How can I find the OS name and OS version using JavaScript?

    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!

    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

    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',
    'Search Bot'=>'(nuhk)|(Googlebot)|(Yammybot)|(Openbot)|(Slurp)|(MSNBot)|(Ask Jeeves/Teoma)|(ia_archiver)'

    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'!

    @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):

    1. IE 11 no longer identifies itself as MS IE.
    2. Chrome on IOS spoofs itself as Safari

    Here they are:

    (function (window) {
        {
        /* test cases
            alert(
                'browserInfo result: OS: ' + browserInfo.os +' '+ browserInfo.osVersion + '\n'+
                    'Browser: ' + browserInfo.browser +' '+ browserInfo.browserVersion + '\n' +
                    'Mobile: ' + browserInfo.mobile + '\n' +
                    'Cookies: ' + browserInfo.cookies + '\n' +
                    'Screen Size: ' + browserInfo.screen
            );
        */

    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
    platform.name; // 'Safari'
    platform.version; // '5.1'
    platform.product; // 'iPad'
    platform.manufacturer; // 'Apple'
    platform.layout; // 'WebKit'
    platform.os; // 'iOS 5.0'
    platform.description; // 'Safari 5.1 on Apple iPad (iOS 5.0)'
    
    // or parsing a given UA string
    var info = platform.parse('Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7.2; en; rv:2.0) Gecko/20100101 Firefox/4.0 Opera 11.52');
    info.name; // 'Opera'
    info.version; // '11.52'
    info.layout; // 'Presto'
    info.os; // 'Mac OS X 10.7.2'
    info.description; // 'Opera 11.52 (identifying as Firefox 4.0) on Mac OS X 10.7.2'
