X-Ray Extensions·Design Inspector

See the design behind every website.

X-Ray Design Inspector helps you inspect and understand the visual systems behind the web — from typography and color to spacing, layout and assets.

Free to use · No account · Nothing leaves your browser

Understand the system.
Not just the surface.

Every website is the result of decisions: a type scale, a spacing rhythm, a handful of colours doing specific jobs. Those decisions are visible in the rendered page, but they are hard to read by hand.

X-Ray reads them for you — in the live page, at rest, without a build step or a screenshot. What it reports is measured, and what it cannot measure reliably it leaves out.

Features

Everything you need to inspect a website.

Six ways into the same page. Each one reads the live document — no build step, no screenshots, no guessing.

Inspect colors

Discover the colors used throughout a website — sorted by the job they do, with the contrast pairs that actually occur.

Design system

From pixels to a system.

X-Ray does not stop at single values. It looks for the decisions a page repeats — and hands them back as a system you can use.

FAQ

Questions, answered plainly.

Still unsure? X-Ray is free, needs no account and sends nothing anywhere.

What is X-Ray?
X-Ray Extensions is a small collection of focused browser tools. The first one is X-Ray Design Inspector, which reads the design of the page you are on: colour, typography, spacing, layout, assets and accessibility.
Is X-Ray a browser extension?
Yes. Design Inspector is a Chrome extension built on Manifest V3. It runs entirely in your browser; the analysis never leaves your machine.
What can I inspect with X-Ray?
Colours sorted by role and the contrast pairs that actually occur; font families, weights and the size scale; breakpoints, container widths and the spacing scale; images and SVGs with loaded-versus-displayed size; the machine-testable WCAG 2.1 criteria; the page’s CSS variables; and how many distinct values the page uses overall.
Does X-Ray work with any website?
It works on ordinary web pages, and it reads what is rendered — so it also works on pages built with any framework. It cannot run on browser pages such as chrome:// or on the Chrome Web Store itself, because Chrome does not allow extensions there. X-Ray says so instead of failing silently.

See the web differently.

X-Ray is completely free — every feature, no account, and nothing sent anywhere.
