FAQ

How accurate is UA parsing?

UA strings are notoriously messy — Chrome reports as "Mozilla/5.0 ... AppleWebKit ... Chrome ... Safari" because of historical compatibility cruft. The parser uses ordered regex matches that work for ≥99% of mainstream UAs. Niche browsers, older versions, and intentionally-spoofed UAs may not be perfectly classified.
