User-Agent Client Hints

Chromium browsers expose a few low-detail hints to every page. The detailed hints are read only when you press the button below.

Feature support

Checks only whether each API exists. No permission is requested and no device is accessed. A feature can exist but still be blocked by settings or policy.

How to use this tool

  1. Open the page. The summary at the top shows your Browser, Operating system, Rendering engine, Preferred language, Time zone and whether Cookies enabled is on.
  2. Scroll to Details for the full user agent string, your language list, CPU threads, device memory, touch support, graphics card and privacy settings.
  3. In User-Agent Client Hints, press Show detailed hints if you want the precise platform version, CPU architecture and device model. They are only read when you click.
  4. Check Feature support to see which web APIs your browser offers.
  5. Press Copy as text to copy everything as a plain-text report, for example to paste into a support ticket or bug report.

Everything is read locally by your browser on this page. Nothing is sent to a server or stored.

User agent and Client Hints

The User agent is the text your browser sends with every request to identify itself. It carries a lot of history: almost every browser still starts with “Mozilla/5.0”, and Chrome, Edge and Opera all mention Safari. To reduce fingerprinting, modern browsers also freeze parts of it. Chrome, for instance, reports “Windows NT 10.0” on both Windows 10 and Windows 11, and a fixed macOS version. That’s why the parsed Operating system can be approximate.

User-Agent Client Hints are the newer, structured replacement in Chromium-based browsers (Chrome, Edge, Opera, Samsung Internet and others). A few low-detail hints, Brands, Mobile and Platform, are available to every page. Detailed hints such as Platform version, CPU architecture and Device model must be requested explicitly, and this tool only does so when you press the button. The platform version is what distinguishes Windows 11 (version 13 or later) from Windows 10. Firefox and Safari don’t support Client Hints, so only the user agent string is available there.

The other details

CPU threads (logical cores) is the number of tasks your processor can run at once. Device memory is deliberately rounded and capped by the browser (for example to 0.25, 0.5, 1, 2, 4 or 8 GB) and is only available in Chromium browsers. Max touch points is 0 on most desktops and 5 or 10 on touch screens. Graphics (WebGL renderer) names the GPU used for 3D content, when the browser reveals it. Do Not Track and Global Privacy Control show the privacy signals your browser is set to send.

Feature support

The feature table checks whether each web platform API exists: WebGL and WebGPU for graphics, WebAssembly for fast code, Service Worker for offline apps, WebRTC for video calls, WebAuthn for passkeys, device APIs such as Web Bluetooth and WebUSB, and modern CSS such as container queries, :has() and nesting. It only tests for presence. No permission is asked and no device is accessed. A feature that exists can still be blocked by a setting, an extension or a company policy.

Frequently asked questions

Why is the version number rounded?

Browsers now report only the major version, followed by zeros, in the user agent. Press Show detailed hints in a Chromium browser to see the full version list.

Why does it say Windows 10/11?

The user agent string is identical on both. In Chrome or Edge, Show detailed hints reads the platform version and tells them apart.

Is my browser fingerprinted by this page?

No. The values are displayed only to you, on your screen. Nothing is sent, logged or stored, and the page works the same offline once loaded.

Why is WebGPU or SharedArrayBuffer marked "No"?

WebGPU is still rolling out and needs a supported graphics driver. SharedArrayBuffer is only enabled on pages served with special cross-origin isolation headers, so “No” is expected here.

What should I send to technical support?

Press Copy as text and paste the result. It includes the browser, operating system, user agent and feature support that support teams usually ask for.
