Uxpin

Uxpin Merge is a design and prototyping environment that connects directly to your production UI code, allowing teams to design using real, reusable components instead of static mockups. It synchronizes with component libraries built in technologies such as React, Vue, Angular, or Web Components, and renders them as fully interactive elements inside the design canvas. Designers can drag and drop these coded components, configure their props and states, and assemble complex interfaces that behave exactly like the final product.

The platform supports design systems by consuming existing component libraries from repositories or design system sources, ensuring consistency between design and development. Because components come from production code, interaction states, responsive behavior, and accessibility properties are preserved in prototypes. This reduces the need for redlines and handoff documentation, as developers receive designs already aligned with the actual implementation.
