What Is My Browser

What Is My Browser tells you which browser you are using, its version, the engine underneath it and the operating system it runs on, in plain words at the top of the page — useful when a help desk asks, when a site says your browser is not supported, or before you report a bug. The details below list the full version, the device type, the processor type and the number of processor threads, roughly how much memory the browser reports, touch points, your languages and time zone, light or dark mode, whether cookies are allowed, whether Global Privacy Control is on, and whether the page is secure. At the bottom is the full user-agent string, with a copy button. Because browsers have frozen parts of that string — Windows 11 still calls itself Windows 10, every Mac claims macOS 10.15.7 — the page also reads the newer client hints where the browser offers them, so it can tell Windows 11 from Windows 10 and give the real macOS version.

1. Open the page: the browser and system appear at the top straight away.
2. Read the list below for details such as the full version number.
3. To send the details to someone helping you, press Copy user agent and paste it into your message.

• Browsers can pretend to be other browsers, and some privacy tools change the user agent on purpose, so this is what your browser says, not proof of what it is.
• Windows 11 and macOS versions come from client hints, which only Chrome, Edge, Opera and other Chromium browsers offer. Firefox and Safari show “Windows 10 or 11” and “macOS”.
• On iPhone and iPad, Chrome, Firefox and Edge all use Apple’s WebKit engine, as Apple requires (outside the EU); the page says so.
• Memory is deliberately rounded by browsers and stops at 8 GB, and only Chromium browsers report it. Processor threads is the number of logical cores, which may be limited by the browser.
• This page does not check whether your browser is up to date; compare the version with the browser’s own About page, which also installs updates.
• Everything here is read by this page from your own browser and shown only to you; nothing is sent, logged or stored. Every website can read the same details — this page only makes them visible to you.

The top of this page shows it. For the exact build, look at the Browser line, or open Chrome’s menu → Help → About Google Chrome, which also checks for updates.

Browsers froze the Windows version in the user agent at “Windows NT 10.0” for both. Chromium browsers report the real version through client hints, which this page reads, so the Operating system line says Windows 11 where it can.

The part of the browser that draws pages and runs their code. Chrome, Edge, Opera and Samsung Internet use Blink; Firefox uses Gecko; Safari uses WebKit. Sites that work in one browser usually work in others on the same engine.

A setting that tells every site you do not want your data sold or shared. Some browsers and extensions turn it on; in some places, laws require sites to respect it.
