uidx

Visual design tool where changes are diffable JSX stored in your repo

Desktopfreeglobal

uidx is a code-first visual design tool where every change is diffable JSX stored directly in a .uidx file inside your repo, letting agents and humans work together on the same design canvas, built on OpenPencil and Skia with MCP built in. It's built for developers and designers who want design changes to be reviewable and version-controlled alongside the code, instead of living in a separate tool like Figma.
