Blueprint Packages
Reusable world kits. Package mechanics, assets, and systems once, then drop them into any world.
Package a mechanic, a system, or a whole slice of a world once, then drop it into any project. A day-night cycle, an inventory, a boss fight, a quest system: build it well, reuse it everywhere, and share it with everyone.
Build once, reuse everywhere
Capture a working system and bring it into any world in a click.
Whole slices, not just assets
Mechanics, logic, and content travel together as one kit.
A shared library
Use community kits, or publish your own for others to build on.
Part of one engine
Describe it. Gessa builds it.
Worlds, games, agents, and simulations, built from the same engine, in your browser, in minutes.
