UXPin

UXPin is a design and prototyping platform built on real components, with AI assistance for generating interactive, production-accurate prototypes.

Overview

UXPin bridges design and development by letting teams prototype with the same components engineers ship — including coded React and design-system libraries. AI features generate layout variants from prompts, produce realistic content for testing and convert static designs into interactive states. Its conditional logic, variables and data-driven prototypes support complex flows that simple mockup tools cannot. Design tokens sync with code repositories, and usability testing is built in, so validation happens before handoff.

Key Features

• Prototyping with real coded components and design tokens
• AI generation of layouts, content and interaction states
• Conditional logic, variables and data-driven prototypes
• Design system management synced with code
• Built-in usability testing and participant recruitment
• Developer handoff with accurate specs and assets

Pricing

UXPin offers subscription tiers per user with a free trial. Advanced features like Merge integration and AI capacity are on higher plans.

Who Is It For

It serves product design teams that need high-fidelity, testable prototypes and want design-to-code consistency through shared components.

How It Works

Build prototypes using your real coded components or design-system libraries, with AI helping generate layout variants and realistic content for testing. Conditional logic, variables and data inputs make prototypes behave like the finished product. Usability tests run directly on prototypes, and handoff delivers accurate specs because everything is built from the same components engineers ship.

In Practice

The Merge integration is the reason engineering-led teams adopt it; plan the component sync before starting design work. Invest in a realistic data set for prototypes — testing with real-shaped data exposes issues lorem ipsum hides. Design systems stay maintainable when token ownership is shared between design and frontend rather than duplicated.

FAQ

Is UXPin free to use?

UXPin is paid with a free trial; individuals and teams choose plans based on collaboration and integration needs.

Does UXPin offer an API?

Yes, UXPin exposes APIs and its Merge technology for integrating coded components and design-system pipelines.

How does UXPin compare to alternatives?

UXPin’s component-based prototyping delivers far more realistic interactions than graphic-design tools adapted for UI work.

Does UXPin support coded components?

Yes, the Merge integration brings real coded components into the design environment, so prototypes behave like production interfaces. Teams with mature design systems get the most value, since designers compose with the same building blocks engineers ship.

Does UXPin support usability testing?

Yes, built-in testing lets teams validate prototypes with real users before development begins. Findings feed back into the design immediately, since prototypes are realistic enough to test interactions, not just visuals.
