Lottie
A cross-platform library for iOS, macOS, tvOS, and visionOS that natively renders After Effects animations from JSON.
What is Lottie?
Lottie is an iOS library that natively renders vector-based animations exported from After Effects in the bodymovin JSON format. It solves the problem of engineers painstakingly recreating complex animations by hand, allowing designers to directly ship their work. The library enables real-time playback with full control over animation properties like speed, looping, and runtime modifications.
iOS, macOS, tvOS, and visionOS developers who need to integrate high-quality, designer-created animations into their applications efficiently.
Developers choose Lottie because it drastically reduces the engineering effort required to implement complex animations, ensures pixel-perfect fidelity to the original design, and provides extensive runtime control. Its JSON-based approach results in small file sizes and seamless integration across Apple platforms.
