User agent parser

User agent parser is a tool that analyzes and interprets the user agent string sent by a web browser or other device. It breaks down the string into its constituent components, such as the browser name, version, operating system, and device type. This information can be used to provide a more tailored experience for users, such as serving different content or layouts based on their device. User agent parsers can also be used to gather data about website traffic, such as the most popular browsers and devices being used to access the site.
