GSAP (GreenSock Animation Platform) is a powerful JavaScript library for creating high-performance animations that work in all major browsers. It is widely used for animating web elements, SVGs, and more, providing a rich set of features for developers to create complex animations with ease.
Basic Tweening
This feature allows you to animate any property of an element over a specified duration. In this example, the element with the class 'element' will move 100 pixels to the right over 1 second.
gsap.to('.element', { duration: 1, x: 100 });Timeline Animations
Timelines allow you to sequence multiple animations. In this example, 'element1' will move 100 pixels to the right, and then 'element2' will move 100 pixels down, each over 1 second.
const tl = gsap.timeline();
tl.to('.element1', { duration: 1, x: 100 })
.to('.element2', { duration: 1, y: 100 });Stagger Animations
Staggering allows you to animate multiple elements with a delay between each start. In this example, each element with the class 'elements' will move 100 pixels to the right, starting 0.2 seconds after the previous one.
gsap.to('.elements', { duration: 1, x: 100, stagger: 0.2 });ScrollTrigger
ScrollTrigger allows you to create animations that are triggered by scrolling. In this example, the element with the class 'element' will move 100 pixels to the right when it enters the viewport.
gsap.registerPlugin(ScrollTrigger);
gsap.to('.element', { scrollTrigger: '.element', x: 100 });Anime.js is a lightweight JavaScript animation library with a simple, yet powerful API. It supports CSS properties, SVG, DOM attributes, and JavaScript Objects. Compared to GSAP, Anime.js is more lightweight but may lack some of the advanced features and plugins that GSAP offers.
Velocity is an animation engine with the same API as jQuery's $.animate(). It works with and without jQuery. Velocity is known for its performance and ease of use, but it doesn't offer as many features and plugins as GSAP.
Popmotion is a functional, flexible JavaScript animation library. It provides a range of tools for creating animations and interactions. While it is highly modular and flexible, it may require more setup and understanding compared to GSAP's more straightforward API.
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 ScrollTrigger plugin delivers jaw-dropping scroll-based animations with minimal code. gsap.matchMedia() 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 plugins and easing functions for achieving advanced effects easily like scrolling, morphing, animating along a motion path or FLIP animations. There's even a handy Observer 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).
See the guide to using GSAP via NPM here.
npm install gsap
GSAP's core can animate almost anything including CSS and attributes, plus it includes all of the utility methods like interpolate(), mapRange(), most of the eases, 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 UMD files for extra compatibility.
Download Club GSAP members-only plugins from your gsap.com account and then include them in your own JS payload. There's even a tarball file you can install with NPM/Yarn. GSAP has a private NPM registry for members too. Post questions in our forums and we'd be happy to help.
If you're looking for scroll-driven animations, GSAP's ScrollTrigger plugin is the new standard. There's a companion ScrollSmoother as well.
There's a @gsap/react package that exposes a useGSAP() hook which is a drop-in replacement for useEffect()/useLayoutEffect(), automating cleanup tasks. Please read the React guide for details.
