Hearth
Hearth is a free, open-source desktop application that enables agentic game development. Users describe the game they want in natural language; an AI agent (powered by models like Claude) generates and edits plain code files in a local project folder on the user's disk. The game runs live in a browser pane beside the conversation, automatically reloading with each change. Projects are standard folders that can be edited in any tool or handed off to a development team. It supports any browser-runnable game without templates or genre restrictions.
