries a remedy. The prompt we hand you is a repair brief — remove these, add these, and here are the rules so you don't just land on a different default.
