Genex

Overview

Genex is an MIT-licensed desktop harness for making games with AI, starting with Three.js browser games. It coordinates a main agent, workers and reviewers, and you can mix Claude (via your Claude Code subscription), ChatGPT models or local models.

Visual judges check each change in the running build, and the harness updates its own skills from what it learns. A plugin system adds tools: Blender for local 3D modeling and rigging, Meshy, Tripo and ElevenLabs through its tools router, and one-prompt publishing to genex.games. Unity and Unreal plugins are listed as coming soon.
