Needle Cloud
Manage and optimize 3D files
and host your spatial web apps.
Magically optimized
Upload a 3D file and get a web-ready version automatically — a fraction of the size, loading in a fraction of the time, on any device.
- Right-sized for every device. We build lighter levels of detail for meshes and textures and load them only when needed — fast on phones, crisp on desktops.
- Presets for any project. Pick hero quality for a product showcase, or lighter settings for props in a large scene.
- No manual work. No remeshing, no exporting variants by hand — it all happens automatically.
Your 3D files,
ready for the web.
Upload your 3D assets in a variety of formats, including GLTF, USD, FBX and VRM . We prepare them for various usecases using our state-of-the-art optimization pipeline.
You can embed them in your website, share links with others, or download them for further use.
Here are some examples:

Ultra-fast HDR environments
Realistic image-based lighting that loads in a fraction of the time. FastHDR environment maps load up to 10× faster than EXR, use around 95% less graphics memory, and stream in smoothly without freezing your scene — all built on open standards.
Browse 20+ ready-to-use environments in 1k, 2k and 4k, and drop them straight into your three.js or Needle Engine project — or compress your own EXR or HDRi images on Needle Cloud.
The time you save with FastHDR goes straight back into image quality. A crisp 4K environment now loads as quickly as a low-resolution one used to — so even ultra-detailed 8K scenes become practical on the web, without slowing your project down.
Host your spatial web apps made with Needle Engine
Bringing your spatial web apps online is now easier than ever. Say goodbye to manual server setups – host your apps directly on Needle Cloud.
Upload a new version with a single click, right from Needle Engine for Unity and Blender. Our global CDN ensures your apps load fast, no matter where your users are.
What people say
Unbelievable Unity editor integration by an order of magnitude, and as straightforward as the docs claim. Wow.
Needle Engine has been the most flexible, easy to implement, and solid web AR implementation I've come across.
Export scenes from Unity, leverage the 3D editor ecosystem, then render them in your own web-based engine.
My workflow has been optimized 10X ever since I started using Needle.
We have around 12 products used globally, all made with Needle. It's been absolutely instrumental in getting them out the door — and makes the whole workflow so easy.
It just works on every browser — that's the mad thing. And it can be used by people like me who can't code.
When we saw it's multiplayer, we started screaming in our office. Amazing support, amazing community.
The best thing I've seen since Cinemachine in Unity. Unity should acquire this.
Simply the best Three.js extension I've ever tested. Bravo!
It is just soooo good, thanks for creating such an amazing dev tool!!
This is amazing — if you're curious about WebXR with Unity, this will help us get there.
needle.tools is a wonderful showcase of what Needle contributes to 3D on the web. I just love it.
Played with this a bit this morning — pretty magical.
Huge for WebXR and shared, immersive 3D experiences — and the AR part worked flawlessly.
You animate something, press export, and it's in the browser. You share a URL and say join me — it always impresses people.
Needle addressed all the issues I had. At the MIT hackathon, we were by far the fastest team.
I tried Adobe Aero, 8th Wall and Niantic Lightship — all dropped or needed app-store downloads. With Needle's App Clip tech I found the right path.
I tested it in your engine and it worked on the first try — which I haven't experienced in any other engine.
Game changer when working with three.js. Feels like magic.
A must have for any threejs developer! Makes debugging much easier.
