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.

This module implements support for a Encrypted Push Notifications, a custom extension to XEP-0357: Push Notifications.

Net::PSYC with support for TCP, UDP, Event.pm, IO::Select and Gtk2 event loops. This package includes 12 applications and additional scripts: psycion (a PSYC chat client), remotor (a control console for tor router) and many more.

Telegram-purple is a plugin for Libpurple, the communication library used by the Pidgin instant messaging client, that adds support for the Telegram messenger.

This package is on ``life support'' until tdlib-purple is a full replacement.

This package contains Zulip's official terminal client.

This module implements XEP-0198: when supported by both the client and server, it can allow clients to resume a disconnected session, and prevent message loss.

This library provides a low-level implementation of the IRC protocol for Python. It provides an event-driven IRC client framework with support for the basic IRC protocol, CTCP, and DCC connections.

ngIRCd is a lightweight Internet Relay Chat (IRC) server for small or private networks. It is easy to configure, can cope with dynamic IP addresses, and supports IPv6, SSL-protected connections, as well as PAM for authentication.

This package provides a fork of libsignal-protocol-c, used by Dino to provide OMEMO support.

Pidgin is a modular instant messaging client that supports many popular chat protocols.

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.

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.

libcmatrix is a library for writing Matrix clients in C. It handles transparently end-to-end encryption (E2EE), and stores messages/events in a local database.

Relays messages between different channels from various messaging networks and protocols. So far it supports mattermost, IRC, gitter, xmpp, slack, discord, telegram, rocketchat, twitch, ssh-chat, zulip, whatsapp, keybase, matrix, microsoft teams, nextcloud, mumble, vk and more with REST API. Mattermost is not required.

Nheko want to provide a native desktop app for the Matrix protocol that feels more like a mainstream chat app and less like an IRC client.

Many matrix features are supported, including user registration, rooms, typing notification, emojis, E2E encryption, and voip calls.

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

This is a client library for libsignal-protocol-c. It implements the necessary interfaces using libgcrypt and sqlite.

Python-nbxmpp is a Python library that provides a way for Python applications to use the XMPP network. This library was initially a fork of xmpppy.

Dino is a chat client for the desktop. It focuses on providing a minimal yet reliable Jabber/XMPP experience and having encryption enabled by default.

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.

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 module adds an API for sending and receiving XMPP stanzas.
