Prosody is a modern XMPP communication server. It aims to be easy to set up and configure, and efficient with system resources. Additionally, for developers it aims to be easy to extend and give a flexible system on which to rapidly develop added functionality, or prototype new protocols.

Profanity is a console based XMPP client written in C using ncurses and libmesode, inspired by Irssi.

Pidgin-OTR is a plugin that adds support for OTR to the Pidgin instant messaging client. OTR (Off-the-Record) Messaging allows you to have private conversations over instant messaging by providing: (1) Encryption: No one else can read your instant messages. (2) Authentication: You are assured the correspondent is who you think it is. (3) Deniability: The messages you send do not have digital signatures that are checkable by a third party. Anyone can forge messages after a conversation to make them look like they came from you. However, during a conversation, your correspondent is assured the messages he sees are authentic and unmodified. (4) Perfect forward secrecy: If you lose control of your private keys, no previous conversation is compromised.

uTox is a lightweight Tox client. Tox is a distributed and secure instant messenger with audio and video chat capabilities.

This package provides Zulip's Bot framework.

This module adds an API for sending and receiving XMPP stanzas.

Meanwhile is a library for connecting to a LIM (Lotus Instant Messaging, formerly Lotus Sametime, formerly VPBuddy) community. It uses a protocol based in part off of the IMPP draft(*1), and in part off of traces of TCP sessions from existing clients.

Psi+ is a powerful XMPP client designed for experienced users. It's a spin-off of the Psi XMPP client.

twtxt is a decentralised, minimalist microblogging service for hackers.

So you want to get some thoughts out on the internet in a convenient and slick way while also following the gibberish of others? Instead of signing up at a closed and/or regulated microblogging platform, getting your status updates out with twtxt is as easy as putting them in a publicly accessible text file. The URL pointing to this file is your identity, your account. twtxt then tracks these text files, like a feedreader, and builds your unique timeline out of them, depending on which files you track. The format is simple, human readable, and integrates well with UNIX command line utilities.

This package provides python-pypresence, a Discord RPC client written in Python.

qTox is a Tox client that follows the Tox design guidelines. It provides an easy to use application that allows you to connect with friends and family without anyone else listening in.

This package provides a unique web page for each generated invitation. Without this module, Prosody will only be able to generate invite links as xmpp: URIs (they look something like xmpp:example.com?register;preauth=29Xbxr91). URIs will only work if the invited user already has an XMPP client installed. This is usually not the case.

This module transforms the URI into a friendly web page that can be shared via any method (email, SMS, etc.), and opened in any browser. The page explains the invitation and guides the user to set up their account using one of a configurable list of XMPP clients (to configure the list, see mod_register_apps documentation).

senpai is an IRC client that works best with bouncers.

This module serves common static CSS and Javascript libraries from the filesystem, allowing other HTTP modules to easily reference them.

You can override the filesystem location using the libjs_path configuration option. The default is /usr/share/javascript.

Toxic is a console-based instant messaging client, using c-toxcore and ncurses. It provides audio calls, sound and desktop notifications, and Python scripting support.

HexChat lets you connect to multiple IRC networks at once. The main window shows the list of currently connected networks and their channels, the current conversation and the list of users. It uses colors to differentiate between users and to highlight messages. It checks spelling using available dictionaries. HexChat can be extended with multiple addons.

This package contains Zulip's official terminal client.

Ytalk is a replacement for the BSD talk program. Its main advantage is the ability to communicate with any arbitrary number of users at once. It supports both talk protocols ("talk" and "ntalk") and can communicate with several different talk daemons at the same time.

This module implements XEP-0357: Push Notifications.

Some platforms, notably Apple’s iOS and many versions of Android, impose limits that prevent applications from running or accessing the network in the background. This makes it difficult or impossible for an XMPP application to remain reliably connected to a server to receive messages.

In order for messaging and other apps to receive notifications, the OS vendors run proprietary servers that their OS maintains a permanent connection to in the background. Then they provide APIs to application developers that allow sending notifications to specific devices via those servers.

When you connect to your server with a client that requires push notifications, it will use this module to set up a “push registration”. When you receive a message but your device is not connected to the server, this module will generate a notification and send it to the push gateway operated by your application’s developers). Their gateway will then connect to your device’s OS vendor and ask them to forward the notification to your device. When your device receives the notification, it will display it or wake up the app so it can connect to XMPP and receive any pending messages.

Gajim-OpenPGP is a plugin that adds support for the OpenPGP Encryption to Gajim.

Relays messages between different channels from various messaging networks and protocols.

Purple-Mattermost is a plug-in for Purple, the instant messaging library used by Pidgin and Bitlbee, among others, to access Mattermost servers.

This package implements a web-based registration form that validates invite tokens. It also supports guiding the user through client download and configuration via mod_register_apps.
