CSS Scan is built to hover, inspect, and copy CSS from any element in one click, with
lifetime licences and Safari support. Kernline fits when you also need Tailwind classes,
page design tokens, Copy for AI bundles for Cursor or Claude, and component capture as
HTML, React, or Vue, with activeTab permissions only.
