What this tool does

The user-agent parser turns a raw user-agent string into readable browser, engine, operating-system, mobile, and bot signals.

It helps with debugging browser compatibility, checking crawler traffic, and understanding request logs. User-agent strings can be spoofed, so treat the result as a hint. The user-agent guide explains the limits.
