#FAQ
What is a user agent string? ▾
A user agent string is a text identifier sent by web browsers and other HTTP clients in the User-Agent header. It contains information about the browser name and version, operating system, device type, and rendering engine.
Why are user agent strings so complex? ▾
User agent strings are complex due to historical browser compatibility. Browsers often include identifiers of other browsers to ensure they receive compatible content. For example, most browsers include "Mozilla/5.0" for legacy compatibility reasons.
