Once UI

The interface layer: an open-source design system for building coherent digital products.
Updated 5 hours ago

Once UI

Purpose: interface. Once UI is the open-source design system underneath much of the Dopler ecosystem. It provides the components, patterns and visual language needed to build product interfaces quickly without starting from zero every time.

Why it exists

Good product infrastructure should make coherent design easier, not slower. Once UI turns repeated interface decisions into reusable primitives so teams can spend more time on the product itself.

Role in the system

Once UI is the visual foundation. Aveiro, Orbit and other Dopler products can evolve independently while still sharing a coherent interface language.

In one sentence

Once UI helps us build the interface once, then reuse the thinking everywhere.
