Browser Support

The EventSource HQ client library takes care of all cross-browser support issues. Firefox, Chrome, Safari, Opera and Safari Mobile all support EventSource out of the box. For Internet Explorer, Webkit for Android and older browsers EventSource HQ handles all the tricky fallbacks for you. Just send events and we'll get them to your users.


For browsers without EventSource support different fallback methods are used.
