CSS Peeper: new tool for Web Designers
How often each product is chosen within a category, 0–100% relative to the other.


As answered by people managing Code Specimen and CSS Peeper.
Code Specimen's answer
Code Specimen reads a web page for you. Hover over any heading, button or image and its font, colours, spacing and CSS appear in a side panel beside the page, each value with its own copy button, so you never need to open DevTools or dig through someone else's stylesheet. The panel sits beside the site rather than on top of it, so nothing you're looking at gets covered, and opening it never reloads the page. Four tabs cover the whole job: Element for one element in full, Type for the whole type scale, Colours for the real palette with contrast ratios, and Assets for every image on the page. It's completely free, with no account, no analytics and no ads.
Code Specimen's answer
Because the features people actually install a tool like this for are free. Copying a colour or a font size isn't locked behind a plan, and there's no account to create and no daily limit. The deeper tools are free too: copying a whole component as HTML and CSS with its hover and focus styles and media queries, editing values live, seeing hover and focus states, finding every use of a colour, and an eyedropper for colours inside photos. It's also built to be trusted: no analytics, no ads, it runs only when you open it, and it asks for four browser permissions at most. Teams using Tailwind can convert any component into Tailwind classes with their own Anthropic, OpenAI or Google Gemini key, and Code Specimen charges nothing for it.
Code Specimen's answer
Designers and front-end developers. Designers use it to study a site's type scale and palette, since those give a site its feel. Developers use it to get exact values in px or rem, or to copy a whole component with its hover and focus styles, without opening DevTools. It also helps anyone moving a site to a new platform who wants to take the existing look with them, and teams that build with Tailwind.
Code Specimen's answer
Code Specimen is a browser extension for Chrome and Firefox, built on the browser's own extension APIs: the side panel, active tab, scripting and storage permissions. Its optional Tailwind conversion connects to the Anthropic, OpenAI or Google Gemini APIs using the user's own key.
Code Specimen's answer
Code Specimen is free, has no accounts and no analytics, so there's no customer list to draw from, and naming companies without permission or proof would be inaccurate. If SaaSHub forces an answer, ask the founder whether any known teams use it and are happy to be named.
