Measured entry

motion-primitives-cursor

cursor-effectdark-futuristicmotion on file

A client-side React cursor replacement distributed as a shadcn registry component. It follows pointer movement with Motion values, can hide the system cursor globally or only over its parent, and accepts custom animation variants. It depends on Motion plus a cn utility backed by clsx and tailwind-merge.

Verdict

A flexible, working cursor primitive for portfolios and immersive demos, with clean mounting and no provider requirement. Use it selectively: the global mode changes the body cursor, and the parent hover listener cleanup should be corrected for long-lived dynamic views.

Use it if

  • You want a branded pointer treatment for a focused interactive demo or showcase.
  • You need either a page-wide cursor replacement or one scoped to a parent region.
  • Your React interface already uses Motion and Tailwind-style utility classes.

Skip it if

  • Your product must preserve familiar native cursor feedback across controls.
  • You want to avoid adding Motion for a small decorative interaction.
  • Your interface is primarily touch-driven, where a custom pointer adds little value.
  • You need strict cleanup of parent hover listeners without revising the source.

In a non-shadcn project, add Motion, clsx, and tailwind-merge, provide a compatible cn helper, replace the path alias if needed, and ensure the utility classes used by the component are available in your styling setup. Keep it client-side.
