This unique  issue  is 100  sign that browser is Safari  believe it or not    if  Object getOwnPropertyDescriptor Document prototype   cookie   descriptor     false       console log  Hello Safari         This means that cookie object descriptor is set to false on Safari while on the all other is true  which is actually giving me a headache on the other project  Happy coding

I know this question is old  but I thought of posting the answer anyway as it may help someone  The above solutions were failing in some edge cases  so we had to implement it in a way that handles iOS  Desktop  and other platforms separately   function isSafari         var ua   window navigator userAgent      var iOS     ua match  iP ad od hone  i       var hasSafariInUa     ua match  Safari i       var noOtherBrowsersInUa    ua match  Chrome CriOS OPiOS mercury FxiOS Firefox i      var result   false      if iOS      detecting Safari in IOS mobile browsers         var webkit     ua match  WebKit i           result   webkit  amp  amp  hasSafariInUa  amp  amp  noOtherBrowsersInUa       else if window safari     undefined     detecting Safari in Desktop Browsers         result   true        else      detecting Safari in other platforms         result   hasSafariInUa  amp  amp  noOtherBrowsersInUa           return result

For the records  the safest way I ve found is to implement the Safari part of the browser-detection code from this answer   const isSafari   window  safari    amp  amp  safari pushNotification  amp  amp      safari pushNotification toString         object SafariRemoteNotification      Of course  the best way of dealing with browser-specific issues is always to do feature-detection  if at all possible  Using a piece of code like the above one is  though  still better than agent string detection

I create a function that return boolean type   export const isSafari        gt  navigator userAgent toLowerCase   indexOf  safari       -1

You can easily use index of Chrome to filter out Chrome   var ua   navigator userAgent toLowerCase     if  ua indexOf  safari      -1       if  ua indexOf  chrome    gt  -1        alert  1      Chrome     else       alert  2      Safari

Because userAgent for chrome and safari are nearly the same it can be easier to look at the vendor of the browser  Safari  navigator vendor      Apple Computer  Inc     Chrome  navigator vendor      Google Inc     FireFox  why is it empty    navigator vendor          IE  why is it undefined    navigator vendor     undefined

I don t know why the OP wanted to detect Safari  but in the rare case you need browser sniffing nowadays it s problably more important to detect the render engine than the name of the browser  For example on iOS all browsers use the Safari Webkit engine  so it s pointless to get  chrome  or  firefox  as browser name if the underlying renderer is in fact Safari Webkit  I haven t tested this code with old browsers but it works with everything fairly recent on Android  iOS  OS X  Windows and Linux    lt script gt      let browserName            if navigator vendor match  google i             browserName    chrome blink             else if navigator vendor match  apple i             browserName    safari webkit             else if navigator userAgent match  firefox   i             browserName    firefox gecko             else if navigator userAgent match  edge   i             browserName    edge edgehtml             else if navigator userAgent match  trident   i             browserName    ie trident             else               browserName   navigator userAgent     n    navigator vendor            alert browserName    lt  script gt    To clarify    All browsers under iOS will be reported as  safari webkit  All browsers under Android but Firefox will be reported as  chrome blink  Chrome  Opera  Blisk  Vivaldi etc  will all be reported as  chrome blink  under Windows  OS X or Linux

Only Safari whitout Chrome   After trying others codes I didn t find any that works with new and old versions of Safari   Finally  I did this code that s working very well for me    x000D   x000D  var ua   navigator userAgent toLowerCase     x000D  var isSafari   false  x000D  try   x000D    isSafari    constructor i test window HTMLElement      function  p    return p toString         object SafariRemoteNotification        window  safari      safari pushNotification   x000D    x000D  catch err     x000D  isSafari    isSafari      ua indexOf  safari      -1  amp  amp     ua indexOf  chrome     -1   amp  amp   ua indexOf  version      -1      x000D   x000D    test x000D  if  isSafari  x000D    x000D      Code for Safari Browser  Desktop and Mobile  x000D    document getElementById  idbody   innerHTML    This is Safari    x000D    x000D  else x000D    x000D    document getElementById  idbody   innerHTML    Not is Safari    x000D    x000D   lt body id  idbody  gt  x000D   lt  body gt  x000D   x000D   x000D

I observed that only one word distinguishes Safari -  Version   So this regex will work perfect      Version  Safari    test navigator userAgent

Modified regex for answer above  var isSafari         chrome android crios fxios    safari i test navigator userAgent      crios - Chrome  fxios - Firefox

Note  always try to detect the specific behavior you re trying to fix  instead of targeting it with isSafari   As a last resort  detect Safari with this regex   var isSafari         chrome android    safari i test navigator userAgent     It uses negative look-arounds and it excludes Chrome  Edge  and all Android browsers that include the Safari name in their user agent

This code is used to detect only safari browser  if  navigator userAgent search  Safari    gt   0  amp  amp  navigator userAgent search  Chrome    lt  0        alert  Browser is Safari

User agent sniffing is really tricky and unreliable  We were trying to detect Safari on iOS with something like  qingu s answer above  it did work pretty well for Safari  Chrome and Firefox  But it falsely detected Opera and Edge as Safari    So we went with feature detection  as it looks like as of today  serviceWorker is only supported in Safari and not in any other browser on iOS  As stated in https   jakearchibald github io isserviceworkerready      Support does not include iOS versions of third-party browsers on that platform  see Safari support     So we did something like  if   serviceWorker  in navigator        return  Safari     else       return  Other Browser       Note  Not tested on Safari on MacOS

Maybe this works    Object prototype toString call window HTMLElement  indexOf  Constructor     EDIT  NO LONGER WORKING

User · Answer

As other people have already noted  feature detection is preferred over checking for a specific browser  One reason is that the user agent string can be altered  Another reason is that the string may change and break your code in newer versions   If you still want to do it and test for any Safari version  I d suggest using this  var isSafari   navigator vendor  amp  amp  navigator vendor indexOf  Apple    gt  -1  amp  amp                 navigator userAgent  amp  amp                 navigator userAgent indexOf  CriOS      -1  amp  amp                 navigator userAgent indexOf  FxiOS      -1    This will work with any version of Safari across all devices  Mac  iPhone  iPod  iPad   Edit  To test in your current browser  https   jsfiddle net j5hgcbm2   Edit 2  Updated according to Chrome docs to detect Chrome on iOS correctly  It s worth noting that all Browsers on iOS are just wrappers for Safari and use the same engine  See bfred it s comment on his own answer in this thread   Edit 3  Updated according to Firefox docs to detect Firefox on iOS correctly

Read many answers and posts and determined the most accurate solution  Tested in Safari  Chrome  Firefox  desktop and iOS versions   First we need to detect Apple vendor and then exclude Chrome and Firefox  for iOS   let isSafari   navigator vendor match  apple i   amp  amp                navigator userAgent match  crios i   amp  amp                navigator userAgent match  fxios i    if  isSafari           else
