What is UXPin?
UXPin Merge is a UI builder and prototyping tool designed specifically for developers and technical designers who want 100% parity between design and code. The tool allows users to drag and drop coded React.js components that render as fully functional UI, or use AI to generate code-backed layouts. Components come directly from Git repositories or Storybook, ensuring they look, feel, and function exactly like the real product end-users will experience.
Key features include interactive prototyping with built-in interactions and responsiveness, design system development with auto-generated documentation linked to code components, and clean front-end code generation that exports fully functional React/JSX code with no additional translation needed. The tool supports open-source libraries like MUI, Tailwind UI, Ant Design, and Bootstrap, plus allows integration of proprietary libraries synced via Git, Storybook, or npm. AI-powered components include the AI Component Generator for prompt-based layout creation and the ability to paste Tailwind code to get ready layouts.
UXPin Merge is for developers who want to build UI 8.6x faster without waiting for designers, technical designers who want to get the most out of their component library, and teams bridging the gap between design and development. Users can view and edit projects directly in StackBlitz for faster product development, reuse interactive components from top React libraries, and maintain consistency across products by importing their component library to reuse code.

Frequently asked questions about UXPin
What component frameworks does Merge support?
Currently, Merge supports React.js only. You can try to run other frameworks wrapped in React.js but the tool cannot guarantee it will work properly.
What code languages does Merge support?
Merge supports React.js components defined in three ways: JavaScript with properties defined using PropTypes, JavaScript with properties defined using Flow type annotations, and TypeScript with properties defined using TypeScript types.
Does Merge support different branches of the code repository?
No, currently Merge works only on the master branch of the code repository. Other branches are not supported at this time.
How can I see my code component in my UXPin account?
There are two ways to connect your design system through Merge to UXPin: 1) Use continuous integration tools (recommended), or 2) Use the push command in the terminal with a token stored inside. More details are available in the integration documentation section.
Can I change the position of nested components?
Yes, you can change the position by dragging components on the layer panel. This changes the position of the layer and the components. You can also nest or unnest components on the layer panel.
What is the newest version of Merge?
The newest version of Merge package is 3.0.0. If you installed Merge in your design system, you can check the version in the package.json file of your design system.
Can I add my own coded library or Design System?
Custom libraries are available for Enterprise plans. You can connect your own components from Git or Storybook to design directly with production code, maintaining consistency across your products.
Who owns the code generated in UXPin?
You do. Any production-ready code or customized components created in UXPin belong to your team, just like when you use open-source libraries in your own projects.
Why can't I type into the text field component on the preview?
This is a common symptom of a Controlled form control without the correct @uxpinbind annotation. Read more about Controlled and Uncontrolled form controls in the React.js documentation to fix this issue.
Can I use UXPin without AI?
Yes. AI is included by default, but all core design and prototyping features work independently of AI. You can use the tool for traditional design and prototyping without relying on AI features.
