SmoothUI
130 animated React components including 33 text effects and 16 shader transitions
SmoothUI is a shadcn-compatible registry of 130 animated components built on React 19, Tailwind v4, Motion, and GSAP. Its depth is unusual for a one-maintainer project: 33 text-animation components, 16 WebGL/shader page transitions, 19 AI chat and agent components, and a long tail of showpieces like Dynamic Island, Siri Orb, Number Flow, and a GitHub contribution graph. Everything in the free tier is MIT and installs through the shadcn CLI. For developers building a marketing site or an AI product surface who want polish without wiring GSAP themselves.
npx shadcn@latest add @smoothui/dynamic-islandUse SmoothUI as an overlay on an existing shadcn/ui project, not as its base — it assumes Tailwind v4 and React 19, and it installs under the @smoothui namespace so it will not collide with your shadcn primitives. Its real differentiators are the 33 text-animation components and the 16 shader transitions; when a brief asks for a hero headline reveal or a page wipe, look here before you write GSAP. Watch the payload: the shader transitions ship WebGL and GSAP, so scope them to one hero rather than the whole route tree, and audit the flashier components for reduced-motion and focus handling before shipping to an accessibility-sensitive product.
Why it is here. The deepest free catalog of text-animation and shader-transition components in the shadcn ecosystem, and it shipped commits the day it was catalogued.
- 33 dedicated text-animation components
- 16 WebGL shader page transitions
- 19 AI chat and agent components including Siri Orb
- Tailwind v4 and React 19 from the start
