User Agent checker
A User Agent Checker is a tool that allows you to detect and analyze the user agent string from a visitor's browser or device. Every time a user accesses a website, their browser sends a "User Agent" string to the server, containing important details about the browser type, version, operating system, and device. Understanding these details is essential for developers, SEO experts, and website owners who wish to tailor their content or detect bots and crawlers.
