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.
No setup, no boilerplate. Describe what you want, start playing, then make it exactly yours.
Tell Lud the game you're imagining, in plain words — a genre, a mechanic, a vibe.
Get a real, playable Three.js game running in your browser — no build step, no waiting.
Open the editor to change anything — actors, art, code — then export and ship it.
No engine ceiling. A production WebGPU runtime with Rapier physics — and the full ecosystem under it.
It works inside your project and proposes changes you can see — it never takes the wheel.
Your code, your assets. One click exports a web build or a desktop app — no lock-in.
Already pay for Claude Code, Cursor, or Windsurf? Connect it over MCP and use Lud's engine with zero hosted-AI cost on any plan.
No overage charges — hosted AI pauses at your limit. MCP never pauses.
Invite-only while we ship. Drop your email and we'll get you in.
