A library for iOS and Android from the developers at Airbnb that parses Adobe After Effects animations and renders the vector animations natively on mobile. Lottie can handle animations exported as JSON using the bodymovin plugin and as the animations are backed by JSON they can be complex without being huge in size. Best of all, as the animations are rendered as vectors they can be resized, looped, sped up, slowed down, and even interactively scrubbed without any loss in quality.
