See every raw Tailwind class on the page — instantly

Loupe's Tailwind Xray highlights elements still using raw utility classes and ignores your design system's, so you know exactly what your components should replace.

Migrating a codebase from raw Tailwind to a component library — or just keeping one honest — means finding where px-4 flex gap-2 is still sprinkled through the markup instead of a proper component. Grep only sees source; it can't tell you what's actually rendered. Loupe is a Chrome extension that highlights raw Tailwind utilities right on the live page.

How Tailwind Xray works

  1. Enable Loupe on any page (click the icon or Alt+Shift+K).
  2. Press S for Tailwind Xray. Loupe scans every element and highlights the ones carrying raw Tailwind utility classes.
  3. Hover a highlight to see exactly which classes matched.
  4. Add your brand prefixes to the allowlist — Loupe skips your design-system classes so only the raw utilities that need replacing stay lit up.

Why it's useful

Goes further: design-system profiles

Load a design-system profile and Loupe graduates from "raw Tailwind" to full token awareness — inspect any element to see which design token it uses, inventory your components, and (Pro) lint the whole page for raw colors, rogue spacing, and deprecated tokens.
