Judo

What Is Judo?

Judo is a design tool for creating and building mobile user interfaces, particularly for iOS apps, without writing code. It functions as a visual canvas-based platform where designers and developers collaborate on native UI elements using built-in SwiftUI components. Positioned in the website-builders category with extensions to mobile app development, Judo supports a free-paid pricing model, allowing teams to start without cost and scale to paid plans for advanced features. The tool integrates design and development workflows by enabling visual UI construction that generates production-ready SwiftUI code, reducing handoff friction between roles.

What Judo Does

• Provides a shared canvas for designing iOS app UI with drag-and-drop SwiftUI components.
• Supports design with real API data to create realistic interfaces reflecting live content.
• Offers real-time on-device previews to visualize designs on actual iOS devices.
• Generates SwiftUI code directly from designs for export to Xcode projects.
• Includes translation features for incorporating multilingual text into UI elements.
• Allows creation of reusable components or symbols for consistent design systems.

How Judo Can Be Used

• Design custom list rows or screens with API-driven data, preview them on devices, and export SwiftUI code for developer integration.
• Build prototypes of app features like buttons or forms, attach custom actions via URLs, and test responsiveness before full development.
• Set up server-driven UI sections in existing iOS apps by embedding Judo experiences that pull user-specific data.
• Collaborate on design systems by defining styles, colors, and reusable symbols across multiple screens.
• Streamline new project bootstrapping by exporting entire canvases to fresh Xcode projects with one click.

Who Is Judo For?

Judo serves product designers, iOS developers, and cross-functional teams working on native mobile apps who need to bridge design and code without manual translation. It fits solo creators prototyping SwiftUI interfaces, small teams reducing iteration cycles through on-device previews, and larger groups implementing server-driven UI for dynamic content areas. Experience levels range from designers familiar with visual tools to developers integrating generated code into Xcode. Projects involving custom data displays, multilingual support, or rapid UI experimentation benefit most from Judo's capabilities. Visit Judo
