Measured entry

kibo-comparison

feature-gridminimal-flatmotion on file

A client-side before-and-after comparison slider shipped as source through a shadcn registry. It layers two supplied React views with an animated clipping boundary and supports drag or hover interaction. It relies on Tailwind utilities, a shadcn-style cn helper, Motion, and Lucide React.

Verdict

A clean, composable reveal control that builds and mounts without special providers. It is a practical pick for media comparisons, but teams should add keyboard controls and make the surrounding dimensions responsive before treating it as production-ready.

Use it if

  • You need an image or UI before-and-after reveal with either drag or hover behavior.
  • Your React app already uses Tailwind and can absorb Motion and Lucide React.
  • You want composable comparison panels rather than an image-only widget.

Skip it if

  • The comparison must fit a narrow viewport without adapting the fixed dimensions supplied by the caller.
  • You need complete keyboard operation out of the box, since the slider is focusable but has no arrow-key handling.
  • You want to avoid adding a substantial client-side animation dependency for one interaction.

In a non-shadcn project, add Motion and Lucide React, configure Tailwind, provide the background and muted foreground theme tokens used by the classes, and supply a cn utility backed by clsx and tailwind-merge. Keep it in a client-rendered React boundary.
