“Frontend” is the code repository backing The Guardian’s main website (theguardian.com), especially the user-facing frontend. It is built to deliver fast, accessible, responsive, and inclusive web pages to a large audience. The backend uses Scala with the Play Framework, responsible for server-side rendering / API endpoints etc., while the client side assets (JS, CSS etc.) are built via a client-side build process. It emphasizes audience-first design: performance, accessibility, maintainability.
