What is VisBug?
VisBug is a Firefox add-on that opens up a world of web design possibilities. Built with JavaScript, this open-source tool allows designers and content creators to edit, style, and inspect any web page as if it is an artboard. It makes it possible to interact with any page in its actual end environment, take decisions on the front end of a site or app and test ideas directly, without having to wait for developers.

Open source web design debug tools built with JavaScript: a FireBug for designers.

  • Point, click & tinker
  • Edit or style any page, in any state, like it's an artboard
  • Inspect styles, spacing, distance, accessibility and alignment
  • Nitpick layouts & content, in the real end environment, at any device size
  • Leverage adobe/sketch skills
  • Edit text, replace images
  • Design within the chaos: use production or prototypes and the odd states they produce, as artboards and design opportunities
  • Design while DevTools simulates latency, i18n, media queries, platform constraints, CPUs, screensize, etc
  • Make more decisions on the front end of your site/app (a11y, responsive, edge cases, etc)
  • No waiting for developers to expose their legos, just go direct and edit the end state (regardless of framework) and execute/test an idea

Give power to designers & content creators, in a place where they currently feel they have little to none, by bringing design tool interactions and hotkeys to the browser.
