How this OS checker works
Your browser shares a small amount of technical information so websites can display correctly. This tool reads those standard signals to identify the operating system, browser and device you are using.
The result is useful when installing software, choosing a download, following setup instructions or giving technical support the details they need.
Common questions
OS detection, explained
How do I find out what operating system I have?
Open this page on the device you want to check. The answer appears automatically at the top, with no settings to hunt through.
Is this OS checker safe?
Yes. It uses standard information already supplied by your browser. It does not need a download, account, camera, location or access to your files.
Why does it say “Windows 10 or 11”?
Modern browsers usually report the same platform identifier for both versions. That privacy-friendly limitation means a normal web page cannot always tell them apart reliably.
Can a browser identify my exact Linux distribution?
Sometimes, but not always. Some browsers include a distribution name while others report only Linux. The result shows the most specific trustworthy answer available.
What is my public IP address?
Your public IP address is the network address that this website sees. It belongs to the internet connection you are using right now, rather than to one specific device.
Does my IP address reveal my exact location?
No. An IP address can sometimes suggest an approximate region or internet provider, but it does not reveal your precise physical address.
Why does my IP address change?
Your public IP can change when you switch networks, restart a router, use mobile data or connect through a VPN. Some internet providers also assign changing addresses over time.
Is my IP address the same as my device address?
Not quite. Your public IP identifies your internet connection to the wider web. Devices inside your home or office network usually have separate private addresses that websites cannot see.
