Genex

Genex is a desktop application where artificial intelligence agents plan, build, and review Three.js games.

Genex is a desktop application designed for game development using artificial intelligence agents. It features a multi-agent workflow with visual judges, custom plugins from a community catalog, and a self-improving system that learns from every build. Users can connect their own Claude or ChatGPT subscriptions through Claude Code and Codex, or run free models locally using Ollama or Bonsai. The application currently targets Three.js games that export as static web bundles, with support for Unreal Engine and Blender coming soon. It integrates with various external services for asset generation, including Tripo3D, Meshy3D, Uthana Rigging, GPT Image 2.5, Nano Banana 2, MiniMax H3, and ElevenLabs. The software is open source under the MIT License.
