AI Game Developer

AI Game Developer is an open-source game development application that builds, edits, and playtests games using AI agents.

AI Game Developer is an application and plugin set that builds, edits, and playtests games live inside Unreal Engine, Unity, and Godot. It connects AI agents like Claude, Cursor, and GitHub Copilot straight to game engines using the Model Context Protocol. The application operates locally for privacy or connects to hosted AI tiers for cloud-enabled workflows. Developers use natural language to execute scripts, generate assets, manipulate scenes, and edit components. It provides an open-source toolset with free unlimited MCP server access, alongside paid plans like Indie, Studio, and Studio Max for hosted AI power, extended context windows, and higher usage allowances.
