Build universes. Break complexity.

Toyb is a modular worldbuilding engine for creators who think in systems.

Toyb was built out of frustration with tools that treat worlds like folders. I wanted something that thinks in systems. If you build in systems too, you'll feel at home here.

Join the first system builders.

Early members get direct access, private feedback channel, and lifetime beta perks.

Why Toyb

A calm interface for complex creative systems. Minimal surface, maximum control.

Projects as universes
