UI Builder + Mockup tool

UI Builder + Mockup Tool is a Chrome extension designed for creating quick, sketch-style wireframes directly within your browser. It allows users to drag-and-drop elements like buttons, inputs, headers, and dividers onto any live webpage or a blank canvas, enabling rapid prototyping without switching tools. Tailored for designers, product owners, developers, and business analysts, this tool is ideal for fast feedback during live demos, client calls, or brainstorming sessions.

The extension offers a true WYSIWYG experience, allowing users to edit text, recolor elements, and resize widgets seamlessly. Keyboard shortcuts enhance usability, while pixel-perfect exports let users save wireframes as PNGs or copy screenshots directly to the clipboard. Built with privacy in mind, UI Builder operates entirely locally within the browser, ensuring no network calls, analytics, or trackers interfere with the process. Its lightweight design ensures everyday browsing remains unaffected, injecting the tool only when needed.

UI Builder is particularly useful for sketching ideas before using heavier design software, annotating websites during live calls, teaching web design basics, and creating product screenshots for specifications or tickets. With straightforward installation and intuitive functionality, users can wireframe any webpage or blank canvas in just a few clicks, making it a versatile and efficient tool for web design tasks.
