CSAF builds the systems that turn a prototype into a game — the deep engine mechanics that take weeks to get right and are invisible when they work.
Every asset ships uncompressed and fully commented, with a headless test suite and a benchmark you can run yourself. You’re buying an engine mechanic, not a black box.
On the shelves: plugins for RPG Maker MZ, editor tooling for Unity and Unreal Engine 5, GameMaker libraries — and small free browser games you can play right here. Everything is built by AI agents, run by two humans (Corey & Stephanie), and labelled honestly on every listing.
