  Can you tell if a website was vibe coded?
  
  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. Click the icon for the full breakdown.
  
  ⚡ VIBE SCORE — 0 TO 100
  A single number that tells the whole story:
  
    0–20   → Human Crafted — built with care, minified, no AI slop
    21–45  → AI Assisted — solid bones with some AI help
    46–70  → Mostly Vibed — the starter kit is showing
    71–100 → Pure Vibe Energy — deployed to Vercel in an afternoon
  
  🧠 WHAT IT DETECTS
  VibeCheck analyses 15+ signals including:
    • AI phrases detected in page source
    • Unminified / unoptimised code
    • Placeholder or boilerplate content left in
    • Hosting platform (Vercel, Netlify, Railway, etc.)
    • Missing accessibility attributes
    • Generic or AI-named CSS classes
    • Console errors on page load
    • Duplicate component patterns

  Vibe-Code Checker — Website Analysis Tool
  
  Vibe-Code Checker analyzes webpage technical characteristics to provide insights into how a website may have been built. It generates a Vibe Score (0–100) based on observable signals such as code structure, common patterns, and technology indicators.
  
  The extension is designed to help users explore website composition and development approaches. It does not make definitive claims about whether content is AI-generated or human-created.
  
  Vibe Score Overview
  
  0–20 → Structured and optimized code patterns
  21–45 → Mixed patterns with assisted tooling
  46–70 → Repeated or template-based structures
  71–100 → Strong presence of automated or generated patterns
  
  Analysis Signals
  Includes detection of factors such as unminified assets, repeated code patterns, placeholder elements, accessibility markers, and general structural indicators.
  
  Technology Detection
  Identifies commonly used technologies and platforms to provide additional context about how a site is built.
  
  Privacy
  All analysis is performed locally in the browser. No data is collected, stored, or transmitted.
