An AI agent native stack

ReactVision is the XR development stack for AI agents: the open-source ViroReact renderer, ReactVision Spatial for spatial infrastructure, the MCP server that connects your coding agent to all of it, and the visual Editor. It is built from the ground up for agents to build complete AR and VR applications. We control the whole stack, from renderer to spatial infrastructure, so agents work from one current source of truth, test what they build, and ship once to every device.

Who it's for

Teams shipping spatial apps where it matters, from secure sites to the buyer's own phone.

Defence

AR and VR inside secure environments

Spatial and the MCP run on-prem, ViroCore brings the stack to custom hardware, and nothing leaves your network.

Enterprise

Build once, outlive the device

One codebase across every device, so the next end of life (HoloLens 2 support ends 31 December 2027) doesn't force a rewrite.

HoloLens 2 migration →
Training and simulation

Collaborative MR and VR training

Collaborative mixed reality training on Quest with co-location and replicated state, VR procedures, and environment rendering to review a scene in the real room before going on site.

Real estate and property

Spatial data on every property, for people and robots

VPS scans and hosts a space so you understand it: maintain residential and commercial portfolios, gather location and setting data for robots, and keep content exactly where you put it. Advanced VPS coming soon.

Startups

Build the XR products that define what comes next

Pokémon Go and Snapchat are the starting point, not the ceiling. Anchors, co-location and AI asset generation from a free tier, with no backend to build. Proof: Pikd, used by Red Bull and Burger King.

ReactVision questions, answered

What is ReactVision?
ReactVision is the XR development stack for AI agents. It combines four products from one company: ViroReact, the open-source renderer; ReactVision Spatial, managed spatial infrastructure; the ReactVision Editor, for building visually; and the ReactVision MCP server, which gives coding agents access to the whole stack. Developers and their agents use ReactVision to build AR, VR and mixed reality apps from one React Native codebase.
Which devices and platforms does ReactVision support?
ReactVision apps run on five platforms from one codebase: iPhone and iPad (ARKit), Android (ARCore), Meta Quest 3 and 3S (OpenXR, including passthrough mixed reality), Apple Vision Pro (visionOS), and the web. Android XR support is coming soon.
Is ViroReact free?
Yes. ViroReact is open source under the MIT licence and free forever, with no runtime fees, whatever ReactVision plan you are on. ViroReact had 140k+ installs in 2025. ReactVision Spatial, the Editor and the MCP server start on a free tier, with usage-based paid plans as you grow.
How do AI agents build with ReactVision?
AI coding agents connect to the ReactVision MCP server, which works with Claude, Claude Code, Cursor, Codex, Windsurf and any MCP-compatible agent. Through the ReactVision MCP server an agent reads the live ViroReact APIs and docs, checks platform support per device, generates 3D models and images, and validates and render-tests its scenes, including inside recorded real-world rooms, before anyone opens a device. A free ReactVision account is all it needs to connect.
What is ReactVision Spatial?
ReactVision Spatial is the managed spatial infrastructure behind ReactVision apps: Cloud and Geospatial Anchors, Co-Location, replicated state, AI asset generation, asset hosting with over-the-air updates, and environment rendering. Its Spatial Intelligence features add VPS, on-device object detection, semantic understanding, depth and surface understanding. ReactVision Spatial is built into ViroReact, so there is no backend to build or run.
How much does ReactVision cost?
ReactVision has a free plan with no card required, which includes the ReactVision MCP server, the Editor, ViroReact, 500 MB of asset hosting, 1,000 Spatial API requests and 350 AI credits a month. Paid plans are Basic at $25 a month and Pro at $75 a month, with lower prices on annual billing, and add more hosting, Spatial API requests, AI credits and Environment Testing. Enterprise plans are all custom priced for higher demand, with the option of a dedicated ReactVision Spatial instance for very high-demand projects; contact ReactVision for a quote. ViroReact is free under MIT on every plan.
Can ReactVision run on-premises?
Yes. ReactVision Spatial and Spatial Intelligence can be deployed inside your own secure infrastructure, so data, anchors and assets never leave it, and ViroCore brings ViroReact to custom hardware. On-premises deployments are a fixed licence plus maintenance, and enterprise plans include SSO and audit logging. The managed cloud is usage-based, with a free tier.
