  description

  PixelProof turns any website into a pixel-perfect QA playground. Click any element to see its full style breakdown, measure pixel distances between elements, and compare live CSS against your Figma design — without leaving the page.
  
  What it does
  
  • Inspect any element with one click — dimensions, spacing, typography, colors, shadows, radius.
  • Measure exact pixel distances between two elements, like Figma's Inspect mode.
  • Paste CSS from Figma Dev Mode and PixelProof highlights every mismatch in red.
  • Copy CSS selectors, HEX codes, and background values with one click.
  • Toggle on/off with Alt+Shift+P (Ctrl+Shift+P on Mac).
  • Drag the panel anywhere, or collapse it when you don't need it.
  
  Who it's for
  
  QA engineers verifying pixel-perfect builds. Frontend developers debugging spacing. Designers checking how their work shipped. Anyone who has ever opened DevTools just to measure a margin.
  
  Privacy
  
  PixelProof does not collect, transmit, or store any data. No accounts, no tracking, no analytics. The "activeTab" permission is used only to read computed styles from the element you click — and only when you trigger the inspector yourself. Everything runs locally in your browser.
  
  How to use it
  
  1. Click the PixelProof icon or press the shortcut.
  2. Click any element on the page to inspect it.
  3. Hover over other elements to see distances.
  4. Paste Figma CSS into the validator to verify accuracy.
  
  That's it. No setup, no login.
