Measured entry

shadcn-hover-card

tooltipunclassified

A copy-in React hover card built on Radix UI primitives. It ships as a client component with root, trigger, and portalled content wrappers, and relies on the radix-ui package, a local cn helper, Tailwind utility classes, theme tokens, and animation utilities.

Verdict

A sound choice for an existing shadcn-style interface: it builds, mounts, and keeps Radix behavior easy to customize. It needs a shadcn-style setup and does not work as a bare drop-in because the local utility import and styling conventions must exist.

Use it if

  • You need a compact preview panel that opens from a link or profile trigger.
  • Your app already uses the shadcn utility, theme-token, and Tailwind conventions.
  • You want Radix to handle the trigger, portal, placement, and open-state behavior while keeping the wrapper editable.

Skip it if

  • You only need a short text hint, where a tooltip is the clearer pattern.
  • Your product is primarily touch-driven and has no dependable hover interaction.
  • You do not want to adopt or translate shadcn Tailwind classes, theme tokens, and animation utilities.
  • You need a self-contained package with no project-local utility import.

In a non-shadcn project, add React and the radix-ui package, provide a compatible cn class-merging helper or replace that import, configure Tailwind, define the popover and border theme tokens, and include utilities for the state and directional animations used by the content.
