How to use
User-Agent parser lets you paste a User-Agent string (or use your own) to detect the browser, operating system, engine and device. Enter your value and the parsed details appear instantly, ready to copy.
The calculation runs in your browser, so nothing you enter is sent to a server. It's completely free, with no sign-up, no watermarks and no limits on how often you use it.
Examples
Paste an address or string and the tool breaks it into its component parts for you.
Once user-Agent parser shows your output, use the copy or download button to grab it — no retyping.
