  • Animated marketing sections: heroes, feature grids, testimonials and backgrounds with motion built in.
  • Volume for landing pages: 200+ premium blocks, 15+ templates and 4 full pages in the paid plans.
  • A Team plan for up to 10 people.
  • Works with Claude Code, Codex and Cursor through the shadcn MCP server and its registry.

What PixilUI adds

  • A 14-day refund before any Pro source is installed.

Using both

Use Aceternity UI on the marketing pages and PixilUI in the app. They rarely meet on one screen, so their styling never has to agree.

Questions

Aceternity UI or PixilUI for an AI product?

Both, for different pages. Aceternity UI for the marketing site and launch page, PixilUI inside the product where the agent asks for approval, runs steps, calls tools and streams text.

Can I use both in commercial projects?

Yes. Aceternity UI's site says its components can be used in unlimited personal and commercial client projects, without reselling them as a competing library. PixilUI's free items are MIT, and Pro items are licensed for your products and client work.
