Graspable vs Needle Engine

Needle starts from an artist’s Unity or Blender scene; Graspable starts from a sentence. Both end on the web and on headsets.

Needle Engine ships 3D to the web from Unity or Blender: the integrations export glTF and a web project on a three.js-based runtime, with hosting on Needle Cloud and an MCP server for agents. Facts about Needle Engine are from its own pages, listed at the end, last checked on 3 October 2026. If something is out of date, tell us.

Choose Graspable when

you have no scene yet and want an agent to build and check one, or you want React Three Fiber code of your own.

Choose Needle Engine when

you already have scenes in Unity or Blender with lighting, animation and physics, and want them on the web and in headsets with an artist-first pipeline.

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.
Needle EngineWeb apps exported from Unity or Blender (or written in code) on Needle’s three.js-based runtime; static output you can host anywhere.
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.
Needle EngineNo model included; a Needle MCP server and an agent skill for Claude Code, Cursor, Copilot, Codex and Gemini CLI; metered AI assistant usage on Needle Cloud.
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.
Needle EngineLocally in Unity or Blender plus a local web project; deploy to Needle Cloud, Netlify, Vercel, GitHub Pages and others.
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.
Needle EngineLocal preview on devices; no build gate or emulated-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.
Needle EngineQuest 1 to 3S with hands, passthrough and depth; Apple Vision Pro VR; Pico, Index, Vive, HoloLens 2; Android phones; iOS through an App Clip and interactive USDZ.
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.
Needle EngineStatic builds you own; the runtime is proprietary. Hobby output carries Needle branding.
Price
GraspableFree to build with on your computer, on every plan. Builder $20, Pro $40, Studio $99 per seat add Cloud Agents, Fast mode, premium templates, teams and Credits (graspable.dev/pricing).
Needle EngineHobby free for non-commercial use; Pro €49 per seat a month billed yearly for commercial use; Enterprise custom (cloud.needle.tools/pricing).
Native headset apps
GraspableWeb only today: no Unity, Unreal or native headset builds.
Needle EngineNone; web, plus an iOS App Clip.

Where Needle Engine is the better choice

  • An artist pipeline from Unity or Blender with lightmaps, animation and physics.
  • The broadest documented device list, including iOS AR through an App Clip.
  • Multiplayer and voice built in.

Where Graspable is

  • No Unity or Blender needed: a sentence, an agent, a checked project.
  • Your own AI account; free for commercial use on your computer.
  • React Three Fiber code of your own, and publishing from the app.

Our take

Needle is the better route for an artist with a finished Unity or Blender scene. Starting from nothing, with an agent that builds and checks, Graspable is the shorter road to a headset.

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.
