Frequently Asked Questions
What can I get from a User-Agent string?
You can infer browser family/version, OS, approximate device class and rendering engine for most common modern clients.
Is User-Agent parsing always accurate?
Not always. UA strings can be spoofed or reduced by privacy settings, so results should be treated as best-effort detection.
Can I use this for analytics debugging?
Yes. It is useful when validating traffic reports, bot patterns, or browser compatibility segments.
