You can use the navigator. appName and navigator. userAgent properties. The userAgent property is more reliable than appName because, for example, Firefox (and some other browsers) may return the string "Netscape" as the value of navigator.
In the browser window, hold the Alt key and press H to bring up the Help menu. Click About Google Chrome and locate the version at the top of the window that appears.
To detect the browser version and browser name, we can use the userAgent in JavaScript.
To check if browser is Google Chrome, try this:
// please note,
// that IE11 now returns undefined again for window.chrome
// and new Opera 30 outputs true for window.chrome
// but needs to check if window.opr is not undefined
// and new IE Edge outputs to true now for window.chrome
// and if not iOS Chrome check
// so use the below updated condition
var isChromium = window.chrome;
var winNav = window.navigator;
var vendorName = winNav.vendor;
var isOpera = typeof window.opr !== "undefined";
var isIEedge = winNav.userAgent.indexOf("Edg") > -1;
var isIOSChrome = winNav.userAgent.match("CriOS");
if (isIOSChrome) {
// is Google Chrome on IOS
} else if(
isChromium !== null &&
typeof isChromium !== "undefined" &&
vendorName === "Google Inc." &&
isOpera === false &&
isIEedge === false
) {
// is Google Chrome
} else {
// not Google Chrome
}

The reason this works is because if you use the Google Chrome inspector and go to the console tab. Type 'window' and press enter. Then you be able to view the DOM properties for the 'window object'. When you collapse the object you can view all the properties, including the 'chrome' property.
You can't use strictly equals true anymore to check in IE for window.chrome
. IE used to return undefined
, now it returns true
. But guess what, IE11 now returns undefined again. IE11 also returns a empty string ""
for window.navigator.vendor
.
I hope this helps!
UPDATE:
Thank you to Halcyon991 for pointing out below, that the new Opera 18+ also outputs to true for window.chrome
. Looks like Opera 18 is based on Chromium 31. So I added a check to make sure the window.navigator.vendor
is: "Google Inc"
and not is "Opera Software ASA"
. Also thanks to Ring and Adrien Be for the heads up about Chrome 33 not returning true anymore... window.chrome
now checks if not null. But play close attention to IE11, I added the check back for undefined
since IE11 now outputs undefined
, like it did when first released.. then after some update builds it outputted to true
.. now recent update build is outputting undefined
again. Microsoft can't make up it's mind!
UPDATE 7/24/2015 - addition for Opera check
Opera 30 was just released. It no longer outputs window.opera
. And also window.chrome
outputs to true in the new Opera 30. So you must check if OPR is in the userAgent. I updated my condition above to account for this new change in Opera 30, since it uses same render engine as Google Chrome.
UPDATE 10/13/2015 - addition for IE check
Added check for IE Edge due to it outputting true
for window.chrome
.. even though IE11 outputs undefined
for window.chrome
. Thanks to artfulhacker for letting us know about this!
UPDATE 2/5/2016 - addition for iOS Chrome check
Added check for iOS Chrome check CriOS
due to it outputting true
for Chrome on iOS. Thanks to xinthose for letting us know about this!
UPDATE 4/18/2018 - change for Opera check
Edited check for Opera, checking window.opr
is not undefined
since now Chrome 66 has OPR
in window.navigator.vendor
. Thanks to Frosty Z and Daniel Wallman for reporting this!
Update: Please see Jonathan's answer for an updated way to handle this. The answer below may still work, but it could likely trigger some false positives in other browsers.
var isChrome = /Chrome/.test(navigator.userAgent) && /Google Inc/.test(navigator.vendor);
However, as mentioned User Agents can be spoofed so it is always best to use feature-detection (e.g. Modernizer) when handling these issues, as other answers mention.
even shorter: var is_chrome = /chrome/i.test( navigator.userAgent );
If you want to detect Chrome's rendering engine (so not specific features in Google Chrome or Chromium), a simple option is:
var isChrome = !!window.chrome;
NOTE: this also returns true
for many versions of Edge, Opera, etc that are based on Chrome (thanks @Carrm for pointing this out). Avoiding that is an ongoing battle (see window.opr
below) so you should ask yourself if you're trying to detect the rendering engine (used by almost all major modern browsers in 2020) or some other Chrome (or Chromium?) -specific feature.
And you can probably skip !!
console.log(JSON.stringify({
isAndroid: /Android/.test(navigator.userAgent),
isCordova: !!window.cordova,
isEdge: /Edge/.test(navigator.userAgent),
isFirefox: /Firefox/.test(navigator.userAgent),
isChrome: /Google Inc/.test(navigator.vendor),
isChromeIOS: /CriOS/.test(navigator.userAgent),
isChromiumBased: !!window.chrome && !/Edge/.test(navigator.userAgent),
isIE: /Trident/.test(navigator.userAgent),
isIOS: /(iPhone|iPad|iPod)/.test(navigator.platform),
isOpera: /OPR/.test(navigator.userAgent),
isSafari: /Safari/.test(navigator.userAgent) && !/Chrome/.test(navigator.userAgent),
isTouchScreen: ('ontouchstart' in window) || window.DocumentTouch && document instanceof DocumentTouch,
isWebComponentsSupported: 'registerElement' in document && 'import' in document.createElement('link') && 'content' in document.createElement('template')
}, null, ' '));
var is_chrome = /chrome/.test( navigator.userAgent.toLowerCase() );
As of Chrome 89 (March 2021), all earlier answers are obsolete. Chrome now supports User Agent Hints. So now this should be done using:
navigator.userAgentData?.brands?.some(b => b.brand === 'Google Chrome')
Or, if you're not using Babel:
navigator.userAgentData && navigator.userAgentData.brands && navigator.userAgentData.brands.some(b => b.brand === 'Google Chrome')
This returns true for Chrome 89 and above, false for the latest Opera and Edge, and undefined for browsers that don't support userAgentData.
