UXPin

UXPin is an AI-powered, code-based design and prototyping platform where designers work with real production React components instead of vector approximations. Its Merge technology syncs a team's design system from Git or Storybook onto the design canvas, its Forge AI assistant generates and iterates UI constrained to that design system, and export is production-ready JSX referencing components already in the codebase. The developer surface is the open-source Merge toolchain - the @uxpin/merge-cli npm package that analyzes a component repository and pushes components to UXPin - rather than a public REST API.

UXPin is profiled on the APIs.io network. Tagged areas include Company, Design, Prototyping, Design Systems, and React.

UXPin’s developer surface includes documentation, getting-started guide, pricing, engineering blog, changelog, signup flow, support, and 17 more developer resources.
