Claude Sonnet 4.5 + Ant Design + UXPin Merge UI Design Workflow
Getting Started: Setup and Requirements
Required Tools and Accounts
To begin creating UIs with this workflow, you’ll need three essentials: a UXPin Merge account, access to Claude Sonnet 4.5, and the Ant Design library. Luckily, UXPin integrates these tools seamlessly – no need for separate subscriptions or API keys.
A UXPin subscription or trial unlocks Merge’s code-backed prototyping features and the AI Component Creator. It also provides built-in access to Claude models and the Ant Design library. Additionally, you’ll need a modern web browser and a reliable internet connection since UXPin Studio operates entirely in the cloud.
Once you’ve got these in place, you’re ready to set up UXPin Merge with Ant Design.
Setting Up UXPin Merge with Ant Design
After gathering the necessary tools, log into UXPin and head to the "Merge" section to start a project using code-backed components. From there, navigate to the libraries section and select the built-in Ant Design library – custom imports are only necessary if you’re working with a modified version of the library.
Once selected, the Ant Design library provides a comprehensive set of React components that you can drag and drop onto your design canvas. These components are functional, complete with states, props, and logic. When you’re done prototyping, use the "Get Code" feature to export production-ready React code, including all dependencies.
Connecting Claude Sonnet 4.5
To integrate AI into your workflow, open the AI Component Creator, choose Claude Sonnet 4.5, and set "Ant Design" as your target library. This integration uses the claude-sonnet-4-5 model identifier via Claude’s API. Pricing is straightforward: $3 per million input tokens and $15 per million output tokens.
With this setup, you can enter prompts like "create a user registration form with email validation" to see Claude transform your request into a fully functional Ant Design layout. These AI-generated components sync directly to your UXPin design system, allowing for further customization and interactive prototyping.

Building UI with Claude Sonnet 4.5 and Ant Design
Generating Design Ideas with Claude Sonnet 4.5
To kick off your workflow, open the AI Component Creator in UXPin and clearly define your UI needs. Treat Claude like a seasoned expert who thrives on precise instructions. For example, instead of a vague request like "create a dashboard", go with something detailed: "Generate a responsive dashboard layout using Ant Design components, including a data table for user metrics and a sidebar for navigation."
Claude takes your input and converts it into React layouts, using real Ant Design components. These aren’t just static shapes – they’re interactive, code-backed prototypes that sync directly into UXPin Merge.
For more intricate layouts, consider using XML tags to structure your prompts. Wrap specific details in tags like <branding>, <layout>, and <components> to help Claude interpret your requirements effectively. Providing 3–5 examples of Ant Design implementations can also ensure the output aligns with the library’s visual and functional standards.
Once Claude delivers the initial layouts, you can refine them further using Ant Design’s component library.
Customizing Ant Design Components
After Claude generates the layout, you can fine-tune it directly in UXPin. The UXPin Properties Panel makes it easy to adjust component props – whether you’re toggling between variants, changing sizes, or tweaking colors and states. Every change you make in the design tool translates seamlessly into the final code.
UXPin reports that designing with Merge components is 8.6 times faster than traditional vector-based tools. This efficiency comes from being able to edit props directly, cutting out the manual design guesswork. Once your customizations are complete, Spec Mode lets you share exact JSX code, dependencies, and functions with developers.
With your components tailored, the next step is to assemble them into an interactive prototype.
Creating Interactive Prototypes
Use drag-and-drop functionality to place Ant Design components onto the canvas and build your prototype. Add variables, conditional logic, and expressions to simulate real-world scenarios, creating a prototype that’s nearly production-ready.
This streamlined process can dramatically reduce development timelines. Mark Figueiredo, Sr. UX Team Lead at T.Rowe Price, shared:
"What used to take days to gather feedback now takes hours. Add in the time we’ve saved from not emailing back-and-forth and manually redlining, and we’ve probably shaved months off timelines."
Larry Sawyer, Lead UX Designer, also highlighted the impact:
"When I used UXPin Merge, our engineering time was reduced by around 50%."
Once your prototype is finalized, you can export it as code-ready React files or open it directly in development environments like StackBlitz with just one click.
Previewing, Testing, and Exporting Prototypes
Previewing UI Designs
UXPin’s preview feature allows you to interact with your prototype just as it would function in production. By using code-backed Ant Design components, the preview replicates live production states, dynamic content, and interactivity. You can use the browser preview to check how forms respond, test date pickers, and verify conditional UI behaviors.
This high-fidelity approach makes stakeholder feedback more actionable. As Erica Rider, Former UX Lead EPX at PayPal, shared:
"C-suite people and directors can give us stronger feedback about the ultimate direction because they experience the features and goals of these prototypes rather than just commenting about how these boxes don’t look like a text field."
After previewing, the next step is to validate your design through thorough testing to ensure it works as intended.
Testing for Functionality and Usability
Once you’ve reviewed the live preview, it’s time to test your prototype against real-world scenarios. Incorporate variables and expressions to simulate actual user behavior, and avoid relying on static screens that only show ideal conditions. Focus on testing edge cases, error states, and complex user flows to identify potential issues before development begins.
UXPin’s built-in commenting system makes it easy to gather feedback from team members like designers, product managers, and engineers. You can tag specific people, assign tasks, and mark comments as resolved – all directly within the prototype. For usability testing with external users, password-protect your prototype links to maintain control over access.
Brian Demchak, Sr. UX Designer at AAA Digital & Creative Services, highlighted the benefits:
"It has increased our productivity, quality, and consistency, streamlining our testing of layouts and the developer handoff process."
Exporting Code-Ready Prototypes
After validating the prototype through preview and testing, the final step is exporting your production-ready components. When your design is complete, UXPin allows you to export it as production-ready React code along with all necessary dependencies. You can use Spec Mode to copy clean JSX code or export it directly into your project. There’s even an option to launch it in StackBlitz with a single click.
Since UXPin Merge uses the same Ant Design components for both design and development, there’s no need for a translation layer. This means your design elements translate directly into production code, eliminating manual redlines and reducing back-and-forth communication. This streamlined handoff process helps teams save months of work and significantly cuts down on engineering time.

Benefits of Using Claude Sonnet 4.5 + Ant Design in UXPin Merge
Building on the streamlined workflows mentioned earlier, this combination offers several advantages that can transform enterprise-scale design processes.
Faster Prototyping and Delivery
This approach drastically cuts down on the manual effort involved in UI construction, which often slows enterprise teams. With Claude Sonnet 4.5, text prompts are turned into production-ready Ant Design React components. This means you can create complex interface layouts in just minutes instead of hours. Since these components are backed by real code, the prototypes are immediately functional, eliminating the need for time-consuming rebuilds later.
The results are impressive. Using UXPin Merge can make project development up to 10 times faster compared to traditional methods. Teams can move from initial concepts to testable prototypes in just one day, enabling quicker iteration cycles and more effective feedback from stakeholders.
Better Collaboration Between Designers and Developers
When both designers and developers work with the same Ant Design components, communication gaps shrink. There’s no need for a “translation” layer between design and code because the prototype is essentially the actual code. Developers can grab clean JSX directly from the design interface, complete with all the properties and dependencies configured by designers.
Mark Figueiredo, a Senior UX Team Lead at T. Rowe Price, highlighted this efficiency:
"What used to take days to gather feedback now takes hours. Add in the time we’ve saved from not emailing back-and-forth and manually redlining, and we’ve probably shaved months off timelines."
