    GSAP (GreenSock Animation Platform)

    Professional-grade animation for the modern web

    GSAP is a JavaScript library for building 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! The ScrollTrigger plugin lets you create jaw-dropping scroll-based animations with minimal code. No other library delivers such advanced sequencing, reliability, and tight control while solving real-world problems on millions of 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! See for what makes GSAP so special.

    What is GSAP?

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

    There are many optional plugins and easing functions for achieving advanced effects easily like morphing, scrolling, or animating along a motion path.

    Click the green "Get GSAP Now" button at for more options and installation instructions, including CDN URLs for various plugins.

    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).


    See the guide to using GSAP via NPM here.

    npm install gsap

    The default (main) file is gsap.js which includes most of the eases as well as the core plugins like CSSPlugin, AttrPlugin, SnapPlugin, ModifiersPlugin, and all of the utility methods like interpolate(), mapRange(), etc.

    // typical import
    import gsap from "gsap";
    // or get other plugins:
    import Draggable from "gsap/Draggable";
    import ScrollTrigger from "gsap/ScrollTrigger";
    // or all tools are exported from the "all" file (excluding bonus plugins):
    import { gsap, ScrollTrigger, Draggable, MotionPathPlugin } from "gsap/all";
    // don't forget to register plugins
    gsap.registerPlugin(ScrollTrigger, Draggable, MotionPathPlugin);

    The NPM files are ES modules, but there's also a /dist/ directory with UMD files for extra compatibility.

    Download Club GreenSock members-only plugins from your account and then include them in your own JS payload. There's even a tarball file you can install with NPM/Yarn. Post questions in our forums and we'd be happy to help.
