Inspeck

Inspeck이란?

Inspeck turns any live web page into something you can measure, inspect and edit — no DevTools required. Hover to measure spacing and sizes. Click any element for its real font, color and CSS. Then tweak values inline to preview a fix before it ships. It's design QA without the tab-switching — catch the 2px that drifted, the off-brand pink, the heading that's a size off. Works on any site and runs fully in your browser. Free Chrome extension.
