Aceternity UI

Overview

Aceternity UI is a copy-paste component library: there is no aceternity runtime package. Each component is a source file served from a shadcn-compatible registry at ui.aceternity.com/registry/<name>.json; the shadcn CLI writes it into components/ui/ and installs its dependencies, so you own and edit the code. Free components are installed this way; the site also sells a paid "Pro" set of templates and blocks, which is outside this skill.

Components are built with Tailwind CSS and, for most animation, the motion package (the successor of framer-motion; imports come from motion/react). Registry entries use the @/lib/utils cn helper, so a shadcn-initialised project is the easiest base.

Instructions

1. Prepare the project

npx shadcn@latest init          # creates components.json and lib/utils.ts (cn helper)

Register the namespace in components.json (needs shadcn CLI 3.x):
