Frequently asked questions
The underlying library is updated periodically to recognize new browser releases and mobile device models.

Yes, major versions (like Windows 10 or macOS 13) are reliably extracted from the string.
Major search engine bots (like Googlebot) are flagged, but obscure scrapers might just show as generic curl clients.
It uses common pattern matching; due to widespread spoofing, user-agent parsing should never be treated as 100% authoritative.
