Operating system from the user agent
We detect OS family and version hints (Windows, macOS, iOS, Android, Linux, and others) from the user agent. It is a best-effort parse—not a hardware inventory of your exact build or patch level.
Spoofed UAs, unusual devices, and privacy browsers can change or hide OS tokens.
Hiding or verifying OS details
Some browsers reduce OS granularity in the UA for privacy. For the official name and version, use system settings (About this Mac, Winver, Android/iOS About phone).
A VPN does not change OS detection. Pair with device type and user agent tools for fuller client context.

Frequently Asked Questions
What is an operating system?
An operating system (OS) is the software that runs your device, Windows, macOS, iOS, Android, Linux, and others. We detect OS family and version hints from your browser’s user agent.
Is this exact?
It is a best-effort parse. Browsers sometimes freeze or simplify OS version strings for privacy.
How do we detect the OS?
We read OS family and version hints from the browser’s user agent string. It is best-effort and can be simplified for privacy.
Can I hide my operating system?
Fully hiding it is hard because browsers still send some OS hints. Privacy browsers and fingerprinting resistance can reduce detail, but may break site compatibility.
Does this show my exact Windows or macOS build?
Often only a family or major version. Exact build numbers are frequently omitted from the user agent.
