OS Detection
Instantly detect which operating system and version you're running.
Your operating system (OS) is the software that manages your device's hardware and applications — such as Windows, macOS, Linux, Android, or iOS. Websites detect your OS through the user agent string your browser sends with every request.
Your operating system is the foundation software that runs your device. It manages hardware resources, provides a user interface, and enables applications to run. Each OS has its own characteristics:
Windows: Most popular for desktop PCs, known for wide software compatibility
macOS: Apple's desktop OS, known for design and integration with Apple devices
Linux: Open-source, popular with developers and servers
Android: Most popular mobile OS, runs on many device brands
iOS: Apple's mobile OS, runs exclusively on iPhones and iPads
Need to know which operating system powers your device? Whether for software compatibility, technical support, or system requirements, this free detection tool instantly identifies your OS—Windows, macOS, Linux, Android, iOS, or Chrome OS.
Understanding your system configuration is essential in several scenarios: downloading the correct software version, verifying driver compatibility, meeting game or application requirements, and providing accurate details to support teams. Many software downloads offer different installers for each platform, making OS identification a critical first step.
This tool works by analyzing the user agent string your browser sends to websites. The string contains your platform name and version, though modern browsers may report simplified versions for privacy protection. No files or system settings are accessed—detection happens entirely through your browser.
Each platform has distinct characteristics: Windows offers the widest software library and gaming support; macOS provides seamless Apple ecosystem integration; Linux excels in development and server environments; Android powers most smartphones globally; iOS delivers a secure, curated mobile experience.
Keeping your system updated is vital for security and performance. Updates patch vulnerabilities, fix bugs, and often introduce new features. Whether you're on Windows 11, macOS Sonoma, Android 14, or iOS 17, regular updates protect against emerging threats.

An operating system (OS) is the software that manages your device's hardware and provides services for running applications. Common examples include Windows, macOS, Linux, Android, and iOS.
On Windows, go to Settings > Windows Update. On macOS, go to System Preferences > Software Update. On mobile devices, check Settings > General > Software Update (iOS) or Settings > System > System Update (Android).
For privacy and security, browsers often report simplified or frozen OS version strings. This prevents fingerprinting while still allowing websites to provide compatible experiences.
