Most designers and developers juggle 4-5 tools to inspect websites: ColorZilla for colors, WhatFont for typography, a contrast checker, DevTools for CSS.
Designer Toolkit combines them into one extension. Pick colors in any format, grab font details, check WCAG compliance, simulate colorblindness, and copy computed styles - without switching tabs.
Not reinventing the wheel. Just putting the tools you already use in one place, with a history that saves everything automatically.
