Frequently Asked Questions

What is a User-Agent string?

It is a piece of text that your browser sends to every website you visit, telling the server what browser and operating system you are using.

Why do User-Agents look so confusing?

For historical compatibility reasons, most modern browsers pretend to be "Mozilla", and add a long string of other browser names to ensure websites don't block them.

Can User-Agents be faked?

Yes, User-Agent spoofing is very easy. Malicious bots often pretend to be standard Chrome or Googlebot.

Is parsing 100% accurate?

Because strings are messy and constantly changing, parsing is based on heuristic matching. It is highly accurate but not infallible.

Can it identify mobile devices?

Yes, it accurately parses the User-Agent to detect if the device is a phone, tablet, or desktop.

Does it identify the operating system version?

Yes, it extracts the OS name (e.g., Windows, iOS, Android) and its specific version.
