Specter

About this product

Specter turns any webpage into something you can read like a design file. Hover any element to see its spacing, typography, colour, WCAG contrast, borders, and flex/grid layout — in plain, copyable CSS. Load your design tokens and it flags every off-token colour, size, and radius. Plus a live eyedropper with a zoom loupe, full-page screenshots, and :hover/:focus/:active simulation. 100% local, no tracking, free. Built for designers, UX engineers, and front-end devs.
