Dev Design LibraryAnimated Diff Viewer Components
Dev Design Library indexes 9 Animated diff viewer components from 7 open-source UI libraries, with the most coming from Spectrum UI, Kinetics, Kokonut UI, Magic UI and GreatUI. Each one links to its page with the source code, a live preview where available, the library license and the install command. These are the diff viewer components tagged as animated: motion on hover, on scroll or on load, usually built with CSS transitions or Framer Motion. Diff viewer components belong to the Developer tools group.
