Is it vibe coded?
Analyze any website to find out whether it was built with AI. Paste a URL, get a score, see the evidence behind it, and take away a prompt that tells your assistant exactly what to fix.
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.
One request, no rendering
We fetch the page server-side, cap it at 2.5 MB, follow at most four redirects, and refuse anything that resolves to a private network. No JavaScript is executed.
45 heuristics, five 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. Generators skip these. Finding them lowers the score.
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.
Read this part. Using a popular framework is not a crime, and a hand-built site can look generated. This is a bit, not a verdict on anyone's craft. Scan your own things first.
