CSS Xray от Ryonix Labs Inc.

CSS Xray turns any webpage into a readable CSS inspection surface. Move the pointer over an element to see its selector, dimensions, typography, inherited text styles, and the authored declarations that shape it.

The compact panel follows your cursor and keeps pseudo states and responsive rules attached to their source. Free inspection includes parent navigation, grid guides, and CSS copying.

Optional CSS Xray Pro adds pin-and-edit live CSS, side-by-side comparison, component output, HTML and CSS export, Tailwind conversion, and CodePen export. Pro costs $0.88 per month or $8.88 lifetime and supports two browser installations.

Inspection happens locally. Licence activation sends only the licence key and a random installation identifier to Ryonix Labs.
