Layout.dev is an AI-powered platform that transforms simple text prompts into full React prototypes with clean, editable front-end code and an organized project structure. Leveraging Tailwind CSS and Shadcn/UI, it automatically generates modular UI components and wiring for modern, responsive interfaces, all within a browser-based editor, no local setup or server deployment required. An integrated code viewer and file explorer let users inspect, refine, and extend layouts, components, and styles in real time, while additional prompts drive rapid iteration and immediate previews. Projects are hosted online for seamless team collaboration, enabling stakeholders to review, comment, and co-edit prototypes without juggling multiple tools. By delivering production-quality code instead of static mockups, Layout.dev accelerates the journey from concept to working UI, making it easy to test designs, validate ideas, and jump-start development in seconds.
