User-Agent Parser

User-Agent Parser Overview

Parse and analyze user agent strings

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.
