About PeekCSS

PeekCSS is a CSS inspector — hover any element to read its computed styles instantly, no DevTools required. Free, no account needed: hover + click inspection, grouped CSS with copy, contrast ratio badges (AA/AAA), and basic color/font info. Free account unlocks: full page color palette, complete fonts panel, and accessibility scoring and one-click-download for all images. Pro adds palette export (CSS/SCSS/JSON/Tailwind), font pairing suggestions, asset downloads with "download all" ZIP. Privacy-first: nothing about the pages you inspect ever leaves your device. The only network call is an optional license check if you've purchased Pro.
