GSAP (GreenSock Animation Platform)

GSAP is a framework-agnostic JavaScript animation library that turns developers into animation superheroes. Build high-performance animations that work in every major browser. Animate CSS, SVG, canvas, React, Vue, WebGL, colors, strings, motion paths, generic objects... anything JavaScript can touch! GSAP's <a href="https://gsap.com/docs/v3/Plugins/ScrollTrigger/">ScrollTrigger</a> plugin delivers jaw-dropping scroll-based animations with minimal code. <a href="https://gsap.com/docs/v3/GSAP/gsap.matchMedia()">gsap.matchMedia()</a> makes building responsive, accessibility-friendly animations a breeze.

No other library delivers such advanced sequencing, reliability, and tight control while solving real-world problems on over 12 million sites. GSAP works around countless browser inconsistencies; your animations just work. At its core, GSAP is a high-speed property manipulator, updating values over time with extreme accuracy. It's up to 20x faster than jQuery!

GSAP is completely flexible; sprinkle it wherever you want. Zero dependencies.

There are many optional <a href="https://gsap.com/docs/v3/Plugins">plugins</a> and <a href="https://gsap.com/docs/v3/Eases">easing</a> functions for achieving advanced effects easily like <a href="https://gsap.com/docs/v3/Plugins/ScrollTrigger/">scrolling</a>, <a href="https://gsap.com/docs/v3/Plugins/MorphSVGPlugin">morphing</a>, text splitting, animating along a <a href="https://gsap.com/docs/v3/Plugins/MotionPathPlugin">motion path</a> or <a href="https://gsap.com/docs/v3/Plugins/Flip/">FLIP</a> animations. There's even a handy <a href="https://gsap.com/docs/v3/Plugins/Observer/">Observer</a> for normalizing event detection across browsers/devices.

Every major ad network excludes GSAP from file size calculations and most have it on their own CDNs, so contact them for the appropriate URL(s).

NPM

See the <a href="https://gsap.com/install">guide to using GSAP via NPM here</a>.

npm install gsap

GSAP's core can animate almost anything including CSS and attributes, plus it includes all of the <a href="https://gsap.com/docs/v3/GSAP/UtilityMethods">utility methods</a> like <a href="https://gsap.com/docs/v3/GSAP/UtilityMethods/interpolate()">interpolate()</a>, <a href="https://gsap.com/docs/v3/GSAP/UtilityMethods/mapRange()">mapRange()</a>, most of the <a href="https://gsap.com/docs/v3/Eases">eases</a>, and it can do snapping and modifiers.

// typical import
import gsap from "gsap";

// get other plugins:
import ScrollTrigger from "gsap/ScrollTrigger";
import Flip from "gsap/Flip";
import Draggable from "gsap/Draggable";

// or all tools are exported from the "all" file (excluding members-only plugins):
import { gsap, ScrollTrigger, Draggable, MotionPathPlugin } from "gsap/all";

// don't forget to register plugins
gsap.registerPlugin(ScrollTrigger, Draggable, Flip, MotionPathPlugin);

The NPM files are ES modules, but there's also a /dist/ directory with <a href="https://www.davidbcalhoun.com/2014/what-is-amd-commonjs-and-umd/">UMD</a> files for extra compatibility.

GSAP is FREE!

Thanks to Webflow, GSAP is now 100% FREE including ALL of the bonus plugins like SplitText, MorphSVG, and all the others that were exclusively available to Club GSAP members. That's right - the entire GSAP toolset is FREE, even for commercial use! 🤯 Read more here

ScrollTrigger & ScrollSmoother

If you're looking for scroll-driven animations, GSAP's <a href="https://gsap.com/docs/v3/Plugins/ScrollTrigger/">ScrollTrigger</a> plugin is the standard. There's a companion <a href="https://gsap.com/docs/v3/Plugins/ScrollSmoother/">ScrollSmoother</a> as well.

Using React?

There's a <a href="https://www.npmjs.com/package/@gsap/react">@gsap/react</a> package that exposes a useGSAP() hook which is a drop-in replacement for useEffect()/useLayoutEffect(), automating cleanup tasks. Please read the <a href="https://gsap.com/react">React guide</a> for details.
