The simplest way to add scroll animations to a website. Great for marketing sites and portfolios. For more control over scroll animations, consider GSAP ScrollTrigger instead.
5. Lottie
React, Vue, Angular, Vanilla JS
Render After Effects animations natively on web, iOS, and Android. Designers create animations in After Effects, export as JSON via Bodymovin plugin, and developers render them pixel-perfectly.
Key Features:
- After Effects to web pipeline

Frequently Asked Questions
CSS animations use keyframes and transitions defined in stylesheets, running on the browser's compositor thread for better performance with simple animations. JavaScript animations (like GSAP or Framer Motion) offer more control, can animate any property, support complex sequencing, and can respond to user interactions. For simple hover effects and transitions, use CSS. For complex, interactive, or sequenced animations, JavaScript libraries are better.
Yes, GSAP core is completely free for commercial use, including CSSPlugin, AttrPlugin, and more. However, some premium plugins (MorphSVG, DrawSVG, SplitText, ScrollSmoother, etc.) require a paid license for commercial projects. These premium plugins are free to use on CodePen and for personal projects. The 'Business Green' license starts at $199/year.
Framer Motion is generally considered the best choice for React applications due to its declarative API, excellent documentation, and seamless React integration. However, React Spring is excellent for physics-based animations, and GSAP remains the choice for complex, high-performance needs. For simple animations, AutoAnimate adds polish with minimal code.
For simple scroll animations, AOS (Animate On Scroll) is the easiest solution - just add data attributes to elements. For more control, GSAP's ScrollTrigger plugin is the industry standard, offering pinning, scrubbing, and complex sequences. Framer Motion and Motion One also have built-in scroll animation support. Native CSS now supports scroll-driven animations with the animation-timeline property, though browser support varies.
Choose Framer Motion for most React projects - it has a gentler learning curve, excellent documentation, and handles common animations beautifully with its declarative API. Choose React Spring when you need spring-physics based motion, complex gesture interactions, or React Native support. Both are excellent; Framer Motion is more approachable while React Spring offers more granular control over spring physics.
