What Version of Safari Do I Have
See which Safari version your browser reports, read from your user agent.
Read from your browser's user agent string. Nothing is sent to a server; this is read and shown entirely in your browser.
What is What Version of Safari Do I Have?
Reads the Safari version straight out of your browser's user agent string — a quick check without opening Safari → About Safari on a Mac, or Settings → Safari on an iPhone/iPad. Handy for checking whether a CSS feature or web API you're relying on is supported, or for including a version number in a bug report. Everything runs client-side: the version is parsed from `navigator.userAgent` in your browser and never sent to a server. Safari's version is tied to the OS version it ships with (a given macOS or iOS release bundles a specific Safari build), so this is also a rough proxy for how current the underlying OS is if you can't check that directly.
FAQ
Either you're not using Safari, or your browser sends a generic user agent for privacy, which is increasingly common.
Apple ships Safari as part of the operating system rather than as a separately updatable app (aside from some point releases), so upgrading Safari usually means upgrading macOS or iOS.
No — the version is read from `navigator.userAgent` locally in your browser and never transmitted anywhere.
