## What it is
GSAP (GreenSock Animation Platform) is a framework-agnostic JavaScript animation library for animating CSS, SVG, canvas, WebGL, and generic objects with high performance across all major browsers. It includes a plugin ecosystem such as ScrollTrigger, SplitText, MorphSVG, and Flip, and is now entirely free thanks to Webflow's support.

## Use cases
- animate dom elements with javascript
- create scroll-based animations on a website
- animate svg path drawing and morphing
- build smooth animation sequences and timelines in react
- add parallax and smooth scrolling effects
- animate text splitting and scramble effects
- create flip layout transitions

## When to choose
- you need high-performance, cross-browser animations with zero dependencies
- you want advanced sequencing, easing, and scroll-driven effects with minimal code
- you need framework-agnostic animation that works with React, Vue, Webflow, or plain JS
- you want a mature, battle-tested library used on millions of production sites

## When to avoid
- you only need simple CSS transitions or keyframe animations without JS
- you require an OSI-approved open-source license for strict compliance policies
- you want a declarative, CSS-only animation approach
- your project is non-web (native mobile/desktop) where web animation libraries don't apply

## Facets
- artifact type: library
- maturity: stable
- function: animation, ui-components, frontend-framework
- domain: web-development, frontend, graphics, web-design
- platform: browser, cross-platform
