Frequently asked questions
What is Needle Engine?
Needle Engine is a web-first realtime engine built on three.js that lets you create interactive 3D and XR experiences using standard web technologies. It integrates with Unity and Blender for authoring, exports to glTF and JavaScript/TypeScript, and is optimized for fast loads and small builds.
How does Needle Engine work with Unity?
Design scenes and logic in the Unity Editor and export to the web with a fast iteration workflow. Needle translates supported Unity features to web standards like glTF and JavaScript, so your content runs natively in the browser without WebGL player overhead.
How does Needle Engine work with Blender?
Use Blender to author assets and scenes, then export to glTF and run them with Needle Engine on the web. The pipeline focuses on PBR, lightmaps, instancing, and other optimizations so your Blender projects load quickly and look great online.
How is pricing structured?
Needle offers a free tier for evaluation and non-commercial use and paid tiers per seat for commercial use, team features, and support. Educational licenses are available. See the Pricing page for details.
Does Needle Engine support AR on iOS?
Yes. Needle Go brings interactive WebXR AR to iPhone and iPad through an App Clip powered by ARKit, without installing a full app. Needle also supports USDZ Quick Look for placing models in AR. Learn about iOS WebXR with App Clips.
Does Needle Engine support VR and WebXR?
Yes. Needle Engine is built for the web and supports WebXR for VR headsets and compatible browsers, so you can build immersive experiences that run natively without plugins.
Do I need Needle Cloud to host my projects?
No. You can self-host any Needle project as a static site or integrate it into your web app. Needle Cloud is an optional service for automation, optimization, and collaboration that makes shipping and updating projects easier.
