Design Snap
A CSS Peeper alternative built for design tokens
CSS Peeper is a good way to look at a website's colors and fonts. Design Snap is built to take them with you: colors ranked by real usage, every :root variable, radii and shadows, exported as a Tailwind config, shadcn/ui theme, Style Dictionary tokens, Figma tokens or a prompt for an AI agent — from Chrome's side panel, 100% locally.

Design Snap vs CSS Peeper
Written by the developer of Design Snap — so here is the bias, stated upfront. Capabilities below reflect both tools at the time of writing (September 2026); where CSS Peeper is the better tool, the table says so.

|---|---|---|
| Colors ranked by real usage | Yes — by frequency in computed styles | No — unordered palette |
Every :root CSS variable listed |
Yes — with values and swatches | No |
| Typography, radii and shadows deduplicated | Yes | Partial — fonts only |
| Tailwind config export | Yes — free | No |
shadcn/ui + Tailwind v4 @theme export |
Yes — PRO | No |
| Style Dictionary v3 tokens | Yes — PRO | No |
| Figma tokens (Tokens Studio) | Yes — free | No |
AI export — prompt & AGENTS.md |
Yes — prompt free, AGENTS.md PRO | No |
| WCAG 2.1 contrast audit of the page | Yes — score free, full report PRO | No |
| Recolor the live page from its own variables | Yes — free | No |
| Stays open while you browse | Yes — Chrome side panel | No — popup |
| Element inspector on hover | Yes — with Copy CSS | Yes — visual |

When CSS Peeper is still the right choice
A comparison that never concedes anything is worthless. Two cases where switching would be a downgrade.
You want assets, not tokens
CSS Peeper surfaces a page's images and lets you grab them. Design Snap deliberately does not — it reads style decisions, not media. If downloading assets is your actual job, CSS Peeper does it and Design Snap will not.
You just want a quick glance
For “what blue is that, what font is that” and nothing more, CSS Peeper's popup is pleasant and immediate. Design Snap's value only starts to show when you intend to reuse what you found in code.
Where Design Snap goes further
A ranked palette, not a pile of colors
Colors come back ordered by how often they are actually used in the computed styles — so the brand color rises to the top instead of sitting next to a one-off border grey.
The variables the site actually declares
Every custom property on :root, with its computed value and swatch. On a modern site that is the real design system, and it is exactly what a colors-and-fonts popup cannot see.
Nine export formats
Tailwind config and v4 @theme, shadcn/ui variables, Style Dictionary v3, CSS :root, JSON, Figma tokens, an AI prompt and an AGENTS.md file — generated ready to paste, no cleanup.
A contrast audit, not just colors
Design Snap measures the text actually rendered on the page against WCAG 2.1, compositing translucent backgrounds before it measures, and reports text over images as skipped rather than guessed.
Other CSS Peeper alternatives worth knowing
Each solves a narrower problem. Picking well means knowing which question you are asking.
Chrome DevTools
Built in, free, and unmatched for inspecting one element in depth or debugging layout. It has no notion of a page-wide design system, and every value is copied by hand.
VisBug
An open-source visual design and debug toolbar: select, nudge, restyle and measure elements directly on the page. It is an editing tool, not an extraction tool — there is no token export at the end of it.
ColorZilla
An eyedropper and gradient generator. Perfect for picking one pixel's color; it does not rank colors by usage, read typography or shadows, or list CSS variables.
WhatFont & Fontface Ninja
Hover to identify a typeface. Excellent at that one question, and silent on colors, radii, shadows, variables and exports.

CSS Peeper alternative — FAQ
It depends on what you were using CSS Peeper for. For a quick visual look at a page's colors and fonts, CSS Peeper is already good at that job. For getting a whole design system out of a page and into code — colors ranked by real usage, every :root CSS variable, deduplicated radii and shadows, exported as a Tailwind config, shadcn/ui variables, Style Dictionary JSON or Figma tokens — Design Snap is built for that specifically. For deep debugging of a single element, Chrome DevTools remains unmatched.
Yes, there is a free plan with no account and no card: one-click extraction, the element inspector, a WCAG contrast score, live color editing and five export formats (CSS variables, tailwind.config.js, JSON tokens, Figma tokens and the AI prompt), limited to 3 sites per day and 5 saved snapshots. PRO is a single €9.99 payment for life — no subscription — and adds the shadcn/ui, Tailwind v4 and Style Dictionary v3 exports, the AGENTS.md export, the full contrast report, real dark-mode extraction and unlimited snapshots.
Yes. That is the main difference in practice. Design Snap turns the extraction into a ready-to-paste tailwind.config.js theme object (free), a Tailwind v4 @theme block, shadcn/ui semantic variables for globals.css and standard Style Dictionary v3 tokens (PRO). CSS Peeper shows you values to read and copy by hand; it has no design-token export formats.
No. CSS Peeper surfaces colors, fonts and assets, not the custom properties declared on :root. Design Snap lists every :root CSS variable with its computed value and a color swatch, and exports the whole set as a paste-ready :root block or JSON.
No. All analysis runs 100% locally in your browser, with zero third-party libraries. The only network calls the extension can make are to Google Fonts, to render the theme preview with real typefaces, and to polar.sh, to validate a PRO license key. It never transmits the pages you visit, their content or your browsing history, and there are no analytics inside the extension.
The side panel. Since version 3.0.0, Design Snap docks into Chrome's side panel and stays open while you browse, switch tabs and scroll — so a page and its tokens are visible at the same time. CSS Peeper works as a popup, which closes as soon as you click back into the page.
