- https://en.wikipedia.org/wiki/Talk_(software) - a Unix text chat program, originally allowing messaging only between the users logged on to one multi-user computer—but later extended to allow chat to users on other systems.
Although largely superseded by IRC and other modern systems, it is still included with most Unix-like systems today, including Linux, BSD systems and OS X
- sshtalk - security-minded update to talkd/ntalk with the same basic idea. Modern day instant messaging applications and services are nice and all, but most if not all lack a few key ingredients that we have covered with sshtalk: Hand-written in x86_64 assembly language, Multiple party text user interface, SSH2's native Perfect-Forward-Secrecy, Ephemeral: No archiving of user's messages, Watch (and laugh at) your remote party's typing skills, Full terminal-based Unicode support, Any modern ssh client can use it

- https://en.wikipedia.org/wiki/BITNET_Relay - also known as the Inter Chat Relay Network, was a chat network setup over BITNET nodes. It predated Internet Relay Chat and other online chat systems. The program that made the network possible was called "Relay" and was developed by Jeff Kell of the University of Tennessee at Chattanooga in 1985 using the REXX programming language.
This system drew its name from "relay race" which shares a comparable behavior, where messages travel hop-by-hop along the network of Relay servers until they reached their destination. Messages sent within the United States would take a few seconds to reach their destinations, but communication times varied in other countries or internationally. If one or more network links were down, BITNET would store and forward the messages when the network links recovered, minutes or even hours later.
New old IM
- https://en.wikipedia.org/wiki/OSCAR_protocol - AIM, pre XMPP
- https://en.wikipedia.org/wiki/Client-to-client_protocol - a special type of communication between Internet Relay Chat (IRC) clients. CTCP is a common protocol implemented by most major IRC clients in use today. CTCP extends the original IRC protocol by allowing users to query other clients or channels, this causes all the clients in the channel to reply the CTCP, for specific information. Additionally, CTCP can be used to encode messages that the raw IRC protocol would not allow to be sent over the link, such as messages containing newlines or the byte value 0 (NULL). CTCP does not establish a direct connection between clients; however, it is commonly used to negotiate DCC connections. CTCP allows users to query a remote client about the version of the client they are using (via CTCP VERSION), or the time (via CTCP TIME), among other things. It is also used to implement the /me command (via CTCP ACTION).
- XChat - an IRC chat program for both Linux and Windows. It allows you to join multiple IRC channels (chat rooms) at the same time, talk publicly, private one-on-one conversations etc. Even file transfers are possible. Mostly dead, use HexChat instead.
- Hexchat - an IRC client based on XChat, but unlike XChat it’s completely free for both Windows and Unix-like systems. Since XChat is open source, it’s perfectly legal. For more info, please read the Shareware background. HexChat was originally called XChat-WDK which in turn was a successor of freakschat. For more info, please read the announcement.
- KVIrc - a free portable IRC client based on the excellent Qt GUI toolkit. KVirc is being written by Szymon Stefanek and the KVIrc Development Team with the contribution of many IRC addicted developers around the world.
- Loqui - IRC Client for Gtk2
- Konversation - a user-friendly Internet Relay Chat (IRC) client built on the KDE Platform.
- Smuxi - an open-source, powerful, flexible, and user-friendly chat client created by Mirco Bauer and developed by other contributors. Inspired by the combination of screen and irssi, Smuxi has a detachable server (or like a "normal" client) that stays connected when you aren't, and can allow multiple Smuxi frontends (like the GNOME frontend, or STFL text-based frontend) to be connected and in sync. This is similar to screen+irssi or IRC bouncers, but more elegant and powerful.
- Quassel IRC - a modern, cross-platform, distributed IRC client, meaning that one (or multiple) client(s) can attach to and detach from a central core -- much like the popular combination of screen and a text-based IRC client such as WeeChat, but graphical. In addition to this unique feature, we aim to bring a pleasurable, comfortable chatting experience to all major platforms (including Linux®, Windows®, and MacOS X® as well as Android smartphones), making communication with your peers not only convenient, but also ubiquitous available. 
- https://github.com/magne4000/quassel-webserver - A web server/client for Quassel
- https://github.com/justjanne/quassel-rest-search - a websearch frontend for a quassel database. It offers both a simple HTTP API for search, and a normal website for the same purpose.

- https://github.com/horazont/xmpp-echo-bot - Do you know that situation, you really really need an XMPP echo bot, but you don’t have access to high-level tools like Python to write one? All you have is openssl, bash, dig, stdbuf and sed? Then this tool is for you. This is an XMPP echo bot written in (mostly) sed. Bash is used to do the pre-authentication setup (look up DNS records, establish TLS via openssl s_client). sed processes the XML stream and handles all interaction with the server on the XMPP level. Yes, this kinda parses XML in sed.

- https://prism-break.org/en/protocols/omemo/ - an extension to the Extensible Messaging and Presence Protocol (XMPP/Jabber) for multi-client end-to-end encryption developed by Andreas Straub. According to Straub, OMEMO uses the Double Ratchet Algorithm 'to provide multi-end to multi-end encryption, allowing messages to be synchronized securely across multiple clients, even if some of them are offline'. The name 'OMEMO' is a recursive acronym for 'OMEMO Multi-End Message and Object Encryption'. It is an open standard based on the Double Ratchet Algorithm and the Personal Eventing Protocol (PEP, XEP-0163). OMEMO offers future and forward secrecy and deniability with message synchronization and offline delivery.

- Bitmessage is a P2P communications protocol used to send encrypted messages to another person or to many subscribers. It is decentralized and trustless, meaning that you need-not inherently trust any entities like root certificate authorities. It uses strong authentication which means that the sender of a message cannot be spoofed, and it aims to hide "non-content" data, like the sender and receiver of messages, from passive eavesdroppers like those running warrantless wiretapping programs.
- Pond is forward secure, asynchronous messaging for the discerning. Pond messages are asynchronous, but are not a record; they expire automatically a week after they are received. Pond seeks to prevent leaking traffic information against everyone except a global passive attacker.

- Secure Internet Live Conferencing, or SILC in short, is a modern conferencing protocol which provides rich conferencing features with high security. One of the main design principles of the protocol was security. Many of the SILC features are found in traditional chat protocols such as IRC but many of the SILC features can also be found in Instant Message (IM) style protocols.

- GoldBug is a secure Instant Messenger. You can be sure with using GoldBug (GB), that no third party can look testinto your chat communication. Private user-to-user communication remains private. GoldBug therefore uses strong multi-encryption with different layers of modern encryption technologies of well known and revised crypto libraries (like libgcrypt (GnuPG) and OpenSSL).

The QOTR servers cannot understand what is being said. For chats 256 bit AES-CBC encryption is used. The key generation happens in the browser. To keep it easy to share a chat room, the password is provided as a location hash. Browsers do not send a location hash to the server.
- PDF: Bifrost : A Novel Anonymous Communication System with DHT - An immense amount of information is processed on the Internet due to its spread, increasing the severity of such problems as the disclosure of personal information; privacy protection is required. Research to protect anonymity has become crucial. Anonymous communication systems must consider a sudden breakaway of nodes. However existing systems isn't considering this enough. This paper proposes separating a node management layer from an anonymous communication layer. A novel anonymous communication system is realized by a node management layer that uses Chord, which is a distributed hash table, and the anonymous communication layer uses multiplex encryptions.
