Description
Aceternity UI is a collection of more than 200 production-ready React and Next.js components, built by developer Manu Arora. The components rely on Tailwind CSS and the Framer Motion animation library and mainly cover visually striking building blocks: hero sections, animated 3D cards, background shaders, bento grids, text effects, and navigation elements. The usual way to bring a component into your own project is copy-paste: every component page provides the full source code directly for copying, with no separate installation step. Some components additionally offer a shadcn-compatible registry command that lets you insert the building block through a CLI command.
The library requires React or Next.js, Tailwind CSS, and Framer Motion as its animation foundation, and a cn helper function in a lib/utils.ts file is expected to exist for many components, as is common in the shadcn ecosystem. Anyone already using a different animation library in their project should not carelessly add Framer Motion alongside it, but instead port components deliberately or keep them isolated. Background shaders such as Aurora or Vortex are GPU-intensive and are only suited to a limited degree for multiple simultaneous uses on one page. The free tier covers more than 200 components; full templates and some premium blocks sit behind a paid All-Access plan.
Compared with pure primitive libraries such as shadcn/ui, Aceternity UI is not a replacement but a complement: shadcn provides the basic building blocks for forms, data display, and overlays, while Aceternity UI provides the visual presence for hero areas, marketing sections, and striking effects. For projects with a restrained, functional brand voice, the library is less of a first choice, because its components default to motion, gradients, and visual effects.
