Specifications

The core specifications for XMPP are developed at theInternet Engineering Task Force (IETF). The XSF develops extensions to XMPP through a lightweight standards process centered aroundXMPP Extension Protocols (XEPs).

Recently Updated XEPs

The whole list

The XMPP Standards Foundation develops extensions to XMPP in its XEP series. This page lists Stable and Final XEPs as well as experimental proposals that are currently under consideration.

XEP series data can be explored usingdata.xmpp.net/explore.

Good places for developers to start are thecompliance suites, as well as thetechnology overview pages. For further reading, we suggest the independentModern XMPP project which attempts to improve the quality of user-to-user messaging applications that use XMPP.

The following table is sortable, just click on the headers (click twice to reverse the sort order).
You can show/hide the various types of XEPs by applying filters via the Filter button below.

Filter XEPs

Only checked types will be shown
Dormant XEPs in Experimental/Deferred are hidden. Check Dormant to show all Experimental/Deferred XEPs.
