Calibrly - Upload an HTML file and inspect every pixel of it

Calibrly is a browser-based inspection tool for HTML files. Upload a file and inspect spacing, typography, colors, the box model, and WCAG contrast ratios — then export what you find as computed CSS or Tailwind utility classes. No install, no extension, no DevTools digging. Built for developers and designers who need to check someone else's markup fast. Free plan: 5 uploads per month.
