Parse a browser User-Agent string into likely browser, operating system and device class.
Enter the example value or paste your own input, choose the mode when one is available, and read the first result card for the direct answer. The output area gives a copyable block for code reviews, documentation, API tests, classwork or troubleshooting notes.
What the result means
The result uses common token patterns to identify browsers and operating systems for log review and debugging.
What is not included
User-Agent strings can be spoofed and modern browsers reduce detail. Treat the output as a best-effort hint.
Privacy note
The calculation runs in your browser. Avoid pasting production secrets, credentials, private keys, customer data or regulated personal data unless your own policy allows browser-based tools.
