Function12

Function12 is an AI-powered design-to-code platform that automates the conversion of UI designs into clean, production-ready front-end code. Its primary purpose is to streamline the handoff between designers and developers by reducing repetitive coding tasks and minimizing implementation errors. By integrating directly into existing design workflows, Function12 helps teams move from prototype to working interface more efficiently and consistently.

Function12’s DevMode (Plus) provides an enhanced inspection environment where developers can view component structures, spacing, typography, and design tokens in a way that directly maps to code. It supports modern front-end frameworks such as React and Next.js, and can generate responsive layouts with semantic HTML and CSS (including CSS-in-JS patterns depending on configuration). CodeGen automates the generation of reusable components, state-ready UI blocks, and layout logic based on design files, helping maintain design consistency across large projects. The platform also supports versioning and updates, so when designs change, developers can quickly regenerate or adjust code rather than rewriting from scratch.
