Features

Everything you need. Nothing you don't.

A focused toolkit for inspecting, extracting, and copying CSS — without the bloat of a full DevTools replacement.

CSS in one click

Hover any element, click to lock, copy the entire stylesheet — only the styles that actually apply.

Box model, beautiful

Live, animated box-model diagram. Padding, border, margin — labelled, copyable, exportable.

Color picker built in

Eyedropper anywhere on the page. Hex, RGB, HSL. Auto-extracts the page palette.

Font identifier

What's that font? Hover to find out — family, weight, size, line-height — and view every unique declaration on the page.

Privacy first

No analytics in the extension. No tracking. No account required for the free tier. Your browsing stays yours.

Made by devs, for devs

Built by one developer who actually uses it. Tight loop, fast updates, no committee design.
