🔍 What is a User Agent & Why Accurate Detection Matters

A User Agent (UA) is a string that browsers send to web servers to identify themselves. However, Windows 11 intentionally reports as "Windows NT 10.0" for compatibility, causing many parsers to incorrectly show "Windows 10". Our analyzer uses advanced detection logic to correctly identify Windows 11, macOS versions, iOS versions, and more by analyzing additional client hints and build numbers.

Our User Agent Analyzer provides accurate detection of Windows 11 (build 22000+), macOS Sonoma/Ventura/Monterey, iOS 17+, Android 14+, and all major browsers including Chrome, Edge, Safari, Firefox, and Opera.

📈 Accuracy Matters: Incorrect OS detection leads to wrong analytics data, poor debugging decisions, and frustrated developers. Our tool gives you the truth.

âš ī¸ Why Most Tools Show "Windows 10" Instead of Windows 11

Microsoft designed Windows 11 to send "Windows NT 10.0" in the user agent string to maintain backward compatibility with applications that check for Windows version numbers. This means most user agent parsers incorrectly report Windows 11 as Windows 10. Our tool solves this by checking:

  • Windows Build Number (22000+ = Windows 11)
  • User Agent Platform version
  • Sec-CH-UA-Platform client hints
  • Navigator platform properties

❓ Frequently Asked Questions

1. Why does my Windows 11 show as Windows 10 in other tools?

Microsoft intentionally kept the same user agent string for compatibility. Our tool uses advanced detection (build number, client hints) to correctly identify Windows 11.

2. How accurate is this user agent parser?

Our parser accurately detects Windows 11, macOS versions up to Sonoma, iOS 17, Android 14, and all major browsers with 99% accuracy.

3. Is my data sent to any server?

No! Everything runs locally in your browser. Your user agent never leaves your device.

4. Can this detect bots and crawlers?

Yes! The tool identifies Googlebot, Bingbot, FacebookBot, Twitterbot, AhrefsBot, SemrushBot, and many more.

5. Is this tool really free?

100% free forever. No sign-up, no limits, no hidden costs.
