User Agent Parser & Analyzer

User Agent Parser & Analyzer Overview

Extract browser and OS info from a user agent string.

The User-Agent Parser decodes the complex "User-Agent" string sent by web browsers to reveal detailed information about the visitor's device. Every time you visit a website, your browser sends this string containing details about your Browser Name (e.g., Chrome, Safari), Version, Operating System (Windows, macOS, Android), and Device Type (Mobile, Tablet, Desktop). This tool parses that string into a readable format, which is incredibly useful for developers debugging cross-browser issues, analyzing traffic sources, or simply understanding exactly what data their own browser is broadcasting.
