Open source web design debug tools built with JavaScript: a FireBug for designers. - Point, click, move, resize & 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**
