Aceternity UI: Animated React and Tailwind CSS Components for Next.js
Aceternity UI pairs Tailwind CSS with Framer Motion so the components you copy in already move. A look at the library, the install path, and where it fits.
Aceternity UI is a React component library that helps you build animated, modern websites without writing motion code from scratch. It pairs Tailwind CSS for styling with Framer Motion for animation, so the buttons, cards, and backgrounds you copy in already move the way you want. If you build portfolios, landing pages, or SaaS dashboards with Next.js, it cuts the time between an idea and a working interface.
Quick highlights
- More than 70 animated components built with React, Next.js, Tailwind CSS, and Framer Motion.
- Add any component by copying the code or running a Shadcn CLI command. Free and Pro tiers are both available.
- Popular for portfolios, marketing pages, and SaaS apps because it removes most of the design and animation work.
- Backed by an active community and tutorials from creators like Fireship, Josh Tried Coding, and JavaScript Mastery.
What is Aceternity UI?
Aceternity UI is a collection of ready-made interface pieces for React and Next.js projects. Each component arrives styled with Tailwind CSS and animated with Framer Motion, which means a card already tilts on hover and a background already shifts on its own. You do not install a heavy dependency or configure an animation system. You copy the code into your project, adjust a few props, and ship.
The library focuses on motion because that is where most teams lose hours. Writing smooth, accessible animation by hand is slow. Aceternity UI hands you the finished version so you can spend your time on content and layout instead.
Components inside Aceternity UI
The library covers everything from plain buttons to layered 3D effects. With more than 70 components in total, you get buttons, marquees, parallax sections, and grid layouts in one place. The animation-first approach matches what most modern marketing sites and product pages aim for right now.
How to install Aceternity UI components
Setup takes a few minutes. You need a React or Next.js project with Tailwind CSS already configured. Then follow four steps:
- Open the Aceternity UI components page and pick a component.
- Copy the code, or run the Shadcn CLI command listed on the component (for example,
npx shadcn@latest addfollowed by the component path). - Paste it into your components folder and import it where you need it.
- Adjust the props to fit your design. The 3D Card Effect, for instance, exposes values like
translateZso you can control how far elements lift.
Because the components ship as plain React and Tailwind code, you can read and edit every line. Nothing is hidden behind a build step.
What developers build with Aceternity UI
Browse the aceternity-ui topic on GitHub and you will see the same use cases repeat:
- Portfolios: developers use the animations to make personal sites stand out to recruiters and clients.
- SaaS apps: dashboards and landing pages use the motion to hold attention and explain features.
- E-commerce: animated product cards and carousels make storefronts feel more finished.
The range runs from single-page Next.js portfolios to full template repositories you can fork.
Why developers choose Aceternity UI
Feedback across the community is consistent. The main site collects quotes about how fast the components are to drop in. On X, developers such as Teddarific and rh_rahat_dev have pointed to the animations and the simple setup. On Reddit, a member of r/developersIndia shared a portfolio built with the library and got design feedback and bug reports in return, which shows people use it on real projects.
Video tutorials add to the reach. Jeff from Fireship, Josh from Josh Tried Coding, and the JavaScript Mastery channel have all covered it, so you can learn by watching.
Aceternity UI free vs Pro
The core library is free, and most projects can ship on the free tier alone. If you want more, Aceternity UI Pro adds extra component packs, full page templates, and lifetime updates. It targets developers and teams who want ready-made sections rather than building each page from parts.
