CSS Peeper Alternatives: 6 Options Compared
Short version: if you want CSS Peeper's job done free and done better, CSS DNA covers the whole page rather than one element and exports what it finds. If you want the fastest possible hover-and-copy and do not mind paying once, CSS Scan. If you want to edit the page rather than read it, VisBug — also free. And DevTools remains the only tool here that shows you the cascade.
Why people look for a CSS Peeper alternative
CSS Peeper is a good tool with a specific shape: hover an element, get a tidy panel of its properties, plus the page's colors and downloadable image assets. It is free, it is designer-friendly, and for pulling a reference site's assets it is genuinely the best of this group.
The reasons people go looking are consistent:
- It reads one element at a time. If you want a site's whole design system — the full type scale, every spacing value, the shadow set — you are clicking a hundred times and transcribing by hand.
- There is no real export. You can copy values out; you cannot hand a Tailwind config, a set of CSS custom properties or a JSON token file to your codebase.
- Hover states, focus states and disabled states are invisible. Hover-based inspection cannot capture a hover style, because your cursor is the thing triggering it.
- The Pro tier's pricing is not published on their homepage, which makes it hard to plan around.
- No accessibility output. You get colors, but nothing tells you which pairs fail contrast.
If none of those bother you, CSS Peeper is fine and you should keep it. If one of them does, here is what actually replaces it.
The comparison
| Tool | Price | Scope | Captures states | Exports | Assets |
|---|---|---|---|---|---|
| CSS Peeper | Free (unpriced Pro tier) | One element + page colors | No | Copy only | Yes |
| CSS DNA | Free tier · Pro $5/mo | Whole page design system | Yes | Tailwind, CSS, SCSS, JSON, Figma, DESIGN.md | No |
| CSS Scan | One-time, $120 list | One element | Yes | Copy full rule | No |
| VisBug | Free, open source | One element, editable | Partly | Copy only | No |

The six, one at a time
1. CSS DNA — the closest free replacement, at a bigger scope
Built for the case CSS Peeper does not cover: reading a page's entire design language rather than one box. One click returns every color ranked by how much of the page it occupies, the font families with the weights actually rendered, the full type scale, spacing values, border radii, shadows and gradients.
The part that changes the workflow is the export. Those tokens come out as a Tailwind v3 config or v4 @theme block, CSS custom properties, SCSS variables, JSON, Figma / W3C design tokens, or a DESIGN.md brief you can hand to Cursor or Claude Code. Free tier covers element inspection, the eyedropper and the ranked palette; the exports, component capture, CSS audit and contrast auto-fix sit behind Pro at $5/month with a 7-day trial and no sign-up — it unlocks with a licence key.
It also reports WCAG 2 ratios and APCA Lc scores for every text/background pair, as a palette-vs-palette grid. Everything runs on-device; nothing is uploaded.
2. CSS Scan — the fastest hover-and-copy, if you will pay once
The smoothest interaction in this group. Hover anything and the complete rule appears instantly, ready to copy — including pseudo-classes and pseudo-elements, which most hover tools miss entirely. It is a one-time licence rather than a subscription: $120 list, discounted to $69 when we checked on August 12, 2026, covering three browsers.
3. VisBug — free, open source, and it edits
A Google Chrome Labs project (Apache 2.0). Where every other tool on this list reads, VisBug lets you drag, resize, restyle and re-type a live page directly — a design-review tool disguised as an inspector. Its inspect mode reports the essentials, but reading is not what it is for.
4. CSSViewer — the minimal free one
An old, small, free extension that shows a floating panel of the hovered element's CSS properties, grouped by category. No exports, no page-level view, no states. It does one thing and asks nothing of you.
5. Chrome DevTools — already installed, and the only one that explains why
Every extension here reads computed styles. DevTools is the only tool that shows the cascade: which rules applied, which were overridden, and what beat what. When a style is not doing what you expect, no extension will tell you why — this will. The color picker also reports the WCAG contrast ratio inline, and the Computed tab's Rendered Fonts section names the typeface the browser actually drew.
6. Fonts Ninja / WhatFont — if it was only ever about the type
Plenty of people install CSS Peeper for one reason: to find out what font a site uses. If that is the whole job, a dedicated font tool is lighter. WhatFont names the family, size, weight and line-height on hover; Fonts Ninja adds foundry and licensing links. Neither touches colors, spacing or exports.
Which one should you pick?
- You want a free CSS Peeper alternative that does more. CSS DNA — the free tier already covers element inspection, the eyedropper and the whole-page ranked palette.
- You need the site's images and illustrations. Stay on CSS Peeper. Nothing else here downloads assets.
- You copy single elements constantly. CSS Scan, if a one-time $69–$120 is easier for you than a subscription.
- You are rebuilding a design system, not copying a button. CSS DNA — the export is the entire point. See the six-step rebuild workflow.
- You want to mock up a change on a live page. VisBug.
- Something is styled wrong and you do not know why. DevTools. Always DevTools.
Is CSS Peeper still safe to use?
It is a well-established extension on the Chrome Web Store and has been for years. The question worth asking of any inspector — this one included — is what leaves your browser. Read the privacy disclosure on the store listing before installing anything that can see every page you visit. CSS DNA's answer is that nothing leaves: extraction runs on-device, there is no account and no analytics, which you can verify in our privacy policy.
Frequently asked questions
Is there a free alternative to CSS Peeper?
Several. CSS DNA's free tier covers element inspection, the eyedropper and a whole-page ranked color palette. VisBug and CSSViewer are free, and Chrome DevTools is built into the browser at no cost.
Is CSS Peeper free?
The Chrome Web Store version is free. A Pro tier exists but no price is published on their homepage, so we have not quoted one.
What is better than CSS Peeper?
It depends on the job. For extracting a whole site's design system and exporting tokens, CSS DNA. For the fastest single-element copy, CSS Scan. For editing a page live, VisBug. For debugging why a style lost, DevTools. For downloading a site's image assets, CSS Peeper is still the best of this group.
Can CSS Peeper export design tokens?
No. It shows values you can copy by hand. If you need a Tailwind config, CSS custom properties, SCSS, JSON or Figma tokens generated from a live page, you need an extractor built for that.
Does CSS Peeper work on Firefox or Edge?
CSS Peeper ships for Chrome. Coverage on other browsers varies by tool — CSS DNA runs on Chrome, Edge, Brave and Arc, with a separate Firefox build; VisBug and DevTools are available across Chromium browsers.
Can any of these capture hover and focus states?
CSS Scan and CSS DNA capture pseudo-classes and pseudo-elements directly. DevTools can, if you force the state manually through the :hov panel. Simple hover-viewers return the base rule only, because your cursor is what triggers the state you are trying to read.
Read the whole page, not one element
Colors, fonts, type scale, spacing and shadows — free to inspect, no account.
