USER_AGENT_FAQ
What is a User-Agent string?
A User-Agent is a text string your browser sends to websites identifying itself. It contains info about your browser name, version, operating system, and sometimes device type.
Why do websites need User-Agent?
Websites use User-Agent to serve appropriate content - mobile sites for phones, compatible code for older browsers, and to gather analytics about their visitors' technology.
Can I change my User-Agent?
Yes. Browser extensions can modify your User-Agent, and developer tools often include this feature. Some privacy browsers randomize User-Agents to reduce tracking.
