An open-source CSS animation library with a live preview grid, creator suite, and community submissions

JavaScript animation libraries are heavy. GSAP, Framer Motion, anime.js - all runtime weight

for something CSS can handle natively, faster, and on the GPU.

So I built CSSFrames. A curated motion preset library built entirely on pure CSS keyframes.

Browse, preview, export, and ship — no JS runtime, no layout thrashing, no dropped frames.
