Side by side

What you build
GraspableA desktop app for macOS (Windows and Linux are coming). You describe a 3D or XR scene; an AI agent builds it as a real React Three Fiber and WebXR project in a folder on your computer.
Wonderland EngineWebXR apps on Wonderland’s runtime (TypeScript components, WebGPU since 1.5), from a desktop editor on Windows, macOS and Linux.
The AI
GraspableYour own AI account: an API key from Anthropic, OpenAI, OpenRouter and others, a ChatGPT subscription, or Claude Code with a Claude subscription. Models come from the provider’s own list.
Wonderland EngineNo model included. An official MCP server plugin for Cursor, Claude Code, Codex and others; Wonderland notes that language models know the engine poorly.
Where it runs
GraspableOn your computer. Projects, previews, builds, keys and sign-ins stay there. A paid plan can move a project to a Cloud Agent and back.
Wonderland EngineLocally; static web output you host anywhere.
Checking the result
GraspableA run ends only when the project builds and loads in a real browser without errors; recorded headset sessions are replayed after every change.
Wonderland EngineInstant reload in a browser, phone or headset; no build gate or headset replay in the product.
Headsets and devices
GraspableAny browser with WebXR. The app emulates a Meta Quest 3 or Meta VR Glasses in the preview; a project opens on a Quest or an Apple Vision Pro over Wi-Fi or USB.
Wonderland EngineAny headset with a browser: Quest, Vision Pro, Pico, HoloLens, Magic Leap and others listed; phone AR through Zappar-based templates.
Your code
GraspableOrdinary code on your disk: React, three.js, React Three Fiber, @react-three/xr. Yours, in any editor, with a version per run.
Wonderland EngineLocal project; the runtime ships only inside your product, with a required credit line.

Where Wonderland Engine is the better choice

  • Rendering performance beyond a typical React Three Fiber scene.
  • A visual editor and the widest documented headset list.
  • Free until $120,000 a year.

Where Graspable is

  • An agent that builds, checks and repairs, with your own AI account.
  • A plain web stack (React, three.js) that models and developers already know.
  • Emulated headsets and replayed sessions without setup; publishing from the app.

Our take

Wonderland wins on raw performance. Graspable wins on getting a working, checked scene from a sentence in a stack most developers and models already know, and on publishing it from the app.

Graspable is our product. The facts above are what we found; this paragraph is what we think.

Try Graspable

It is a desktop app, free with your own AI account. Describe a scene, watch it being built as a real project on your computer, and open it on your headset. See what people made and the requests behind each.
