Rive

Rive is a platform for creating vector-based, real-time animations intended for integration into software projects such as mobile apps, websites, and games. It combines a design editor with a runtime, enabling designers and developers to build interactive, state-driven animations without hand-coding every interaction.

Rive's editor provides vector drawing tools for shapes, path-based drawing, gradients, masks, and asset organization. Central to Rive is a state-driven workflow, where animations can respond to user input or application state using a state machine, triggers, booleans, and numeric values. Animations are exported as binary assets (.riv) that are consumed by runtime libraries on target platforms.

Rive supports cross-platform inclusion via official runtimes and SDKs, allowing the same animation data to play on iOS, Android, the web, and other targets. It enables designers to create reusable assets with components and constraints, and to prototype interactions at scale. The web-based editor at rive.app is commonly used to author and iterate on animations, which can then be integrated into apps via the runtimes and APIs provided by Rive.

Rive is used to implement UI micro-interactions, onboarding flows, animated illustrations, and gameplay UI. It is developed by Rive, Inc., and has been adopted by developers and designers seeking an efficient, scalable animation pipeline within product development.
