ViroReact, By ReactVision

ViroReact is the most widely used open-source library for building Augmented Reality (AR) and Virtual Reality (VR) experiences with React Native. Write your app once in TypeScript and ship it natively across mobile AR and VR headsets — no new engine, no new language, no months of ramp-up.

ViroReact is MIT licensed and free forever.

Supported Platforms

ViroReact works with both React Native CLI and Expo projects.

Installation

npm install @reactvision/react-viro

For Expo projects, the easiest way to start is to clone the official starter kit:

• Expo + TypeScript starter kit: https://github.com/ReactVision/expo-starter-kit-typescript
• React Native CLI starter kit: https://github.com/ReactVision/starter-kit

For step-by-step setup instructions, including platform-specific permissions and build configuration, see the full installation guide in the docs: https://viro-community.readme.io/docs/installation-instructions

MCP Server

If you're building AR, VR or XR apps with ViroReact, our MCP server is the fastest way to get moving. Think of it as a living guide to ViroReact, always current, that plugs straight into the tools you already use.

Connect it to Claude, Codex, Cursor or any other coding agent, and your agent instantly understands how to work with ViroReact's cross-platform rendering. No hunting through docs, no guesswork. (Our documentation is still a great companion, but the MCP is the most up to date source there is.)

MCP Setup Instructions

Features

ViroReact ships with a complete spatial computing toolkit out of the box — no third-party plugins, no paid add-ons.

Tracking and anchoring

• AR plane detection with horizontal and vertical surface anchors
• Image and object recognition triggers
• Cloud Anchors for persistent, multi-user shared AR content (Platform feature)
• Geospatial Anchors that pin content to real-world latitude, longitude, and altitude (Platform feature)

Rendering

• PBR lighting, HDR environment maps, and real-time shadow casting
• 360° photo and video environments
• Portal rendering for immersive pass-through experiences
• OBJ, FBX, and GLTF/GLB model loading with embedded animations
• Custom procedural geometry and custom GPU shaders

Interaction and motion

• Built-in physics engine with dynamic and static bodies, collision callbacks
• Particle system for fire, smoke, rain, snow, confetti, and other effects
• Declarative animation system with sequencing and chaining
• Full input event system: tap, drag, pinch, rotate, fuse, hover

Audio

• Spatial audio, 360° sound fields, and positioned 3D audio

Platform Features

Cloud Anchors, Geospatial Anchors, and AI-powered 3D asset creation are powered by ReactVision Platform — managed cloud infrastructure built directly into ViroReact. Add your rvApiKey and rvProjectId and the platform handles hosting, resolution, and geospatial infrastructure for you.

You can get a Studio account, which includes Platform access, for free at https://studio.reactvision.xyz.

Studio

ReactVision Studio is our browser-based visual scene editor for AR and VR. Build scenes visually in Studio, then embed them inside your own ViroReact app with a single component. Designers and developers can iterate on a scene in Studio and have it update in production without a new app build.

Build scenes visually

• Placement — drag-and-drop 3D objects, images, video, text, and primitives into a scene with visual gizmos for position, rotation, and scale. No JSX required to lay out a scene.
• AI asset generation — generate 3D models from a text prompt or reference image directly inside the editor, powered by ReactVision Platform.
• Animations — author keyframe and property animations on a timeline, chain them into sequences, and trigger them from interactions or scene events.
• Physics — assign dynamic, static, or kinematic bodies to objects, configure mass, friction, and restitution, and wire up collision callbacks — the same physics engine ViroReact ships with, exposed visually.

Embed Studio scenes in your app

Drop the StudioSceneNavigator component into your ViroReact app, point it at a Studio scene, and your app picks up whatever your team is editing in Studio without a new native build.

A little history…

ViroReact was originally developed by Viro Media and open-sourced in 2019. In late 2020, the Viro Community formed to maintain and modernise the project, keeping it compatible with current React Native versions. In January 2025, Morrow Digital acquired the project to invest in its future, and in late 2025 ReactVision was spun out as an independent company with a full-time team building the next generation of XR tooling.
