How can I find the OS name and OS version using JavaScript?
14 Answers
I started to write a Script to read OS and browser version that can be tested on Fiddle. Feel free to use and extend.
Breaking Change:
Since September 2020 the new Edge gets detected. So 'Microsoft Edge' is the new version based on Chromium and the old Edge is now detected as 'Microsoft Legacy Edge'!

This is perfect! Well written, easy to understand and it collects all the valuable information anyone would need. Thank you for taking the time to post this! – xxstevenxo Oct 13 '13 at 15:53

Brilliant! The only flaw I found is that IE 11 no longer identifies itself as MS IE. I tried to post the fix is a comment here, but it was too long and wouldn't allow it. So I'll post is another response. But otherwise, this was perfect… Thanks so much! – Ian Ippolito Jan 24 '14 at 20:39

1Nice solution, but unfortunately doesn't work correctly for Opera Next (http://en.wikipedia.org/wiki/History_of_the_Opera_web_browser#Version_15). It is detected as Chrome. In order to check for it, get index of 'OPR' in user agent. – Eadel Oct 29 '14 at 08:35
-
Windows Server 2008 is detected as Vista (because it has "Windows NT 6.0"). Full string (for IE7): "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; WOW64; SLCC1; .NET CLR 2.0.50727)". – kolobok Jun 01 '15 at 16:56

2@akapelko Unfortunately Microsoft uses the same version numbers for multiple OS (see https://msdn.microsoft.com/en-us/library/windows/desktop/ms724832(v=vs.85).aspx) – Ludwig Jun 03 '15 at 08:23

Eadel is right... if ( (verOffset = nAgt.indexOf('Opera')) != -1 || (verOffset = nAgt.indexOf('OPR')) != -1 ) { browser = 'Opera'; version = nAgt.substring(verOffset + 4); if ((verOffset = nAgt.indexOf('Version')) != -1) { version = nAgt.substring(verOffset + 8); } } – user2039290 Jul 28 '15 at 13:26

@Ludwig May I suggest adding support for Chrome OS? `{s:'Chrome OS', r:/CrOS/}` - it'll need to go before `{s:'Linux', r:/(Linux|X11)/}`, as the Chrome OS user agent strings may also begin with `X11`... or add a little bit of a more robust check for Linux to ignore `X11` strings that include `CrOS` - `{s:'Linux', r:/(Linux|X11(?!.*CrOS))/}` – skwidbreth Sep 27 '19 at 21:06

2Regarding to number `10` in this line `osVersion = /Mac OS X (10[\.\_\d]+)/.exec(nAgt)[1];`: [next macOS release](https://en.wikipedia.org/wiki/MacOS_Big_Sur) is `11`. So the code should be updated. – Shimon S Sep 15 '20 at 10:35
-
1@ShimonS. Thanks for the note. I've changed the general Mac OS detection. But due of lacking an OS X or OS 11 system, I would be happy if someone could be so kind and test the changes I've made in [Fiddle](http://jsfiddle.net/ChristianL/AVyND/). In addition I added the detection of the new Edge browser (see breaking changes above). – Ludwig Sep 17 '20 at 08:56
If you list all of window.navigator
's properties using
console.log(navigator);
You'll see something like this
# platform = Win32
# appCodeName = Mozilla
# appName = Netscape
# appVersion = 5.0 (Windows; en-US)
# language = en-US
# mimeTypes = [object MimeTypeArray]
# oscpu = Windows NT 5.1
# vendor = Firefox
# vendorSub = 1.0.7
# product = Gecko
# productSub = 20050915
# plugins = [object PluginArray]
# securityPolicy =
# userAgent = Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.12) Gecko/20050915 Firefox/1.0.7
# cookieEnabled = true
# javaEnabled = function javaEnabled() { [native code] }
# taintEnabled = function taintEnabled() { [native code] }
# preference = function preference() { [native code] }
Note that oscpu
attribute gives you the Windows version. Also, you should know that:
'Windows 3.11' => 'Win16',
'Windows 95' => '(Windows 95)|(Win95)|(Windows_95)',
'Windows 98' => '(Windows 98)|(Win98)',
'Windows 2000' => '(Windows NT 5.0)|(Windows 2000)',
'Windows XP' => '(Windows NT 5.1)|(Windows XP)',
'Windows Server 2003' => '(Windows NT 5.2)',
'Windows Vista' => '(Windows NT 6.0)',
'Windows 7' => '(Windows NT 6.1)',
'Windows 8' => '(Windows NT 6.2)|(WOW64)',
'Windows 10' => '(Windows 10.0)|(Windows NT 10.0)',
'Windows NT 4.0' => '(Windows NT 4.0)|(WinNT4.0)|(WinNT)|(Windows NT)',
'Windows ME' => 'Windows ME',
'Open BSD' => 'OpenBSD',
'Sun OS' => 'SunOS',
'Linux' => '(Linux)|(X11)',
'Mac OS' => '(Mac_PowerPC)|(Macintosh)',
'QNX' => 'QNX',
'BeOS' => 'BeOS',
'OS/2' => 'OS/2',

@Ludwig 's solution was brilliant. A couple of fixes (which didn't have to do with operating system, and I couldn't place as a comment on his original posting because this is too long):
- IE 11 no longer identifies itself as MS IE.
- Chrome on IOS spoofs itself as Safari
Here they are:

I've started a github repo based on this. https://github.com/thorst/Browser. Aiming to be minimal, but have enough coverage. – Todd Horst Mar 12 '14 at 14:40

So now all you have to do is keep updating it for every browser on every device as they're released. I don't see "Samsung SmartTV" anywhere. – RobG Oct 20 '15 at 22:26

@Ian Ippolito this is very helpful many thanks. Also i would like to know how can we find the edge browser and its version. – Vijay Nov 29 '17 at 13:06
JavaScript have access to the window.navigator.platform
- a string representing the platform of the browser:
https://developer.mozilla.org/en-US/docs/Web/API/NavigatorID/platform
Use it to extract whatever details you need (and can). Note that there are no guarantees that the client actually uses that platform since this can easily be modified in many ways.

5"This feature has been removed from the Web standards. Though some browsers may still support it, it is in the process of being dropped. Do not use it in old or new projects. Pages or Web apps using it may break at any time." – Con Antonakos Mar 08 '16 at 04:10

1@ConAntonakos can you provide a reference for that statement? That isn't mentioned in the MDN link in this answer. – Splaktar Sep 24 '17 at 06:16
-
4@Splaktar - That's so odd. That messaged was definitely there, but I see it's not anymore. I think at some point in 2016 it was considered? I also see this question (https://stackoverflow.com/questions/38506517/deprecated-javascript-os-detection-techniques), so someone else noticed it as well. Thanks for the update. – Con Antonakos Sep 25 '17 at 17:19

1I think the docs are messed up, it still says it's deprecated in the portuguese version: https://developer.mozilla.org/pt-BR/docs/Web/API/NavigatorID/platform – Gark Garcia Jan 21 '19 at 11:34
-
1UPDATE: I fixed the portuguese docs and I verified that the english docs were indeed corrected at some point. – Gark Garcia Jan 21 '19 at 12:41

1@gark do you work for Mozilla or something or did you hack it? If you hacked it how for you do it? – bluejayke Nov 29 '20 at 20:15
platform.js seems like a good one file library to do this.
Usage example:
// on IE10 x86 platform preview running in IE7 compatibility mode on Windows 7 64 bit edition
platform.name; // 'IE'
platform.version; // '10.0'
platform.layout; // 'Trident'
platform.os; // 'Windows Server 2008 R2 / 7 x64'
platform.description; // 'IE 10.0 x86 (platform preview; running in IE 7 mode) on Windows Server 2008 R2 / 7 x64'
// or on an iPad

You can use this javascript
function to check users' OS simply
function getOS() {
var userAgent = window.navigator.userAgent,
platform = window.navigator.platform,
macosPlatforms = ['Macintosh', 'MacIntel', 'MacPPC', 'Mac68K'],
windowsPlatforms = ['Win32', 'Win64', 'Windows', 'WinCE'],
iosPlatforms = ['iPhone', 'iPad', 'iPod'],
os = null;
if (macosPlatforms.indexOf(platform) !== -1) {
os = 'Mac OS';
} else if (iosPlatforms.indexOf(platform) !== -1) {
os = 'iOS';
} else if (windowsPlatforms.indexOf(platform) !== -1) {
os = 'Windows';
} else if (/Android/.test(userAgent)) {
os = 'Android';
} else if (!os && /Linux/.test(platform)) {
os = 'Linux';
}
return os;
}
alert(getOS());

You can find the OS name and version in the navigator
object, as others have answered. The standard, cross-browser place to find this information is in the navigator.userAgent
property. However, user agent strings vary widely by OS and browser.
So, I created a script to encapsulate this logic and report on the most common OSes and browsers in a familiar way, like http://www.whatsmybrowser.org.
I open-sourced the script and uploaded it to github, https://github.com/keithws/browser-report. Pull requests are welcome!

I fork @Ludwig code and remove necessity of swfobject
.
I just use swfobject code for detect flash version.

I can't comment on @Ian Ippolito answer (because I would have if I had the rep) but according to the document his comment linked, I'm fairly certain you can find the Chrome version for IOS. https://developer.chrome.com/multidevice/user-agent?hl=ja lists the UA as: Mozilla/5.0 (iPhone; CPU iPhone OS 10_3 like Mac OS X) AppleWebKit/602.1.50 (KHTML, like Gecko) CriOS/56.0.2924.75 Mobile/14E5239e Safari/602.1
So this should work:
if ((verOffset = nAgt.indexOf('CriOS')) != -1) {
//Chrome on iPad spoofing Safari...correct it.
browser = 'Chrome';
version = nAgt.substring(verOffset + 6);//should get the criOS ver.
}
Haven't been able to test (otherwise I would have improved his answer) it to make sure since my iPad is at home and I'm at work, but I thought I'd put it out there.

Use detectOS.js:
var Detect = {
init: function () {
this.OS = this.searchString(this.dataOS);
},
searchString: function (data) {
for (var i=0;i<data.length;i++) {
var dataString = data[i].string;
var dataProp = data[i].prop;
if (dataString) {
if (dataString.indexOf(data[i].subString) != -1)
return data[i].identity;
}
else if (dataProp)
return data[i].identity;
}
},
dataOS : [
{
string: navigator.platform,
subString: 'Win',
identity: 'Windows'
},
{
string: navigator.platform,
subString: 'Mac',
identity: 'macOS'
},
{
string: navigator.userAgent,
subString: 'iPhone',
identity: 'iOS'
},
{
string: navigator.userAgent,
subString: 'iPad',
identity: 'iOS'
},
{
string: navigator.userAgent,
subString: 'iPod',
identity: 'iOS'
},
{
string: navigator.userAgent,
subString: 'Android',
identity: 'Android'
},
{
string: navigator.platform,
subString: 'Linux',
identity: 'Linux'
}
]
};
Detect.init();
console.log("We know your OS – it's " + Detect.OS + ". We know everything about you.");

Hey for a quick solution you can consider the following library : UAPARSER - https://www.npmjs.com/package/ua-parser-js
example :
<script type="text/javascript" src="ua-parser.min.js"></script>
<script type="text/javascript">
var parser = new UAParser();
console.log(parser.getOS()) // will log {name: "", version:""}
you can also install the library via npm, and import it like this:
import { UAParser } from 'ua-parser-js';
let parser = new UAParser();
parser.getOS();
the library is a JS based user agent string parser (window.navigator.userAgent is the user agent on browser) , so you can get with it other details aswell such as Browser,device,engines etc..and it can work with node js as well.
if you need typing for the library : https://www.npmjs.com/package/@types/ua-parser-js

I've created a library for parsing User Agent strings called Voodoo. But be aware that this should not be used instead of feature detection.
What Voodoo does, is that it parses the userAgent string, which is found in the Navigator object (window.navigator). It's not all browsers that passes a reliable userAgent string, so even though it's the normal way to do it, the userAgent can not always be trusted.

I loved the Voodoo, but I think should be a way to easily distinguish between mobile, tablet etc... please post it at gittip so I can tip you for the nice job. – lolol May 10 '13 at 21:28
