Font Finder

Every font the page actually draws, with weights, sizes, the font file and a Google Fonts link. It tells you when the first font in the CSS failed and the browser fell back to another.

Color Palette

The colors a page really uses, ranked by how much of it each covers and named in plain words. Copy them as hex, CSS variables or JSON, plus the site’s own color tokens when they are readable.

Animation Detector

GSAP, ScrollTrigger, Three.js, Lenis, Lottie and more, with versions and live counts of tweens, ScrollTriggers and CSS animations. When it finds nothing it says why, instead of guessing.

How they work

You click the toolbar icon, and the extension runs a short, read-only check on the page you are looking at. The answer appears in the popup. That is the whole thing. They change nothing on the page, store nothing, and do nothing on tabs you have not clicked them on.

Extension or web tool?

Use the extension while you browse. When you need the full answer (every font file, every easing curve, the WebGL scene), the popup links to Enrichr, which captures it and hands it to Claude, ChatGPT or Cursor.

FAQ

Are the Chrome extensions free?

Yes. All three are free, need no account and have no ads. Each popup links to Enrichr for a deeper capture, which is optional and has its own free plan.

Do the extensions collect my data?

No. They have no analytics, no account, no storage and make no network requests of their own. They run a read-only check on the tab you click them on and show the result in the popup. The one thing that can leave your browser is a link you choose to click. See the extension privacy policy.

What permissions do they ask for?

Two: activeTab, which gives access to the current tab only after you click the icon and only until you leave the page, and scripting, which runs the check in that tab. There are no host permissions, so Chrome shows no "read all your data on all websites" warning.

Can I use them on a page behind a login?

Yes, because they run in your own browser on the page you are looking at. They do not work on Chrome’s own pages (chrome://), the Web Store or some PDF views, which Chrome blocks for every extension.

Why does the Animation Detector sometimes find nothing?

An extension can only see what a page still exposes after it has loaded. Plenty of modern sites bundle GSAP, Three.js or Lenis without leaving a global behind, so no extension can see them. Enrichr’s capture hooks in before the page’s own scripts run, which is why it can.

Why three separate extensions instead of one?

Each does one job, so each asks for nothing beyond that job and is easy to find and understand. They share the same design and the same privacy rules.

Which browsers do they work in?

Chrome. Other Chromium-based browsers that run Chrome extensions, such as Edge and Brave, should work too, but we test only in Chrome and Chromium.

What is the difference between the extension and the web tool?

The extension is unlimited, works on logged-in pages and localhost, and needs an install. The web tool works from any device with just a URL and reads the page in a real browser on our side. Use the extension for quick checks as you browse and the web tool or full Enrichr for the deeper answer.
