Aceternity UI
132 motion-heavy React sections; 329 registry items; 17 paid templates
Aceternity UI is a library of visually maximal React/Next.js sections built on Tailwind CSS and Framer Motion — aurora and beam backgrounds, 3D card tilts, macbook scroll, globes, sparkles, parallax heroes, shader canvases. The docs list 132 components and the registry.json exposes 329 installable items once premium blocks are counted; installation is the standard shadcn CLI against an `@aceternity` namespace. On top of that sit 17 full templates (agency, SaaS, AI-agent, portfolio) and 200+ premium blocks behind a one-time or annual licence. It is built for marketing sites and launch pages, not for application UI.
npx shadcn@latest add @aceternity/sidebarReach for Aceternity when the ask is a landing or launch page that has to look expensive — aurora backgrounds, hero parallax, 3D pins, macbook scroll — not when the ask is a dashboard or a form-heavy app; every component drags in Framer Motion and most animate on scroll, so bundle size and CLS get worse fast. It installs through the same `npx shadcn@latest add` CLI (namespaced `@aceternity/...`), so it drops cleanly alongside shadcn/ui in one project, but check first whether the specific component is free or premium: pulling a premium block without a licence will fail or give you a stub. Add `prefers-reduced-motion` handling yourself — these components do not claim accessibility, and a page of them is a genuine vestibular problem.
Why it is here. It defined the current visual dialect of AI-startup landing pages, so knowing it is knowing what 'looks modern' means to most clients right now.
