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.
PlayCanvasWeb 3D apps and games on the PlayCanvas engine, edited in the cloud editor or as code.
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.
PlayCanvasNo model included. An Editor MCP server and skills let Cursor, Claude Code or Codex create entities, assets and scripts.
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.
PlayCanvasThe editor and projects on playcanvas.com; engine-only projects 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.
PlayCanvasLaunch from the editor; 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.
PlayCanvasMeta Quest VR and AR; Apple Vision Pro VR sessions; Android phones; desktop with SteamVR. iOS AR needs a third-party library.
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.

  • First-class Gaussian splats (SuperSplat) and a deep AR feature set.
  • MIT engine and free self-hosting.

Where Graspable is

  • An agent that builds, checks and repairs the project for you.
  • An emulated Quest 3 or Meta VR Glasses with replayed sessions as tests.
  • React Three Fiber, which many developers already know; the code on your disk.

Our take

PlayCanvas is a mature engine with a fine editor; Graspable is an agent that does the building and checking. If you would rather describe than drag, and want the project in your own folder, Graspable is the better fit.
