Measured entry

kibo-cursor

cursor-effectminimal-flatmotion on file

A small React composition for rendering a decorative pointer with an attached name and message label. It ships as a shadcn registry TSX file, styles itself with Tailwind utilities, and imports the usual cn helper backed by clsx and tailwind-merge. It has no provider or runtime service dependency.

Verdict

A focused presentation primitive for collaborative presence, with clean subcomponents and no provider burden. It builds and mounts on its own, but it is not a cursor system: movement, participant state, positioning, and motion all remain application work. Watch the non-wrapping label on narrow screens.

Use it if

  • You need collaborator cursors or presence labels in a shared canvas, editor, or review surface.
  • You want separate pointer, body, name, and message primitives that can be recolored and composed per participant.
  • Your interface already uses Tailwind and a cn-style class merging helper.

Skip it if

  • You need cursor tracking, interpolation, presence state, or animation logic included rather than supplying that behavior yourself.
  • Your labels must wrap cleanly inside narrow mobile layouts, since the body deliberately keeps its content on one line.
  • You need the cursor content to be interactive, because the wrapper disables pointer events.
  • You are avoiding Tailwind utility classes and do not want to translate the styling.

In a non-shadcn project, add Tailwind CSS and a cn class-merging helper using clsx and tailwind-merge, then replace or configure the source alias used by the helper import. Copy the React component file into your project. No provider setup is required.
