Platform Capabilities

Everything you need to ship a game.

From prompt to playable build — LumenForge handles the entire pipeline.

✨

AI Code Generation

Describe your game in plain English. Gemini 2.5 Pro generates production-quality Three.js, physics, and game logic — then writes it directly into your project.

🌐

Browser-Native Runtime

StackBlitz WebContainers run a full Node.js environment in your browser tab. Zero install, zero latency, instant 60FPS previews as you code.

👥

Real-Time Multiplayer

Collaborate on the same codebase in real-time with Yjs CRDT sync. See teammate cursors, edits, and chat — all in the browser.

🎨

Asset Pipeline

Generate 3D models and textures from 2D images via Trellis 2.0 workflows. Export to FBX, GLTF, or directly into your scene.

Workflow

From idea to playable in minutes.

1

Describe Your Vision

Type a natural language prompt describing your game, scene, or mechanic. Use voice input for hands-free creation.

2

AI Forges the Code

Gemini generates modular, clean JavaScript/Three.js code. Files are created, dependencies installed, and the preview updates live.

3

Iterate & Ship

Refine with follow-up prompts or edit code directly in the Monaco editor. Export your build or deploy to the web instantly.
