What Is My Browser? Browser and Device Info

Guide & FAQ

All values are read by scripts in your own browser. This page does not send them anywhere. Sites you visit can read most of the same values, which is why they are sometimes used for fingerprinting.

Guide: What Is My Browser? Browser and Device Info

Check your browser details

The page lists your details the moment it loads, grouped into browser, screen and window, language and time, preferences, input and hardware, network, storage and features, and graphics. Resize the window to watch the viewport size update.

Copy for support or bug reports

Press Copy all as text to put every value on the clipboard as plain text. Attaching it to a bug report saves a lot of back-and-forth, because developers can see the browser version, operating system, screen size and graphics card at once.

What the main values mean

  • User agent: the text a browser sends to identify itself.
  • Viewport: the size of the visible page area, the one that matters for responsive design.
  • Device pixel ratio: how many physical pixels make up one CSS pixel; 2 or more means a high-density display.
  • GPU renderer: the graphics driver the browser uses for WebGL, helpful for diagnosing slow or broken graphics.

Privacy

Websites can read most of these values without asking. This page does not send them anywhere; it only displays them so you know what your browser reveals.

FAQ

What information does this page show?

Your browser's user agent and client hints, platform, screen and window size, device pixel ratio, language and time zone, color and motion preferences, touch support, CPU thread count, storage and cookie availability, WebGL graphics renderer, and network information where the browser provides it.

Is any of this sent to a server?

No. The values are read by scripts in your own browser and shown on the page. Nothing is sent or stored by this tool.

Why do some rows say Not available or Not reported?

Browsers choose what to expose. Firefox and Safari do not provide client hints, device memory or network information, and privacy settings or extensions can hide or randomize other values.

Can websites see this too?

Most of it, yes. Sites can combine details such as screen size, fonts, time zone and GPU into a fingerprint to recognise a browser without cookies. Seeing the values here shows what is exposed.

How can I share this with support?

Press Copy all as text and paste it into your support ticket or bug report. It gives developers the exact browser, device and setting details they usually ask for.
