Design Tool

What is Design Tool?

Hover any element on a live website and read its type styles the way you would in Figma. Click two elements to measure the exact gap between them as dimension lines, not a ruler you eyeball. See margin, border and padding as a spacing box instead of a flat CSS list. Reach past full-bleed overlay elements with a Cmd/Ctrl-hover. No host permission, no tracking, no network requests — nothing leaves your browser.
