What is a User Agent?
A User Agent is a text string that a browser sends to a web server in every HTTP request. It tells the server about the browser’s name, version, engine, operating system, and the device you are using.
Servers use user agents to:
- Serve style sheets custom-tailored for mobile vs desktop.
- Gather statistical data on browsers.
- Block bots or scrapers.
Features of this Parser
- Auto-Detect Current User Agent: Instantly detects and parses your current browser’s user agent.
- Custom Input: Paste any custom user agent string to analyze headers from other browsers (e.g. mobile Safari, Googlebot, old IE, Linux Chrome, etc.).
- Comprehensive Details: Extracts the Browser name and version, OS name and version, Layout Engine (WebKit, Gecko, Blink, etc.), Device type (Desktop, Mobile, Tablet, Bot), and CPU details where available.
