What Version of Safari Do I Have

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.

How to Use This Tool

1. 1

   Open This Page in Safari: Visit this page in the browser you want to check.

2. 2

   Read the Detected Version: Your Safari version, parsed from the user agent string, appears automatically.

How It Works

Safari's user agent includes a `Version/XX.X Safari/XXX.X` pair of tokens, and this tool looks for that pattern in `navigator.userAgent` to read off the version number. It's parsed entirely client-side; nothing about your browser is sent to a server.

Why This Might Be Wrong or Say "Unknown"

Safari has one of the longest-standing histories of deliberately freezing and limiting its user agent's detail for privacy reasons. Apple has done this for years, well before it became a wider trend. That means the version shown here is only as precise as what Safari itself chooses to expose. A wrong or missing result can also happen because: you're not using Safari at all; a different browser is sending Safari-like tokens (`Version/` and `Safari/`) for site compatibility while not actually being Safari; or you're in an in-app browser embedded in a social media app, which on iOS is typically built on Safari's WebKit engine but can still report a modified or generic string.
