FLUX UI – Physics-driven motion primitives for React

Summary: FLUX UI provides 40 composable motion primitives powered by a unified physics engine with 7 spring presets, built on React 19, Tailwind CSS v4, and Framer Motion. It offers gesture composition, scroll-linked animations, ambient backgrounds, and AI interaction patterns with a three-tier accessibility system.

What it does

FLUX UI delivers reusable motion primitives that apply physics-based animation behaviors without visual styling, allowing developers to add consistent, coherent motion to React components using simple physics presets.

Who it's for

It targets React developers seeking a standardized, accessible approach to implementing complex motion patterns like entrance reveals, magnetic cursors, and scroll-linked animations.

Why it matters

It solves repetitive animation setup by providing a unified, composable system that ensures consistent physics and accessibility across projects without locking in visual design.
