02 · THE COMPOSITOR

Built for tight feedback loops.

Four primitives, infinite combinations. The whole stack is yours, none of it is hidden.

12ms recompile

Incremental shader compilation through a custom WGSL bridge. No spinner, no flash.

GLSL or AI

Hand-write fragment shaders or let the assistant draft a starting point from a one line prompt.

Versioned timelines

Every save is a node in a tree. Branch a happy accident, merge it back when it earns its place.

Export anywhere

Render a 4K mp4, a tile-ready png, or a self-contained web embed. One click, no pipeline.

03 · THE COMMUNITY

2,400 shaders, last week alone.

Fork anything in the gallery, watch how it was built, ship your remix back.

04 · EXPORT ANYWHERE

Three tiers. No surprises.

Free for solo experiments. Pay when you start shipping.
