What is my OS?

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.

It is a best-effort parse. Browsers sometimes freeze or simplify OS version strings for privacy.

We read OS family and version hints from the browser’s user agent string. It is best-effort and can be simplified for privacy.

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.

Often only a family or major version. Exact build numbers are frequently omitted from the user agent.
