The web doesn't need more AI-generated sameness. Ship something that looks like you built it.
HOW IT WORKS
Submit any URL. We take a full-page screenshot, run headless Puppeteer, and score 45+ visual + structural heuristics across 5 categories. Output: 0–100, where higher = more AI-vibe.
WHAT WE GRADE
Look, not code. Purple gradients, uniform padding, card grid syndrome, hero-stat-FAQ scaffolding, AI copy tells, default icon libraries, palette homogeneity. We grade the vibe, not the toolchain — tasteful AI-coded sites pass.
OPEN SOURCE
VibeCheck is fully open. Run it locally, add it to your CI pipeline, or use it as a Claude Code skill. The detection algorithms are transparent — no black boxes.
