Describe a game.

Lud's AI writes your game as real Three.js on a production WebGPU runtime — then hands you an editable scene and every line of source.

Runs in the browser. Desktop apps for Windows & macOS.
How it works

A sentence in. A real game out.

No setup, no boilerplate. Describe what you want, start playing, then make it exactly yours.

Why Lud

Built for people who want a real game, not a toy.

It's real Three.js

No engine ceiling. A production WebGPU runtime with Rapier physics — and the full ecosystem under it.

  • Custom TSL / WGSL shaders & post-processing
  • Any npm package, glTF models, procedural meshes
  • If Three.js can do it, your game can too

AI that stays in its lane

It works inside your project and proposes changes you can see — it never takes the wheel.

  • Every step is inspectable and reversible
  • Two people + their agents on one project, live
  • Agents coordinate per file — no clobbering

You own everything

Your code, your assets. One click exports a web build or a desktop app — no lock-in.

  • Download your source on every plan
  • Web & desktop targets, no runtime fees
  • Run it anywhere — nothing phones home
