Prosper

Prosper is a self-hosted AI game builder that creates 2D and 3D web games from your plain language description. You describe the game you want, and Prosper writes the game, plays it in a headless browser to test functionality, and repairs any issues it finds.

It runs on your own computer (Mac, Windows, or Linux) and requires an AI model key from a provider you choose. Every game is play-tested by a machine before you see it, ensuring it starts, responds to input, and reaches a win or lose condition. The games Prosper builds come with full source code and use licensed assets you own.

Prosper is designed for people who want to create playable web games without coding. It supports both 2D and 3D games, although 3D support is still in progress. You can open, edit, and sell the games Prosper builds. The product includes 44 starter templates and about 99 add-ons to help you get started.
