Specifications | XMPP - The universal messaging standard
Specifications
The core specifications for XMPP are developed at the

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 using
data.xmpp.net/explore
Good places for developers to start are the
compliance suites
, as well as the
technology overview pages
. For further reading, we suggest the independent
Modern 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.
