## What it is
VisBug is an open-source browser extension that brings design-tool interactions to any live webpage, letting designers point, click, multi-select, and edit text, styles, images, and layouts directly in the browser. It works across Chrome, Firefox, Safari, and Edge, enabling in-place design tweaks, hover inspection of styles and accessibility, and simulation of states like latency, media queries, and screen sizes.

## Use cases
- edit any webpage visually in the browser
- inspect styles and accessibility by hovering elements
- nitpick layouts and content at any device size
- test design ideas on production pages without waiting for developers
- simulate latency, translation, media queries, and screen sizes while designing
- traverse the DOM like layers in Sketch or Figma

## When to choose
- you are a designer or content creator who wants to tweak real pages in their end state
- you want to evaluate accessibility, responsiveness, and edge cases visually on live sites
- you want a complement to Figma or Sketch for working directly in the browser

## When to avoid
- you need a tool to design from scratch or prototype interactions
- you need a design system enforcer or authoring tool like Figma
- you need production code changes rather than in-browser visual edits
