About What Is My User Agent Free Tool
The user agent string, in the simplest terms, tells the web browser what type of device you are using to browse the internet. The browser then uses this information to display the site in an appropriate way for your device.
The user agent tells us what operating system, browser, and device someone is using. It also tells us how old their operating system and browser are, which is useful for web developers who need to make sure their website works for people on older browsers or devices.
It is compatible with all major browsers and can be used by anyone to find out more about their current web browser.
