Desktop app for game dev with AI.

Download

Genex is early: expect rough edges, and tell us about them in issues.

What it does

→ Use your Claude Code or ChatGPT subscription
→ Or run local models
→ Multi-agent game dev: mix Opus and GPT models across the main agent, workers and reviewers
→ Make 3D assets locally with the Blender plugin
→ Meshy, Tripo, ElevenLabs and more through the Genex tools router
→ Export anywhere, or publish to the web
→ Build in Unreal or Godot on your Mac with their plugins
→ Native C++ games soon

[!TIP] Have a tool your games need? Build a plugin and put it in the Genex Marketplace for everyone.

Contributing

You need macOS on Apple Silicon, Git and Node 24.

git clone https://github.com/genex-games/genex-desktop.git
cd genex-desktop
nvm install && nvm use   # Node 24, from .nvmrc
npm ci
npm run studio:dev -- start --profile first-run --fixture app-basics

The fixture runs the app with scripted models and sample games, so it needs no account. Read CONTRIBUTING.md before you open a pull request; coding agents start at AGENTS.md.

Build a plugin

Plugins give Genex's agents new tools: an asset generator, an engine bridge, a service your game talks to. The Blender and Genex tools that ship with the app are plugins too. From a Genex checkout:

npm run plugin:new -- my-plugin --out ~/studio-plugins   # scaffold it from the example
npm run plugin:doctor -- ~/studio-plugins/my-plugin      # check it the way Genex will

1. Try it: in the app, Plugins → Add → Load local plugin… and pick the folder.
2. Share it: push it to a public GitHub repository and publish a release for each version. Anyone can install it from there with Plugins → Add → Install from GitHub….
3. List it: open a pull request to genex-plugins. A maintainer reviews it, and it appears in every Genex app's Marketplace.

The plugin guide covers tools, panels, settings and accounts.

• Release operations: packaging, signing and publishing a release

Code signing policy

Free code signing provided by SignPath.io, certificate by SignPath Foundation.

Windows builds are signed only when GitHub Actions builds them from this repository's source, and a maintainer approves each release before it is signed. Until that signing is in place, Windows builds ship unsigned as a preview; every release lists each file's SHA-256 in SHA256SUMS.
