Install, pin, select. That's it.

Select

Select any element and inspect the observed styles, structure, accessibility evidence, and implementation details behind it, right in a Chrome side panel.

Inspect

See identity, rendered dimensions, box model, typography, appearance, structural HTML, and computed CSS for that element in one panel.

Explore

Zoom out to the whole page: color and type inventories, assets, accessibility evidence, and technology signals — locate or export what you find.

Core Features

Five ways to see what's actually there

Inspect an Elements

Get the exact values, not a guess

Identity, rendered dimensions, flex or grid layout, box model, typography, appearance, safe structural HTML, and computed CSS for whatever you've selected.

Explore a System

Read the design system already in production

Colors, typography styles, CSS variables, and repeated spacing, radius, and shadow patterns — organized like a token sheet, pulled straight from the live page.

Understand Assets

Find every asset before you ask for it

Rendered images, CSS backgrounds, inline SVGs, and font evidence, with opt-in previews or downloads — kept calm and technical, not a media dashboard.

Review Accessibility

Catch what's reviewable, skip the score

Text and non-text contrast where resolvable, alt text, labels, headings, landmarks, target sizes, and duplicate IDs — flagged for review, never boiled down to a grade.

Implementation Evidence

See the CSS that's actually doing the work

Matching declarations, gradients, interaction-state rules, media queries, transitions, keyframes, component anatomy, and technology fingerprints — shown as evidence, not an analytics dashboard.

Privacy & Accuracy

Built to stay out of your data

Inspect Boss reports what the browser can observe. It doesn't read your page's private data, and it doesn't send anything without you asking.

Works locally by default

Analysis happens in your browser, on the page you're already looking at.

No automatic data sharing

No page data is sent anywhere unless you explicitly trigger it.

Never reads private inputs

Inspect Boss doesn't read form values, cookies, storage, tokens, or private messages.

Sharing is explicit, not automatic

Share with AI prepares content locally for you to copy, download, or send yourself.
