About

UI Builder – Mockup Tool is a Chrome extension designed for creating UI wireframes and mockups directly within the browser. It allows users to sketch UI layouts on any live webpage or a new blank page using drag-and-drop, hand-drawn, sketch-style elements. The tool supports in-place text editing, smooth resizing, and easy screenshot capture (PNG or clipboard). It's built for designers, product owners, developers, and business analysts needing instant mockups without switching tools. Key features include privacy-first operation (100% local, no trackers), lightweight injection, and keyboard shortcuts. It's ideal for quick idea sketching, annotating client websites, teaching web design, and generating product screenshots for specifications and tickets.

Design Review

The Chrome Web Store page for UI Builder – Mockup Tool exhibits a clean, highly functional, and user-friendly design, characteristic of Google's platform aesthetics. The layout is intuitive, with a clear hierarchy of information, making it easy to navigate and understand the product's value. The use of Google Sans for headings and Roboto for body text ensures excellent readability and a modern feel. The color palette is predominantly white for backgrounds, dark grey for text, and Google Blue for interactive elements and accents, contributing to a professional and trustworthy appearance. The page effectively utilizes multiple screenshots and a video thumbnail to visually demonstrate the extension's 'sketch-style' UI and core functionalities, providing a comprehensive overview of the tool's capabilities. The overall design prioritizes clarity and ease of access to information, enhancing the user experience and effectively showcasing the product.
