The Bottom Line

There's no single "best" tool — it depends on your workflow.

  • Quick color grab? ColorZilla is fine.
  • Just identify a font? WhatFont does the job.
  • Nice visual inspector? CSS Peeper is beautiful.
  • Full design system + dev exports? BrandSpy fills that gap.

If you're a developer who needs Tailwind configs or CSS Variables export, BrandSpy offers something the extensions don't. If you just need a quick inspection, the free extensions work great.
