Hearth is an open-source desktop engine for making games through a chat interface. Jake created it in 2026.

It has 100+ stars on GitHub and dozens of games shipped through it. You bring your own agent or CLI. There's no subscription, no cloud, and nothing for Jake to maintain.

Everything runs locally, so your projects never leave your machine. Take a look at hearthengine.com.
