Motion (Animation Library)

Motion, formerly known as Framer Motion, is a robust and highly performant open-source animation library designed for modern web development, offering first-class support for React, vanilla JavaScript, and Vue (via the separate `motion-v` package). As of version 12.38.0, it provides a simple yet powerful API for creating 120fps, GPU-accelerated animations using a hybrid engine that intelligently combines JavaScript capabilities with native browser APIs. The library maintains an active and frequent release cadence, with updates often published weekly or bi-weekly. Key differentiators include its comprehensive suite of "batteries-included" features, such as declarative gestures (drag, tap, hover), spring physics, advanced layout transitions for shared elements, scroll-linked effects, and complex timeline orchestrations. Motion is production-ready, featuring TypeScript support, tree-shakability, a tiny footprint, and an extensive test suite, making it a reliable choice for building fluid and interactive user interfaces across various platforms.
