FAQ

No. The UA can be modified and may be shortened by the browser. The parsing results are clues and should not be used as the only basis for identity authentication, security risk control, or functional support.

Calculation basis and reference materials

Infer the browser, system and device type based on the input User-Agent text and parsing rules. Strings can be modified and browsers can reduce the information in them, so the results are only clues.
