Motion is a modern animation library for the web that allows developers to create smooth, interactive animations using React, JavaScript, and Vue. It evolved from Framer Motion and Motion One, combining their capabilities into a unified, production-ready animation system.

The library is designed to simplify complex animation workflows by providing a declarative API that integrates naturally with UI frameworks like React. Developers can animate HTML, SVG, and other values using simple props and hooks, while Motion handles transitions, timing, and performance optimizations behind the scenes.

Motion uses a hybrid animation engine that leverages native browser APIs such as the Web Animations API and ScrollTimeline for high-performance rendering, while falling back to JavaScript when advanced features like spring physics or gesture handling are required. This enables smooth, hardware-accelerated animations that can reach up to 120fps.

It supports a wide range of animation types, including gesture-based interactions (hover, tap, drag), scroll-triggered and scroll-linked animations, layout transitions, and exit animations. These capabilities make it suitable for both simple UI enhancements and complex interactive experiences.

Motion is built with TypeScript, fully tree-shakable, and designed for scalability—from small micro-interactions to large, animation-heavy applications. It also includes tooling like Motion Studio for visual editing and AI-assisted animation workflows.

Key features include:

• Declarative animation API for React, JavaScript, and Vue
• Hybrid engine using native browser APIs and JavaScript fallbacks
• Support for gestures (hover, tap, drag) and scroll-based animations
• Layout and shared element transitions
• High-performance animations with hardware acceleration
• TypeScript support and tree-shakable architecture

Common use cases include:

• Building animated user interfaces
• Creating interactive web experiences
• Implementing micro-interactions
• Designing scroll-based storytelling pages
• Enhancing UX with smooth transitions and gestures

Motion is developed by the team behind Framer Motion, led by Matt Perry, and maintained as an open-source animation library with optional premium tooling (Motion+).
