Was It Vibed?

Was it built,
or prompted?

We check public websites for 46 patterns associated with vibe-coded and AI-generated work. Deterministic pattern matching, not an AI classifier.

Results are saved and get a public link that can appear on the leaderboard and in search engines. Scanning a site you do not own publishes a judgment about someone else's work. How to get a result removed.

A score with receipts

A single gradient or utility class proves nothing. The detector looks for corroborating evidence, caps weak results, and publishes the rules behind every score.
