Open Source for Everyone

The Open Source movement was a revolution for programmers, allowing them to freely reuse existing tools and systems.

With the advent of mass market AI, anyone can build with Open Source. Every page on this site has a "Source" button in the top corner. You can download the source prompt for any game, change it for your needs, and produce a fully-functional customized game.
