What is a user agent?

A text string your browser sends with every request, describing the browser family, version, and operating system. Sites use it for compatibility — and, combined with other signals, for fingerprinting.

Is this information enough to identify me?

Alone, no — thousands of people share your exact user agent. Combined with screen size, timezone, fonts, and other signals, fingerprinting can get close to unique, which is why privacy browsers try to blend these values.

This tool also lives in the homepage tool drawer alongside 17 others. Browse everything on the tools page or look up any address with the IP lookup.
