Building a game takes more than AI-generated code.

Genex is a desktop app for AI-assisted game development in Unreal Engine, Unity, Godot, or the browser.

It helps you move from a game idea to something playable by giving an agent the tools to set up the engine, build the game, and play-test it—not just write code snippets.

Key features:

• Engine workflows – build in Unreal Engine, Unity, Godot, or Roblox Studio, with agent-led setup and play-testing
• Model flexibility – use your Claude Code or ChatGPT subscription, or run local models
• Multi-agent development – mix Opus and GPT models across the main agent, workers, and reviewers
• Local 3D assets – create assets through the included Blender plugin
• Extensible tools – scaffold your own plugins and install shared plugins from GitHub

The project is early; the README explicitly says to expect rough edges.

It’s open-source (MIT license).
