Frequently asked questions
It's honest, best-effort pattern matching — modern browsers increasingly freeze or reduce their User-Agent strings for privacy reasons, so treat the result as a helpful guide rather than perfectly authoritative ground truth.
Yes — paste any User-Agent string you have on hand (from documentation, logs, or another source) to see it broken down, without needing to actually use that browser.
It's commonly logged by servers and analytics tools, so understanding what one actually says helps when debugging browser-specific issues or reviewing traffic logs.
Because parsing happens locally, checking a User-Agent string — your own or one you're investigating — never requires sending it to a third-party lookup service.
