UXPin ranks #3 in Design Systems & Component Libraries AI search.

UXPin is a code-backed UI design, prototyping, and design systems platform founded in 2010 in Gdansk, Poland, and acquired by private equity firm Xenon Partners in June 2020. Its defining feature, UXPin Merge, allows designers to prototype using real React components synced from Git repositories, Storybook, or npm packages—eliminating the vector-to-code translation gap common in static design tools. The platform supports the full product design lifecycle, from low-fidelity wireframing to high-fidelity interactive prototypes with conditional logic, variables, and states, through to production-ready React code export. In late 2025, UXPin introduced Forge (Merge AI 2.0), integrating GPT and Claude models to generate layouts using real coded components. Enterprise customers include PayPal, Amazon, T. Rowe Price, and Caterpillar. The platform is available as a web app and desktop application for Windows and macOS.
