UXPin

UXPin is a powerful, code-based design and prototyping tool that enables UX designers, product managers, and cross-functional product teams to create everything from rapid wireframes to fully interactive, high-fidelity prototypes — all within a single, web-based platform. Unlike traditional image-based design tools, UXPin builds designs using HTML, CSS, and JavaScript under the hood, which means the prototypes designers create closely mirror how developers will actually build the final product, significantly reducing the gap between design and engineering. The platform supports advanced features like variables, conditional interactions, expressions, interactive states, and a data generator, giving teams the ability to simulate complex, real-world user experiences without needing to write code themselves. UXPin also includes robust design system management capabilities, allowing teams to document, share, and maintain consistent UI components and style guidelines across projects, while a built-in spec mode and Jira integration streamline developer handoff. It is particularly well-suited for small to mid-market companies in industries like computer software, information technology, marketing, and design, serving roles ranging from UX and UI designers to product managers who need to communicate requirements visually. Whether the goal is conducting user testing, gathering stakeholder feedback through shareable previews with commenting, or maintaining a scalable design system, UXPin consolidates the entire UX design lifecycle into one cohesive workflow.
