Why is my iPad detected as a Mac?

Since iPadOS 13, Safari on iPad requests desktop sites by default and sends “Macintosh; Intel Mac OS X 10_15_7” with no iPad token in it at all. Nothing in that string can recover the truth; the usual workaround is to test for touch support alongside the header. Where an iPad token is present and the OS reads 13 or later, this parser does label it iPadOS rather than iOS.

What exactly does it accept as input?

The first non-empty line, with a leading “User-Agent:” header name and any surrounding quotes stripped, capped at 4,000 characters. Detection is regex across the whole string, so pasting a full access-log line usually still identifies the browser, the Length row will be counting the entire line rather than the UA.

How it works

User Agent Parser : Browser, Engine, OS and Bot Name

Your own User-Agent is loaded below. Paste any other one, a log line or a copied header value works too, to see the browser, engine, operating system, device and bot signature behind it.

What this does

Thirteen browser families matched in specificity order, so an Edge or Opera string is not read as Chrome
Rendering engine separated from the brand on top of it, Blink, WebKit, Gecko, Trident, EdgeHTML, Presto
Windows NT numbers translated, and the underscore-separated iOS and macOS builds converted to dots
Windows NT 10.0 reported as “10 or 11”, because the string genuinely cannot tell them apart
Forty-eight named crawler and client signatures, Googlebot, GPTBot, curl, Postman, plus a catch-all for anything calling itself a bot
Android WebView identified by its “; wv)” marker instead of being passed off as Chrome
Essentials view of five rows, or Everything for engine version, OS version, CPU and string length

FAQ

User-Agent reduction: Chromium freezes the minor, build and patch numbers at 0.

Not for anything that matters. The header is set by the client, so one curl flag makes a request look like Safari on an iPhone, never use it as a security or licensing check. Browsers have also spent years deliberately reducing what the string carries: Chromium pins macOS at 10.15.7, reports both Windows 10 and Windows 11 as Windows NT 10.0, and zeroes everything after the major version. Treat what you see below as a hint for analytics, and read the User-Agent Client Hints API when you need real values.
