  Figma Validator — Validate Your UI Against Figma
  
  Figma Validator is a design QA assistant that helps you compare your live frontend with Figma designs and quickly spot what’s visually off.
  
  It works alongside the Figma plugin to bridge the gap between design and implementation.
  
  🚀 How It Works
  
  1. Open your live website
  Navigate to the implemented page in your browser.
  
  2. Click “Pick Area”
  Select the exact UI section you want to validate.
  
  3. Match it with Figma
  Connect it with the selected frame from the Figma plugin.
  
  4. Review Visual QA
  Instantly see what looks different.
  
  5. Switch to Dev (if needed)
  Get deeper debugging and fix guidance.
  
  👀 Visual QA (Default Experience)
  
  Focus on what users actually see:
  
  Spacing issues
  Alignment problems
  Size differences
  Text mismatches
  Typography & style inconsistencies
  
  When confidence is high, get clear fix suggestions, like:
  
  “Reduce gap from 12px to 8px”
  “Align element to top”
  “Fix letter spacing to 0px”
  🛠 Dev Mode (Advanced)
  
  For deeper debugging:
  
  DOM ↔ Figma node mapping
  Unmatched element detection
  Candidate matching insights
  Style and text diagnostics
  Tree-aware debugging
  ⚠️ Requirements
  
  This extension works only with:
  
  ✅ Figma Validator Plugin (in Figma)
  
  Both must be used together for full functionality.
  
  💡 What Makes It Different
  
  Figma Validator is not:
  
  A CSS inspection tool
  A raw DOM comparison tool
  A pixel-perfect auto-fixer
  
  It is:
  
  👉 A visual-first QA assistant
  that helps you find design drift fast and fix it confidently
  
  🎯 Perfect For
  Frontend developers
  UI engineers
  Designers validating implementation
  Teams doing design QA before release
  ⚙️ Built With
  Chrome Extension (Manifest V3)
  DOM APIs
  Canvas-based visual comparison
  TypeScript / JavaScript
  🔗 Workflow Summary
  Run plugin in Figma
  Open your site
  Use “Pick Area” in extension
  Review Visual QA

  Figma Validator helps developers compare implemented UI with Figma designs directly on live webpages.
  
  Select an element in Figma, then Shift+Click on the webpage to instantly validate:
  
  • Spacing (margin/padding)
  • Typography (font size, weight, line height)
  • Colors (text/background)
  • Border radius
  
  Results are shown in a visual comparison panel highlighting mismatches and matches in real time.
  
  Built for frontend developers to reduce manual inspection time and ensure pixel-accurate implementation.
