Measured entry

kokonut-card-stack

carddark-futuristicmotion on file

An interactive product-card stack that expands and collapses on click, with spring motion and reduced-motion support. It ships as a client-side shadcn registry component for Next.js and relies on React, Motion, Next Image, Tailwind utility classes, and a shared cn helper.

Verdict

A polished interaction concept with sensible reduced-motion handling and a clean accessibility scan, but it is not drop-in. It needs a shadcn-style setup, its mobile spread needs correction, and the supplied image wiring needs attention before production use.

Use it if

  • You need a compact, tactile way to preview several product or plan cards in one focal area.
  • Your app already uses Next.js, Tailwind, and shadcn-style aliases and utilities.
  • You can replace the sample products and image sources with controlled application data and assets.

Skip it if

  • Your layout must remain overflow-free on narrow phone screens without responsive rework.
  • You need every card's details visible or directly reachable without toggling a layered stack.
  • You want a lightweight static card treatment and cannot justify the added animation dependency.
  • You cannot replace or correctly configure the demo image sources, which produced failed resource requests in the harness.

Providerno provider required in the harness

In a non-shadcn project, add Motion and provide React client-component support, Tailwind utilities and dark-mode styles, the cn class-merging helper, and Next Image support or a standard image replacement. Supply the missing local artwork, allow any remote image hosts, and adapt the fixed card geometry for narrow screens.
