About This Tool
### Who is visiting your site?
Every browser sends a "User Agent" string with every request. It looks like gibberish (`Mozilla/5.0 (Windows NT 10.0...)`), but it contains vital info about the user's device.
**User Agent Parser** decodes this string into human-readable data.
### Why parse User Agents?
* **Debugging**: A user reports a bug. You check their UA to see they are on an old version of Safari.
* **Analytics**: Know if your traffic is coming from Mobile vs Desktop.
* **Bot Detection**: Identify if a visitor is a real human or a Google/Bing crawler.
Key Features
- **Instant Detection**: Automatically reads your current browser.
- **Deep Parsing**: Extracts Browser, Engine (Gecko/Blink), OS, and CPU architecture.
- **Bot Identification**: Knows the difference between Chrome and Googlebot.
- **Library Powered**: Built on the robust `ua-parser-js` library.
Frequently Asked Questions
Is this information private?
The User Agent string is standard public information sent with every web request. It does not contain personal identity data, but it can be used for 'fingerprinting'.
Can User Agents be faked?
Yes. It is just a text string header. Developers can easily spoof it to pretend they are a different device (e.g., viewing a mobile site on desktop).
What is 'Gecko' or 'Blink'?
These are Browser Engines. Blink powers Chrome/Edge, Gecko powers Firefox, and WebKit powers Safari. They determine how HTML/CSS is rendered.
