About this tool
Paste a user agent string and the parser breaks it down into browser, operating system, device type, and rendering engine. It also flags known bots and crawlers. Your own browser's UA is auto-detected when you load the page.
This is useful for debugging browser-specific issues, analyzing access logs, or checking what information your browser broadcasts to websites.
Frequently asked questions

Browser name and version, operating system and version, device type (desktop, mobile, tablet), rendering engine, and whether the client is a known bot or crawler.
Does this tool detect my current browser automatically?
Yes. When you load the page, it pre-fills with your browser's user agent string and parses it immediately.
Can it detect bots and crawlers?
It checks for known bot signatures like Googlebot, Bingbot, and other common crawlers. Generic bot patterns are also detected.
