This page detects your web browser and its version, your operating system and the browser engine, and shows the full user agent string. It also lists your preferred language, time zone, whether cookies are enabled, touch support, CPU cores, device memory (in Chromium browsers), online status and screen size.

Support teams often ask "which browser and version are you using?". Press Copy report and paste the summary into your email or ticket. All details are read by your own browser; nothing is sent to ToolOrca or anyone else.

What is a user agent?

The user agent is a line of text your browser sends to websites to say what it is, for example which browser, version and operating system. For historical reasons almost every browser's user agent starts with "Mozilla/5.0" and mentions other browsers too, which makes it confusing to read by eye.

Modern Chromium browsers also reduce the detail in the user agent for privacy, for example reporting Windows 10 even on Windows 11. Where the browser offers more precise "client hints", this page uses them.

Why keep your browser up to date?

Browser updates fix security holes that attackers actively use, and add support for new web features. Most browsers update themselves; you can check in the browser's About page (for example Settings → About Chrome).

Frequently asked questions

Why does it say Windows 10 when I have Windows 11?

Browsers freeze the Windows version in the user agent. If your browser supports client hints, the page asks for the exact version; otherwise Windows 10 and 11 look the same.

Why does my browser show as Chrome?

Edge, Opera, Brave, Vivaldi and others are built on Chromium. The page looks for each browser's own marker, but some, like Brave, deliberately identify as Chrome.

Is my information stored?

No. Everything is shown from your own browser and nothing is sent or saved.
