Measured entry

magicui-marquee

carouselunclassifiedmotion on file

A React and TypeScript marquee that repeats arbitrary children in a continuously moving row or column. It ships as a shadcn registry component and uses Tailwind utility classes, project-level marquee keyframes and animation tokens, plus the usual cn helper imported through the project alias.

Verdict

A compact, flexible marquee for shadcn-based React projects, with a clean verified mount and no detected accessibility violations. Narrow-screen overflow needs review, and it needs a shadcn-style setup rather than working as a bare drop-in.

Use it if

  • You need a looping strip for logos, short labels, images, or video thumbnails.
  • You want reverse, vertical, and pause-on-hover behavior controlled through component props.
  • Your project already follows shadcn conventions and can absorb registry CSS tokens.

Skip it if

  • The moving content must stay fully contained on narrow screens without additional layout work.
  • You need meaningful content announced only once, since repeated children can create duplicate reading and focus targets.
  • Your stack does not use React, Tailwind utilities, or shadcn-style path aliases.

In a non-shadcn project, add a cn class-merging helper at the expected project alias or change the import, provide the Tailwind utility styles used by the component, and define the horizontal and vertical marquee keyframes and animation tokens in the global theme.
