# GSAP (GreenSock Animation Platform)
[](http://gsap.com)
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, [text splitting](https://gsap.com/docs/v3/Plugins/SplitText), animating along a motion path or FLIP animations. There's even a handy Observer for normalizing event detection across browsers/devices.
### Get Started

## Docs & Installation
View the full documentation here, including an installation guide.
### CDN
```html
```
See JSDelivr's dedicated GSAP page for quick CDN links to the core files/plugins. There are more installation instructions at gsap.com.
**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 guide to using GSAP via NPM here.
```javascript
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.
```javascript
// 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.
## GSAP is FREE!
Thanks to [Webflow](https://webflow.com), GSAP is now **100% FREE** including ALL of the bonus plugins like [SplitText](https://gsap.com/docs/v3/Plugins/SplitText), [MorphSVG](https://gsap.com/docs/v3/Plugins/MorphSVGPlugin), 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](https://webflow.com/blog/gsap-becomes-free)
### ScrollTrigger & ScrollSmoother
If you're looking for scroll-driven animations, GSAP's ScrollTrigger plugin is the standard. There's a companion ScrollSmoother as well.

### Using React?
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.
