Rive is a 2D and 3D engine for games, apps, websites, and interactive UI. You can build by hand in the Rive Editor, or let a coding agent like Claude Code, Codex, or Cursor build Rive files through the Rive CLI. State machines, data binding, and scripting turn animations into graphics that react to input. Open-source MIT runtimes cover web, mobile, desktop, game engines, and consoles, with no royalties or runtime fees. It suits designers, developers, and game teams.

• Rive Editor: Draw, rig, animate, and wire up interactive graphics in one place. Pen and Brush tools, bones, meshes, Auto Trace, and Auto Weights handle character rigging.
• State Machine and Data Binding: Connect animations as states, respond to hovers, clicks, taps, and gamepad input, and drive visuals with live data. Your graphics react instead of just playing back.
• Rive CLI for Coding Agents: Agents build Rive files from plain-text Rive Markup Language. The CLI compiles scenes, renders frames headless, and runs in CI, and projects work with Git or Perforce as readable diffs.
• Built-in AI Agent: The Editor's AI Agent writes scripts, builds layouts, and animates. It can also rebuild a Figma file as an interactive Rive app.
• AnimaScript Scripting: Add logic, procedural motion, and custom drawing. Scripts compile to WebAssembly, run sandboxed, and are signed on publish, so runtimes refuse altered scripts.
• Responsive Layouts and UI Tools: Build reflowing layouts, virtualized scrolling lists, N-Slicing, reusable components, and shared libraries for production UI.
• GPU Canvas and 3D: Combine 3D models, cameras, lights, and shaders with vector art. Vector Feathering adds soft edges and glows without the cost of traditional blur.
• Open-Source Runtimes Everywhere: Ship to JavaScript, React, React Native, iOS, Android, Flutter, Unity, Unreal, C++, desktop, PS5, Xbox, and Switch. Plugins also cover Framer, Webflow, and Wix Studio.

• No Runtime Fees: Runtimes are MIT-licensed, with no royalties or revenue share, so shipping to millions of users doesn't raise your costs.
• Interactivity Built In: State machines, listeners, and data binding let you build interactive animations rather than fixed playback files.
• Lightweight Output: The .riv format produces small files, and reviewers point to compact final files compared with JSON-based animation formats.
• Designer-to-Developer Handoff: Reviewers note that motion designers can get animations into products with less developer help, and inputs act as a clear contract between design and code.
• Broad Platform Reach: One file can run across web, mobile, desktop, game engines, consoles, and embedded screens.
• Proven in Production: Spotify, Duolingo, Disney, Riot Games, LinkedIn, and Figma use Rive.

• Seat Caps on Lower Tiers: Cadet tops out at 3 seats and Voyager at 25. Libraries and embed URL hosting start at Voyager, so growing teams move up tiers quickly.
• Enterprise Required for Larger Companies: Organizations with $10M+ in annual revenue go on the Enterprise plan at $120 per seat per month, which costs much more than the self-serve tiers.
• Some AI and Scripting Features in Early Access: The features page lists the AI Agent and scripting as early access. Agent usage runs on monthly credits, and advanced models are limited to Voyager and above.
• Proprietary File Format: The .riv format belongs to Rive. Lottie is an open standard with a larger existing ecosystem, which matters if you want vendor-neutral assets.

• Interactive App UI: Build animated buttons, onboarding flows, and stateful icons for iOS, Android, and desktop. Your designers define the states, and your developers trigger them through inputs.
• Games and Game UI: Create whole 2D or 3D games, or just menus and HUDs, and ship them through Unity, Unreal, C++, or straight to consoles. Gamepad listeners and audio events are built in.
• Website Heroes and Product Stories: Add interactive hero sections and scroll-driven product pages to sites built in React, Framer, Webflow, or Wix Studio, without heavy video files.
• Reactive Characters and Mascots: Rig characters with bones, meshes, and IK, then let them react to user actions. This works for app mascots or AI assistant characters in a product.
• Agent-Driven Production: Have a coding agent generate Rive files from plain text with the CLI, review changes as Git diffs, and verify renders headless in CI before you publish.
• Broadcast, Automotive, and Embedded Graphics: Drive scorebugs and live data overlays, or build vehicle clusters and infotainment screens, using data binding on custom hardware.
