The font inspector that actually does something

The Chrome extension that answers "what font is this website using?" in one click — and lets you swap it live, tweak variable axes, find similar typefaces, and export typography to Tailwind, SCSS, or TypeScript tokens.

The quick brown fox jumps over the lazy dog

Hover and click any text. GetFont reads the real rendered font — not just what the CSS declares.

Built for typography work

Six things you'll actually use, every day.

🎯

Inspect with one click

Real rendered font, full CSS readout, source detection (Google / Adobe / @font-face), color swatch — all in one panel rendered in the font itself.

📋

All fonts on a page

One tab away — see every typeface used, grouped, counted, with weights and source. Each card previews the font in itself.

🔄

Live preview, no reload

Swap any font with any other (300+ font autocomplete, free-form input, or instant chips). Iterate as many as you want — the page re-renders in place.

🎚

Variable axes sliders

Drag weight, width, slant, optical size live on the clicked element. Axes the font doesn't support are automatically greyed out.

Frequently asked

Short answers to common questions about GetFont.

Does GetFont identify the real font, or just what's declared in CSS?

The real one. Many sites declare long font stacks like "Helvetica Neue", Arial, sans-serif; GetFont checks which font is actually being rendered for that element via the browser's Font Loading API and shows the one you're really seeing.

Can it find fonts inside images?

Not yet. Recognizing fonts in raster images (the way WhatTheFont does) needs either a hosted backend or an API key. We're evaluating options. For now, GetFont identifies fonts rendered as actual HTML text — which covers virtually all body, heading, and UI typography on the modern web.

Will it slow my browser down?

No. The inspector script is only injected when you click the toolbar icon — there's zero background overhead the rest of the time, unlike older "always-on" font extensions.

How is this different from WhatFont, Fonts Ninja, or Font Finder?

WhatFont is great for quick identification but stops there. Fonts Ninja adds bookmarks and image recognition but requires an account for some features. Font Finder is open source but its UI is developer-focused. GetFont combines the strongest parts of all three and adds what no one else does: variable fonts sliders, live size/weight tweaking on individual elements, and direct export to Tailwind / SCSS / TypeScript tokens — all without an account or any telemetry.

Which browsers work?

Chrome, Brave, Edge, Opera, Vivaldi, and Arc — anything Chromium-based that supports Manifest V3 extensions. A Firefox port is on the roadmap.

Is my data private?

Yes. Nothing leaves your device. No telemetry, no analytics, no account, no servers. Your inspection history (up to 200 recent entries) is stored only in your browser's local storage and can be cleared anytime. The full privacy policy lives in the repository.
