Rive is a real-time interactive animation design platform that integrates an interactive editor, open-source runtime, and high-performance renderer. It aims to streamline collaboration between designers and developers. Through its core State Machine system, users can create responsive animations and deploy them to apps, games, and websites with one click. Rive uses vector graphics technology to ensure animations run smoothly at 120fps on any device, with file sizes only 1/10 of traditional formats.
Core Features
State Machine-Driven Interactivity
- Visual state machine editor supporting animation state transitions triggered by user inputs (clicks, hovers).
- Supports transition conditions, event listeners, and data binding for complex interaction logic.
Professional Animation Tools
- Timeline animation: Keyframe editing, easing curve adjustment, and animation blending.
- Skeleton system: Inverse Kinematics (IK), skin weighting, and character animation support.
- Vector graphics: Pen tool, shape boolean operations, gradient fills, and vector feathering.
Cross-Platform Runtime
- Open-source runtime libraries (MIT License) supporting 20+ platforms including Web/JS, iOS, Android, Flutter, Unity, and Unreal.
- Lightweight renderer: Optimized vector drawing technology with low memory usage.
Collaboration & Workflow
- Real-time multi-user editing, version history tracking, and team permission management.
- Supports Figma and Sketch imports, exporting to Rive format (.riv) or video (WebM/MP4).
Features & Advantages
| Feature | Description |
|---|---|
| Dynamic Interactivity | State Machine system enables animations to respond to user behavior, replacing traditional linear animations. |
| Performance Optimization | Vector graphics result in smaller file sizes, 10x faster loading than GIFs, and smooth operation on low-end devices. |
| Cross-Platform Consistency | Single animation asset seamlessly adapts to mobile, web, and game engines, eliminating redundant development. |
| Open-Source Ecosystem | Open-source runtime and format with active community support, allowing custom extensions. |
| Real-Time Feedback | Instant animation preview in the editor shortens design-development iteration cycles. |
