Which should you use? A side-by-side look at what each one does, who it suits, what it costs, how hard it is to set up, and where each falls short.
Open source · MIT
An open source animation library for JavaScript, React and Vue.
Open source · MIT
A small JavaScript library that reports where an element sits during scrolling and fires events as it changes.
The short answer
Choose Motion if you need…
- React developers who want to animate components with a simple API
- JavaScript developers animating elements on a web page
- Vue developers looking for an animation package
- Teams building interactive websites that need gestures, springs or scroll-linked effects
Choose ScrollMagic if you need…
- Web developers adding scroll-triggered effects such as class toggles or lazy loading
- Developers who want scroll-position data without adopting a full animation toolkit
- Projects that need cross-browser scroll tracking with a small footprint
- Teams using React, Vue, or plain JavaScript, since the README says it is framework agnostic

What each one is
Motion
Motion is a code library that lets developers add movement to web pages and apps, such as sliding, fading, springy bounces, and layout changes. It offers packages for React, plain JavaScript and Vue, and its README says it uses browser APIs for smooth, GPU-accelerated animation. It was formerly known as Framer Motion.
ScrollMagic
ScrollMagic tells you where an element is relative to the viewport as the user scrolls, and fires events such as enter, leave, and progress when that changes. It wraps the browser's IntersectionObserver and ResizeObserver APIs and handles some edge cases for you. It does not animate anything by itself; you decide what to do with the scroll data, such as toggling classes or driving animations.
Best for
Motion
- React developers who want to animate components with a simple API
- JavaScript developers animating elements on a web page
- Vue developers looking for an animation package
- Teams building interactive websites that need gestures, springs or scroll-linked effects
ScrollMagic
- Web developers adding scroll-triggered effects such as class toggles or lazy loading
- Developers who want scroll-position data without adopting a full animation toolkit
- Projects that need cross-browser scroll tracking with a small footprint
- Teams using React, Vue, or plain JavaScript, since the README says it is framework agnostic
Strengths
Motion
- The README lists first-class React, JavaScript and Vue packages under one name
- Released under the MIT license and tree-shakable, per the README
- Large official example library with 450+ examples and tutorials
ScrollMagic
- Zero dependencies and a small bundle, according to the README badges
- Works with any scroll container, including window or a custom element, and supports horizontal and vertical scrolling
- MIT licensed and free to use
Not ideal for
Motion
- People who want a visual tool with no coding: the README's visual editor, Motion Studio, is a separate product
- Projects that need only a few CSS transitions, where native CSS may be simpler (general judgment, not stated in the README)
ScrollMagic
- People who want a ready-made animation solution: the README itself points to GSAP ScrollTrigger, Motion, or anime.js for that
- Users who only need simple CSS scroll effects, since native scroll-driven animations may cover those without a library (the README notes limited browser support)
- Non-programmers, because it is used through JavaScript code
Trade-offs
Motion
- Some advanced features, including Motion+ content and the Transition editor, are paid
- The README does not describe bundle size or performance numbers beyond general claims
- Formerly Framer Motion; older projects need their imports updated to motion/react
ScrollMagic
- Provides data and events only; you must write the animation or behavior yourself
- The README describes this as version 3 with a v2 legacy branch, and the install command uses the next tag, so the API may still be settling
- Native scroll-driven animations are not yet supported in all browsers, which the README acknowledges for the alternative path
