Build product configurators, 3D product pages, web AR and games – exported straight from Unity and Blender.

Add interactivity, physics, animation and media with ready-made components – build rich, interactive scenes without writing code.

Choose your workflow:

Iterate at the speed of thought: see your changes in the browser in seconds – focus on your content, not on fighting with technology.

And it loads even faster – Needle’s FastHDR delivers photoreal lighting that stays smooth on any device, even phones.

Combine 3D scenes with responsive, accessible HTML – in any front-end or full-stack framework, or just plain HTML and CSS.

Start from a sample built for your stack:

One scene runs everywhere: iOS AR and Android AR on phones, full VR on Quest and Apple Vision Pro. Everywhere Actions add interactivity to AR – even as interactive USDZ in iOS Quick Look, with no app install.

Bring beautiful lighting to the web. Use the powerful lightmapping tools inside the Unity Editor or Blender, and export them with Needle.

Needle supports the full PBR (physically-based rendering) workflow – transmission, sheen, anisotropy and more – plus MaterialX for standards-based, portable materials.

Custom shaders allow you to create your own style, and can be exported directly from Unity's Shader Graph. Work with textures, subgraphs, noise, vertex offsets & custom code.

We efficiently compress models, textures and animations for optimal performance, even on low-end devices. At runtime, your content loads in parts, to keep wait times short and pages snappy.

You decide how your content is split up into individual interactive 3D files and scenes. It's easy to load them only when you need them.

One build runs everywhere – desktop, phone, tablet, and headsets like Apple Vision Pro and Quest 3 – straight in the browser, with no app install. New devices are supported out of the box.

Create anything from product configurators to sandbox games. Use all the capabilities of the modern web. Thousands of spatial websites are already powered by Needle.

Build collaborative apps without friction. Switch to more advanced networking solutions when you actually need them.

Networking capabilities are included at no additional cost. Persistent rooms, avatar synchronization, and voice-over-IP just work.

Many core components support multi-user scenarios, and we provide many samples to get you started.

Needle has a vibrant community of creators, artists, and developers. Join us! We're excited to see what you build.
