도구 소개

Decode any User-Agent string into a clean breakdown — browser, engine, OS, device, and version — for log triage, bug reports, and analytics QA.

도구 개요

The User-Agent header is a historical mess: every browser claims to be Mozilla, lots of stacks lie about who they are, and important hints are hidden in trailing tokens. This parser uses a sequence of well-known signatures (in the right order) to identify the real browser and engine, then extracts the OS and the device type. It surfaces the parts that matter — browser, engine, OS, device, raw version — and flags ambiguous strings instead of guessing wildly. Great for triaging support tickets and validating server-side analytics.

사용 사례

자주 묻는 질문

How accurate is the detection?+

For mainstream browsers and operating systems, very accurate. For obscure or spoofed UAs the parser will still surface what it can find and flag the rest as Unknown.

Can it detect bots and crawlers?+

Yes — known crawlers (Googlebot, Bingbot, AhrefsBot, etc.) are recognized and labelled as bots so you can filter them out of analytics.

Is anything sent to a server?+

No. UA parsing happens entirely in your browser; nothing is uploaded.
