This feature has been removed from the Web standards. Though some browsers may still support it, it is in the process of being dropped. Avoid using it and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

The NavigatorID.appName property returns the name of the browser. The HTML5 specification also allows any browser to return "Netscape" here, for compatibility reasons.

Note: Do not rely on this property to return the correct browser name. In most browsers (like Firefox, Chrome, Safari, Opera and Internet Explorer) the returned string is "Netscape".


appName = window.navigator.appName 


appName is the name of the browser as a string.


// shows the name of the browser
