VisBug

Open source web design tools built with JavaScript - Simple as point, click & tinker - Edit or style any page, in any state, like it's an artboard - Hover inspect styles, accessibility and alignment - Nitpick layouts & content, in the real end environment, at any device size - Leverage adobe/sketch skills - Edit any text, replace any image (hi there copywriters, ux writers, pms) - Design within the chaos: use production or prototypes and the odd states they produce, as artboards and design opportunities - Design while simulating 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
