Vibe Coding Detector by A5

Vibe Coding Detector – by A5 Detect when a website was likely created using AI or automated site builders - and see why. Vibe Coding Detector analyzes real, concrete signals in a webpage’s HTML, structure, metadata, and visible copy to estimate how likely the site was “vibe coded.” Instead of sending content to another AI and guessing, this extension uses a deterministic, rule-based scoring model that runs entirely in your browser. You’ll get: • A clear verdict: Likely / Unclear / Unlikely • A confidence score (0–100%) • Specific reasons explaining what indicators were found • An optional debug breakdown for deeper inspection Everything runs locally. No cloud uploads. No tracking. No black-box decisions. Built for developers, researchers, and anyone curious about how modern AI-generated websites leave fingerprints in code and content. Detect signals. Understand patterns. Decide for yourself.
