Prosody (formerly lxmppd [2] ) is a cross-platform XMPP server written in Lua. Its development goals include low resource usage, ease of use, and extensibility. Prosody uses the default XMPP ports, 5222 and 5269, for client-to-server and server-to-server communications respectively.
Prosody development was started by Matthew Wild in August 2008 [3] and its first release, 0.1.0, was made in December 2008. [4]
Prosody was initially licensed under the GNU General Public License (version 2), but later switched to the MIT License in its 3rd release. [5]
The XMPP Standards Foundation runs Prosody on xmpp.org, and uses the chatroom feature for meetings for various XSF teams.
Identi.ca the micro-blogging service uses Prosody to deliver IM notifications.
Remember the Milk uses Prosody to deliver IM based reminders.
Collabora runs Prosody on proxies.telepathy.im to provide file transfer proxy lookup for Telepathy (and therefore Empathy).
Peter Saint-Andre [6] (the executive director of the XMPP Standards Foundation) has run Prosody on http://stpeter.im. [7]
In 2023, Jabber.org finished migrating to Prosody. [8]
Pidgin is a free and open-source multi-platform instant messaging client, based on a library named libpurple that has support for many instant messaging protocols, allowing the user to simultaneously log in to various services from a single application, with a single interface for both popular and obsolete protocols, thus avoiding the hassle of having to deal with new software for each device and protocol.
Extensible Messaging and Presence Protocol is an open communication protocol designed for instant messaging (IM), presence information, and contact list maintenance. Based on XML, it enables the near-real-time exchange of structured data between two or more network entities. Designed to be extensible, the protocol offers a multitude of applications beyond traditional IM in the broader realm of message-oriented middleware, including signalling for VoIP, video, file transfer, gaming and other uses.
Adium is a free and open-source instant messaging client for macOS that supports multiple IM networks, including XMPP (Jabber), IRC and more. In the past, it has also supported AIM, ICQ, Windows Live Messenger and Yahoo! Messenger. Adium is written using macOS's Cocoa API, and it is released under the GNU GPL-2.0-or-later and many other licenses for components that are distributed with Adium.
Psi is a free instant messaging client for the XMPP protocol which uses the Qt toolkit. It runs on Linux, Windows, macOS and OS/2.
ejabberd is an Extensible Messaging and Presence Protocol (XMPP) application server and an MQ Telemetry Transport (MQTT) broker, written mainly in the Erlang programming language. It can run under several Unix-like operating systems such as macOS, Linux, FreeBSD, NetBSD, OpenBSD and OpenSolaris. Additionally, ejabberd can run under Microsoft Windows. The name ejabberd stands for Erlang Jabber Daemon and is written in lowercase only, as is common for daemon software.
Jeremie Miller is an American software developer and entrepreneur best known for his role in the development of Jabber and the release of jabberd, an early implementation of an XMPP server, in 1999. His work contributed to the standardization of the Extensible Messaging and Presence Protocol (XMPP) by the Internet Engineering Task Force in 2004, and variations of XMPP have since been implemented on WhatsApp, Kik Messenger, and Zoom.
Google Talk was an instant messaging service that provided both text and voice communication. The instant messaging service was variously referred to colloquially as Gchat, Gtalk, or Gmessage among its users.
The following is a comparison of instant messaging protocols. It contains basic general information about the protocols.
Gajim is an instant messaging client for the XMPP protocol which uses the GTK toolkit. The name Gajim is a recursive acronym for Gajim's a jabber instant messenger. Gajim runs on Linux, BSD, macOS, and Microsoft Windows. Released under the GPL-3.0-only license, Gajim is free software. A 2009 round-up of similar software on Tom's Hardware found version 0.12.1 "the lightest and fastest jabber IM client".
Skype for Business Server is real-time communications server software that provides the infrastructure for enterprise instant messaging, presence, VoIP, ad hoc and structured conferences and PSTN connectivity through a third-party gateway or SIP trunk. These features are available within an organization, between organizations and with external users on the public internet or standard phones.
Jingle is an extension to XMPP which adds peer-to-peer (P2P) session control (signaling) for multimedia interactions such as in Voice over IP (VoIP) or videoconferencing communications. It was designed by Google and the XMPP Standards Foundation. The multimedia streams are delivered using the Real-time Transport Protocol (RTP). If needed, NAT traversal is assisted using Interactive Connectivity Establishment (ICE).
XMPP Standards Foundation (XSF) is the foundation in charge of the standardization of the protocol extensions of XMPP, the open standard of instant messaging and presence of the IETF.
Empathy was an instant messaging (IM) and voice over IP (VoIP) client which supported text, voice, video, file transfers, and inter-application communication over various IM communication protocols.
Jabber.org is a public, free instant messaging (IM) and presence service, based on XMPP, an open standard for IM.
Secure instant messaging is a form of instant messaging. Both terms refer to an informal means for computer users to exchange messages commonly referred to as "chats". Instant messaging can be compared to texting as opposed to making a mobile phone call. In the case of messaging, it is like the short form of emailing. Secure instant messaging is a specialized form of instant messaging that along with other differences, encrypts and decrypts the contents of the messages such that only the actual users can understand them.
Metronome is a light-weight XMPP server written in Lua based on Prosody. It's aimed to provide advanced features while maintaining a modest resource usage. Extensive PubSub and Microblogging over XMPP support along other extensions including: Stream Management, CSI, full support of Bidirectional S2S Streams (BIDI), MAM, Push Notifications, Security Labels, Direct TLS support for C2S/S2S.
Movim is a distributed social network built on top of XMPP, a popular open standards communication protocol. Movim is a free and open source software licensed under the AGPL-3.0-or-later license. It can be accessed using existing XMPP clients and Jabber accounts.
OMEMO is an extension to the Extensible Messaging and Presence Protocol (XMPP) 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 . OMEMO offers future and forward secrecy and deniability with message synchronization and offline delivery.
Xabber is a XMPP client for the Android Operating System. It is developed as an open source Project on GitHub and is licensed under the GNU GPL v.3 license. The original developers are from a software company called Redsolution, Inc. Xabber is available on the Android Play Store and on F-Droid.
Conversations is a free software, instant messaging client application software for Android. It is largely based on recognized open standards such as the Extensible Messaging and Presence Protocol (XMPP) and Transport Layer Security (TLS).
