A lottie is a high-quality vector animation format based on JSON that can be easily integrated into websites and applications. Originally developed by Airbnb for native mobile apps, this format can be created in Adobe After Effects and then exported as JSON using the Bodymovin extension. An alternative to After Effects is the Lottie Editor. The associated scripts and player can be easily embedded in HTML code. For additional resources on lotties, you can explore the Lottiefiles.com library, consult tutorials on creating lottie animations, or access the dedicated GitHub repository.
