Questions people ask
User-Agent strings are self-reported by the browser and can be spoofed or customised, so parsing gives a best-effort read rather than a guaranteed-accurate identification.
It's useful for debugging browser-specific bugs from log files, understanding what device a support ticket came from, or checking what a custom User-Agent string in your own app actually reports.
