Analyze Your User-Agent | Instant Browser & Device Inspection 🔍
See exactly how your browser identifies itself to websites. Parse any User-Agent (UA) string to instantly extract the OS, browser engine, and hardware details in a clean, developer-friendly format.
🚀 What You Can Do
Every time you visit a site, your browser sends a "handshake" string known as the User-Agent. Use this tool to:
- Verify your browser version to ensure you're running the latest build.
- Debug mobile environments by testing specific UA strings during development.
- Audit your digital fingerprint to see what data your browser reveals.
The analyzer automatically detects your current environment and supports manual input for cross-platform testing.

🧐 FAQ
Does a User-Agent identify me personally? No. A UA string identifies your software and hardware configuration, not your personal identity. However, it is a primary component used in "browser fingerprinting."
Why does my tablet show up as a "Desktop"? Modern tablets (like iPads) now request desktop sites by default. They send desktop-class UA strings to ensure websites serve the full-featured version of the page.
📚 The "Mozilla/5.0" Legacy
Ever wonder why almost every string starts with Mozilla/5.0?
It’s a relic of the 1990s "Browser Wars." When Netscape (Mozilla) was the dominant browser, websites checked for the "Mozilla" string to enable advanced features. To stay compatible, every subsequent browser—from Internet Explorer to Chrome—started claiming "Mozilla-compatibility" to avoid being served broken, stripped-down pages. Today, it remains a permanent fixture of web architecture.
