Choose Rive when behavior matters
Rive is designed for interactive graphics. A single file can contain idle, hover, loading, success, error, talking, and celebration states, with transitions controlled by product data or user actions.
Typical uses include app mascots, AI assistants, onboarding guides, game UI, interactive buttons, and dashboards with animated feedback.
Choose Lottie for a linear sequence
Lottie is a practical choice for exported motion that plays from start to finish, loops, or is controlled mainly by playback progress. It is often suitable for decorative illustrations, logo reveals, and simple loading sequences.
If the animation does not need state logic, a state machine may add unnecessary production scope.
Consider the developer workflow
Ask who owns the states, controls, layout, and updates after launch. Rive can move more interaction logic into the animation file. Lottie usually leaves product logic in application code while the visual asset remains linear.
