The Game Dev App —
one app, every engine.

The AI Game Developer app is your AI pair-programmer for Unity, Unreal Engine, and Godot. Install it, sign in with your subscription, pick an engine — and it installs and connects the right plugin for you. Available as a desktop app and as the gamedev CLI, sharing one account and subscription.

Install

RecommendedDesktop app

A polished agent for your desktop — voice input, chat history, and live MCP tool calls. Signed installers for Windows, macOS, and Linux, with auto-updates on launch.

…or the gamedev CLI

The same core in your terminal — same account, same subscription, same engine support. Requires Node.js 20.19+ or 22.12+.

npm install -g @baizor/gamedev
gamedev

Sign in with your subscription

Launch the app (or run gamedev) and choose Sign in. A browser window completes the OAuth device flow; your usage, history, and limits sync across the desktop app and the CLI. One subscription powers every engine.

How sign-in works in detail — and how to bring your own AI client — is on the Authentication guide.

Automatic engine setup

Pick an engine in the app and it does the wiring for you — no plugin wrangling:

  • Installs the matching Unity, Unreal, or Godot plugin into your project.
  • Connects it through ai-game.dev using your signed-in session.
  • Opens the editor so you can start prompting as soon as the status pill reads Ready.
  • Keeps the plugin updated as new versions ship.
Unity 2022.3+Unreal 5.5+Godot 4.3–4.5

Want to install a plugin yourself, or bring your own MCP client? Each engine’s advanced CLI + manual setup lives on its install guide: Unity, Unreal, Godot.
