## Description

VisBug is an open source browser extension that brings powerful design debugging tools directly to your browser. Think of it as FireBug but crafted specifically for designers. With VisBug, you can point, click, and tinker with any webpage, editing text, replacing images, and adjusting styles in real-time — just like working on an artboard. It empowers designers to inspect spacing, alignment, accessibility, and layout across different device sizes and states.

Designed for creative professionals who want greater control without relying on developers, VisBug lets you manipulate the final rendered state regardless of the underlying framework. By integrating design tool interactions and hotkeys right in the browser, it facilitates rapid prototyping, nitpicking design details, and making front-end decisions with confidence. Whether working on production sites or prototypes, VisBug transforms the chaos into design opportunities, making it an essential tool for responsive, accessible, and dynamic web projects.
