Instantly view detailed browser and system information with our free browser diagnostic tool. Check your browser name and version, operating system, CPU cores, device memory, screen resolution, and user agent string. Essential for web development, troubleshooting, and technical support.
Browser information includes details about your web browser, operating system, device hardware, and network connection. This data helps websites optimize content delivery, web developers debug issues, and support teams diagnose problems. Your browser automatically shares this information with websites you visit through the user agent string and JavaScript APIs.
Modern browsers often report a frozen or generic version string (a privacy feature called "user agent reduction"). So seeing "Chrome 120" long after a newer release isn't a bug, it's intentional obfuscation by the browser itself.
