GSAP

Why we included this project

GSAP has been around long enough that most front-end teams have run into it, and there's a reason it keeps showing up: it is a framework-agnostic animation library with zero dependencies that can animate almost anything JavaScript can touch, from CSS and SVG to canvas and WebGL. Where it earns its keep in everyday work is the plugin ecosystem, especially ScrollTrigger for scroll-based storytelling and SplitText for typography, the kinds of motion that come up constantly on real sites. It smooths over browser inconsistencies so your animations just work, and the tween and timeline model gives you tight control over sequencing without wrapping everything in a declarative framework. If you want a site that feels alive without fighting your existing stack, this is a hard library to beat.
