Naked CSS vs CSS Peeper

CSS Peeper extracts styles, colors, and typography into a side panel for systematic inspection. Naked CSS overlays pixel distances, flex/grid gaps, and design tokens directly on the page for layout audits. Two tools, two different jobs — here's how they compare, and when to reach for which.

What is CSS Peeper?

CSS Peeper is a free Chrome extension by Sparkglare focused on systematic style inspection. Click any element on a page and a side panel surfaces its colors, typography, spacing, and assets — letting you extract design tokens, browse the whole-page color palette, and download images and icons. With 500,000+ installs and a 4.2-star rating across 470 reviews on the Chrome Web Store (last updated May 5, 2026), CSS Peeper is the long-tenured inspector of choice for designers ripping styles from production sites. It offers free core features and a premium tier with contrast scanning, typography hierarchy view, and gradient exploration. Naked CSS solves a complementary problem — measuring spatial relationships and gaps directly on the page, for free.

The short version

CSS Peeper is a side-panel inspector for systematic style extraction. Click an element, and the panel gives you colors, fonts, spacing, and assets — ready to copy or download. It's designed for designers ripping styles from production sites and exploring whole-page palettes. Naked CSS solves a different (but overlapping) problem: measuring spatial relationships directly on the page. Pixel distance between two elements, flex/grid gap labels, padding/margin visualization with per-side overlays, and :hover / :active state simulation — all rendered on-page rather than in a side panel. CSS Peeper answers “what colors and fonts does this site use?” Naked CSS answers “how far apart are these elements and which CSS variable produced this spacing?” Many teams keep both pinned — CSS Peeper for extraction, Naked CSS for audit.

What CSS Peeper got right

CSS Peeper has earned its place. With 500,000+ users, a 4.2-star rating across 470 reviews, and a recent update (May 5, 2026), it's the polished inspector designers reach for when they want to systematically extract styles. The whole-page color palette view is genuinely unmatched — you get a swatch of every color used on the site, ready to copy into your design tokens.

The typography hierarchy in the premium tier shows every font/size/weight combination across the page, which is the kind of audit-output no other Chrome extension produces with this clarity. The contrast scanner provides WCAG accessibility ratios for every text/background pair, going beyond what most inspect tools surface.

And the side-panel UX gives you a stable surface to read from while the page stays untouched — useful when you're comparing CSS Peeper's output against an external design source like Figma. If your job is to extract a design system from a production site, CSS Peeper is purpose-built for that.

What Naked CSS adds on top of CSS Peeper

Pixel distance between two elements

CSS Peeper inspects elements one at a time in a side panel. Naked CSS measures the spatial relationship between two elements. Click one element to lock the selection, hover any second element, and both horizontal and vertical pixel distances render on-page with labeled guide lines — the measurement an audit actually needs to flag a layout bug or verify a Figma spec.

Flex / grid gap detection on-page

Naked CSS hatches and labels every flex and grid gap region with its pixel value, rendered directly on the page so you can see at a glance which gap is wrong. CSS Peeper surfaces spacing values per-element in its panel, but doesn't visualize gaps between flex/grid children — where most modern-layout bugs actually live.

Interactive state simulation

Toggle Default, Hover, and Active states for any selected element with a single click. Inspect interactive styles without scripting them or moving your cursor over the element. CSS Peeper shows the static computed style for the element you click; it doesn't simulate pseudo-class states.

Inline CSS variable + design-token resolution

Every color Naked CSS surfaces is annotated with the CSS custom property name that produced it (e.g. --color-primary-500), inline, on-page, in the free tier. CSS Peeper's color-instance view (Premium) shows tokens in its side panel but not overlaid on the actual rendered element.

Free, with no premium tier

Every feature listed for Naked CSS in the comparison table is free. CSS Peeper's premium features (contrast scanner, typography hierarchy, gradient explorer, Smart Inspector) are excellent but paid. For teams who want full audit functionality without managing seat licenses, Naked CSS ships with everything included.

When to reach for which tool

Reach for CSS Peeper when…

  • You need to extract a whole-page color palette or typography hierarchy.
  • You're ripping assets (images, icons, gradients) from a production site.
  • You need a WCAG contrast scanner for an accessibility audit.
  • You prefer a side-panel UX that keeps the page untouched.
  • You're comfortable with a freemium model and need the premium features.

Reach for Naked CSS when…

  • You need pixel distance between two real elements, rendered on-page.
  • You need to verify flex/grid gap values against a design spec.
  • You want CSS variable / design-token resolution inline, not in a side panel.
  • You want to inspect :hover and :active states without writing JavaScript.
  • You want every feature free with no premium tier.

The honest answer: many teams use both. CSS Peeper for the discovery / extraction pass, Naked CSS for the measurement / verification pass.

How to add Naked CSS to your CSS Peeper workflow in 30 seconds

  1. 1Install Naked CSS from the Chrome Web Store — Add to Chrome. It's free and takes two clicks. You don't need to remove CSS Peeper — they coexist cleanly.

  3. 3Use CSS Peeper for the discovery pass — click around to extract the palette, typography, and asset inventory of the site you're auditing.
  4. 4Switch to Naked CSS for the verification pass — press Cmd+I, click your first element, then hover others to see pixel distances, flex/grid gaps, and the CSS variables behind every value.
  5. 5(Optional) Remap the Naked CSS shortcut to whatever doesn't conflict with your existing CSS Peeper muscle memory via the extension options page.
