THE SYSTEM

One source of design truth.

Move between code, canvas and conversation while keeping control of every change.

01 / Semantic by design

Stable identities, editable boundaries and trusted bindings give each component a clear contract.

02 / Changes you can review

Inspect, validate and preview visual edits and AI proposals before confirming them.

03 / Code you can keep

Render and export validated documents with independent SigmaUI packages. Ordinary components never call a model.

SMALL PARTS. BIG POSSIBILITIES.

A considered toolkit.
An open canvas.

Compose foundations, layouts and website sections. Change your theme without changing your document.
