Design Snap is a browser extension available on the Chrome Web Store that functions as a design token extraction and theme generation tool for websites. Its primary purpose is to allow designers and front-end developers to analyze the visual design system of any webpage without manually inspecting code through browser developer tools. The extension operates entirely locally within the browser, with no data sent to external servers, and does not require an account for its free features. The tool offers several core capabilities organized into distinct tabs. The Theme Tab automatically analyzes a page to classify design tokens by role, including colors (background, foreground, primary, secondary, muted, accent, border, destructive), typography (font families, sizes, weights, line-heights), and spacing values like border radius. It provides a live preview of these tokens rendered on sample UI components such as buttons, cards, inputs, and badges. The extension can detect a site's existing dark mode or generate a dark theme from the light theme when one is not present. An Element Inspector allows users to hover over any element to view its computed styles, including color, background, font, size, border-radius, and box-shadow, with the ability to copy a clean CSS block. The Design DNA Card feature generates a shareable PNG snapshot of a site's design system, displaying the hostname, logo, fonts, radius, and six dominant colors. Design Snap supports exporting extracted tokens in six formats: JSON in Style Dictionary format, CSS Variables, Tailwind config objects, Tailwind v4 syntax, shadcn/ui blocks, and Figma Tokens Studio JSON. The Tailwind v4 and shadcn/ui export options are part of the PRO tier. The free version includes token extraction, color role classification, typography and radius analysis, CSS variables, JSON/CSS/Tailwind/Figma export, the element inspector, and one saved snapshot in the Snapshot Library. The PRO version, available from 4.99 euros per month, unlocks Tailwind v4 and shadcn/ui export, a dark mode toggle, full-resolution Design DNA cards, and unlimited snapshots. Typical use cases include reverse-engineering a competitor's design system, extracting tokens for reuse in a new project, or quickly understanding the visual structure of a reference site. The workflow involves navigating to a target webpage, activating the extension, and using the Theme Tab to view and export the extracted tokens. The extension is offered by developer hudayfa.k.pro, has a size of 1.73 MiB, supports English and French languages, and was last updated on July 15, 2026. It includes in-app purchases for the PRO features.
