Lottie presents a promising concept of an open format for animated vector graphics, allowing animations to be created from what animators use. However, the transition to real-world application has faced significant challenges. Users express frustration with its performance, particularly regarding JSON's overhead compared to a binary format, which could provide smoother and more compact implementations. The Lottie library tends to inflate web bundle sizes significantly due to its resource requirements, risking performance issues on lower-end devices when multiple animations play simultaneously. Alternatives like CSS and SVG animations seem more favorable for web development, especially as they often result in a smaller footprint and better optimization. Feedback also highlights a learning curve with Lottie compared to these traditional methods. Over time, while Lottie may suit mobile applications, its deployment on web platforms can create burdensome experiences for developers and users alike.
