The User Agent is a text string your browser sends to every site you visit — containing your browser, version, OS and sometimes device. Developers use it to adapt content to your device.
How it works
Your User Agent displays automatically. Copy it for testing, bug reports or configurations.
Use cases
- Web development — test how your site detects browsers and devices

Can you change your User Agent?
