MongooseIM provides a wide range of pluggable and configurable modules, that implement various features including XEPs. For instance mod_muc enables Multi-User Chat (group chat), mod_mam gives us Message Archive Management, and mod_stream_management is for stanza acknowledgement and stream resumption. This modular architecture provides great flexibility for everyday operations and feature development.

A module configuration generally looks like this:

  {mod_muc, [
             {host, "muc.@HOST@"},
             {access, muc},
             {access_create, muc_create}

Module list

Some of the modules feature an iqdisc parameter. It defines the method for handling incoming IQ stanzas. Please refer to [[IQ handlers]] for more information. Valid values: no_queue, one_queue, {queues, N}, parallel. Default: one_queue.


Implements XEP-0050: Ad-Hoc Commands for advertising and executing application-specific commands, such as those related to a configuration workflow, using XEP-0004: Data Forms in order to structure the information exchange. This is extremely useful for use cases such as remote administration, user engagement via polls, and ChatBots.


Implements a subset of XEP-0079: Advanced Message Processing functionality, that enables entities to request, and servers to perform advanced processing of XMPP message stanzas, including reliable data transport, time-sensitive delivery, and expiration of transient messages.


A module used by SASL X-OAUTH mechanism. It provides an API to manage custom OAuth tokens. It requires mod_keystore as an actual key database.


Implements XEP-0191: Blocking Command, a simplified interface to privacy lists.


Allows users to connect to MongooseIM using BOSH (Bidirectional-streams Over Synchronous HTTP), the HTTP long-polling technique described in XEP-0124: Bidirectional-streams Over Synchronous HTTP (BOSH) and XEP-0206: XMPP Over BOSH.


Implements XEP-0115 Entity Capabilities. It queries clients for their supported functionalities and caches them in Mnesia. This module tightly cooperates with mod_pubsub in order to deliver PEP events to user's subscribers.


Implements XEP-0280: Message Carbons in order to keep all IM clients for a user engaged in a real-time conversation by carbon-copying all inbound and outbound messages to all interested resources (Full JIDs).

A framework module to build other notification-based modules on.


Allows sending online/offline notifications, chat and groupchat messages as events to Amazon Simple Notification Service.


Allows sending presence changes (to available/unavailable), chat and groupchat messages as events to a RabbitMQ server.


Implements XEP-0357 Push Notifiactions to provide push notifications to clients that are temporary unavailable.


Forward events to an external HTTP service. This applies to situations such as sending messages or presences to mobile/SMS/email push service, big data, or an analytics service.


Implements XEP-0363: HTTP File Upload for coordinating with an XMPP server to upload files via HTTP and receive URLs that can be shared in messages.


Implements custom inbox XEP


Enables sharing a single XMPP domain between distinct datacenters (experimental).


Enables Jingle to SIP and SIP to Jingle translator.


Serves as a storage for crypto keys for mod_auth_token.


Implements XEP-0012: Last Activity) for communicating information about the last activity associated with an XMPP entity (most recent presence information from an offline contact).


Implements XEP-0313: Message Archive Management, that defines a protocol to query and control an archive of messages stored on a server.


Implements XEP-0045: Multi-User Chat), for a featureful multi-user text chat (group chat), whereby multiple XMPP users can exchange messages in the context of a chat room. It is tightly coupled with user presence in chat rooms.


Provides mod_muc related mongoose_commands, accessible via the client REST API.


Implements a logging subsystem for [mod_muc].


Implements XEP Multi-User Chat Light.


Provides mod_muc_light related mongoose_commands, accessible via client REST API.


Provides an offline messages storage that is compliant with XEP-0160: Best Practices for Handling Offline Messages).


Prevents <service-unavailable/> error when the message recipient is offline.


Implements XEP-0199 XMPP Ping, enabling periodic XMPP pings sent to clients and responds to those sent from clients.


This module implements XEP-0016: Privacy Lists), for enabling or disabling communication with other entities on a network.


Implements XEP-0049 (Private XML Storage) to store and query private user data in XML format.


This extension implements XEP-0060 (Publish-Subscribe). It is a pluggable implementation using behaviours provided by node_*.erl and nodetree_*.erl modules.


Handles push notifications generated by mod_pubsub's node_push and passes them to MongoosePush service.


Implements XEP-0077: In-Band Registration), that enables creating an account and changing the password once connected. This does not provide a solution to the forgotten password use case via SMS or email.


With this extension, MongooseIM may serve as a reverse proxy.
