3D, built for the browser.

Three.js lets us bring real 3D into the browser — product configurators people can rotate and customise, data visualisations that respond to interaction, immersive brand experiences that stand out from a flat page. We build it to stay smooth on real devices, not just on a dev machine, with sensible fallbacks for anyone on older hardware.

What we build with Three.js

Why Three.js with Level UI

• Real 3D with zero install — runs straight in the browser
• Tuned for performance, not just for demos
• Works alongside your existing Next.js / React stack
• Graceful fallbacks for lower-powered devices
• Pairs cleanly with AR via WebXR, ARKit or ARCore

Frequently asked questions

• Will 3D slow down my site?+

  Not if it is built properly. We optimise geometry, textures and render loops, lazy-load the 3D scene, and provide a lightweight fallback so Core Web Vitals and mobile performance stay solid.

• Can Three.js work with our existing Next.js site?+

  Yes. We integrate Three.js scenes directly into a Next.js / React front end, so the 3D layer sits on top of the site you already have rather than replacing it.

• Do you need a 3D model, or can you build one?+

  Either. We can work from your existing 3D assets or model and texture new ones, matched to your brand and optimised for the web.
