❓ Frequently Asked Questions

What is a user-agent string?▸

A user-agent string is an HTTP header sent by browsers to identify themselves. It contains information about the browser, engine, OS, and device, though modern UAs have become increasingly complex.

Why are user-agent strings so long?▸

Browsers include legacy tokens for backward compatibility. Websites historically checked UAs to serve different content. Modern browsers maintain these tokens to avoid breaking older site detection logic.
