Inspeck — Measure, Inspect & Edit 作者： Pulkit Mittal

Inspeck turns any live web page into something you can measure, inspect, and edit — without ever opening DevTools.

Measure — hover for exact sizes, spacing, and the distance between any two elements.
Inspect — click any element to read its real CSS, font, type scale, and color, with live contrast checks.
Edit — tweak values right on the page to preview a fix before it ships.
Capture — screenshot with notes to hand off the proof.

Built for designers, frontend developers, and anyone doing UI or design QA before something goes live. Works on any site, including elements inside iframes.

Private by design: Inspeck runs entirely in your browser. No accounts, no tracking — nothing ever leaves the page.
