Napkins.dev, represented as an open source project, automates the conversion of design drafts to code by integrating Meta's Llama4 visual language model with the Together AI inference service. The tool specializes in outputting the complete HTML/CSS/JavaScript code structure for the Next.js framework, and its technology stack contains three core technology layers:
- visual identity layer: Llama4 model to analyze UI elements (e.g. buttons, forms, etc.) and their spatial relationships in uploaded screenshots
- code generation layer: Build a React component tree and apply Tailwind CSS style rules based on the recognition results.
- Previewing the debugging layer: Real-time sandbox environment for code generation via Sandpack
Typical examples include converting login page wireframes into fully functional Next.js components in 15 seconds, with responsive layout fundamentals and interactive element event bindings included by default in the generated code. This is 8-10 times more efficient than traditional manual coding, and is especially suited for rapid proof-of-concept design.
