What is Lottie?

Lottie is a JSON-based animation format that lets you ship lightweight, scalable animations on any platform.

Think of it as animated SVGs. The animations are vector-based, so they scale to any size without pixelation, and the file sizes are tiny compared to GIFs or MP4s.

Most builders use Lottie for loading indicators, onboarding flows, empty states, and micro-interactions in apps and websites. You can create them in After Effects with the Bodymovin plugin or use tools like LottieFiles to browse thousands of free animations.

Open source format created by Airbnb. Free to use. Works on iOS, Android, web, and React Native with official libraries for each platform.
