A Aceternity UI alternative for animated React components
Aceternity UI and Nexus UI both give you animated React components you add to your own project. Here is how they differ, and when Aceternity UI is the better fit.
| Aceternity UI | Nexus UI | |
|---|---|---|
| What it is | A library of copy-paste React components, blocks, templates and landing pages. | A library of animated React components, blocks and Next.js templates. |
| Stack | React, Tailwind CSS and Motion, for Next.js, TanStack Start, Vite and React Router. | React, TypeScript, Tailwind CSS and Framer Motion. |
| Install | Copy and paste, or install through the shadcn CLI. It also lists adding blocks through an AI agent connected over MCP. | Copy from each component page, or install with the shadcn CLI through the @nexus-labs registry. |
| Free | 118+ free components, as it states. | 68 of 175 components, 2 of 22 templates and the free blocks. |
| Paid | Its All-Access pass unlocks the premium components, 182+ blocks and 17 templates it lists, as a one-time payment with lifetime access. We did not find a price on its homepage. | Pro is $49.99 a year, or All-Access is $79.99 once. Either unlocks the 107 Pro components, all 22 templates and the premium blocks (21 block groups in total), plus Pro build prompts. |
Choose Aceternity UI if
- You want the largest set of ready-made blocks and templates it lists, and you are happy with a one-time pass.
- You want to add blocks through an AI agent over MCP, which it describes on its homepage.
Choose Nexus UI if
- You want one plan that unlocks every Pro component, block and template, with the choice of a yearly or a one-time payment.
- You want springs and physics-driven components, and full-page Next.js templates, in the same library.
- You install with the shadcn CLI and want Pro build prompts an AI coding agent can work from.
What we say about Aceternity UI comes from ui.aceternity.com as we read it in October 2026, and it may have changed since. Anything its homepage did not state is left out. Nexus UI is independent and not affiliated with Aceternity UI.
