Font Inspector vs CSS Peeper

The short answer

This is less a head-to-head than a question of scope. CSS Peeper looks at a page the way a designer looks at a mockup: what are the colors, where are the images, what do the buttons look like, what type is in use. Font Inspector looks only at the text, and asks more questions about it.

So the honest answer to “which one?” depends on what you came to the page for. If you want a site’s palette and its SVG icons, Font Inspector cannot help you at all. If you want to know why a headline is rendering in Arial when the CSS says something else, a type-focused tool is the shorter path.

What CSS Peeper does, according to its own pages

We read the Chrome Web Store listing, the official site and its pricing page on September 20, 2026. Here is what they state.

Free core features

• Inspect design properties. Point at an element and click to see its properties, without opening the code.
• Colors. Browse the colors a site uses, check contrast, and export a palette to a design tool.
• Typography. Explore the typography across a site, including font pairings and the most relevant text properties.
• Assets. Browse and download the images, icons and graphics a site uses.

Premium features

• Preview and copy the CSS of any element.
• Browse text styles in use, preview the typography hierarchy, and locate each instance of a text style.
• Browse colors by semantic group such as typography, background and border, and inspect individual color instances, including class and design token.
• Explore gradients color by color.
• A contrast scanner that reports contrast issues across the page.
• Smart Inspector, which adds details such as color contrast, shadows and elevation. The pricing page limits the free plan to three smart inspections a day.
• Sidebar mode, which frees up the page’s viewport.

Pricing, account and version

The pricing page lists three plans: a free plan described as “free forever”, and two paid subscriptions called Professional and Ultra, billed monthly or yearly. Paid plans start with a 7-day trial that asks for a card, and payments run through Stripe. The Chrome Web Store listing confirms that the extension offers in-app purchases. The free plan’s button on the pricing page reads “Sign up for free”. Prices and promotions change, so check the vendor’s pricing page for current numbers.

The listing shows version 1.2.3, with its last update as September 11, 2026. Its privacy section discloses that the extension handles personally identifiable information, authentication information, user activity and website content, and that data is not sold to third parties. The official site links only to the Chrome Web Store. Its FAQ says a subscription is shared between browsers, but does not list them.

Feature comparison

Where a cell says “not mentioned”, the vendor’s pages do not describe the feature. That is not proof it is missing.

When CSS Peeper is the better choice

• You want colors. A full palette of the site, exportable to a design tool, is something Font Inspector does not attempt. It only reports the text color and background color of the text you clicked.
• You want assets. Browsing and exporting a site’s images, icons and SVGs in one place is a big time saver for redesigns and audits. Font Inspector has nothing like it.
• You inspect whole components. Buttons, cards and navigation bars are more than their type. Shadows, elevation, gradients and element CSS belong to a general inspector.
• You audit accessibility across a page. A page-wide contrast scanner finds problems you did not think to click on. Font Inspector checks contrast one text element at a time. Our guide to checking text contrast on a website covers the manual route too.
• You are happy to pay for depth. If a design inspector is a daily tool for you, a subscription for the advanced features can be good value.

When Font Inspector is the better choice

• Type is the question. You get the declared stack, the font actually rendered, and a flag when a fallback is showing. The difference matters more often than you would think, as CSS font stacks and fallbacks explains.
• You need the source of the font. Each family is labeled as Google Fonts, Adobe Fonts, self-hosted or a system font. Get this font then links to the provider, or lists the files of a self-hosted font with a ready @font-face rule. See how to get the font from a website.
• You write Tailwind or SCSS. Copying a style as Tailwind classes or SCSS variables, not only as CSS, is built in and free. More in copy typography as CSS or Tailwind.
• You want a page-wide type audit at no cost. Fonts on this page ranks every family by share of text with weights, sizes and fallback warnings, and outlines where each is used when you hover it.
• You keep a font library. Inspections are saved locally. Compare up to four fonts with the same sample text, and export as JSON, CSS variables or design tokens.
• You want no account and no plan to think about. Everything in Font Inspector is free, and nothing is synced to a server.

How to try both side by side

Because the two overlap only on typography, test them on that, then decide whether you need the rest of what CSS Peeper offers.

1. Install both and refresh the page you want to inspect.
2. Click the same headline and the same paragraph with each tool. Compare what you learn about family, size, weight and line height.
3. Open each tool’s page-wide typography view. Note which details sit behind a paid plan in CSS Peeper and whether you would use them.
4. Copy a style into your editor from each. If you work in Tailwind or SCSS, check how much rewriting each result needs.
5. Now do a non-type task in CSS Peeper: export the palette, or download an icon. If that is part of your week, keep it installed whatever you decide about type.

Keeping both is a reasonable outcome. They answer different questions and do not get in each other’s way. For more options, see the best font identifier extensions compared.
