Vibe-Code Checker

Detect AI vibe-coded websites and analyze their tech stack

VibeCheck scans any site you visit and gives it a Vibe Score from 0 to 100 — instantly telling you how much of it was AI-generated vs hand-crafted by a real engineer. 🔍 HOW IT WORKS Install VibeCheck and just browse normally. It automatically scans every page in the background and updates the extension badge with the site's Vibe Score.
