hello anonymous !



E-Mail is decentralized, so why not instant messaging?
Imagine you could only send E-Mails from your provider to other users using the same provider, that is the stage with most instant messaging applications and we need to break this vendor lock-in.

Extensible Messaging and Presence Protocol (XMPP, originally named Jabber) is an open communication protocol designed for decentralized instant messaging (IM). 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.

Your Jabber Address (jid) is in the format user@server popular and well known due to E-Mail addresses. Just keep in mind that even if your JID looks similar to an E-Mail address it is not compatible and you need to use a dedicated xmpp/jabber client to exchange messages.

End-to-End Encryption

XMPP servers can be isolated (e.g., on a company intranet), and secure authentication (SASL) and point-to-point encryption (TLS). Most modern XMPP Clients support multi-end-to-multi-end encryption (OMEMO) end-to-end encryption between users.
The c0nnect messenger and the c0nnect webapp implement OMEMO and PGP encryption!


The XMPP network architecture is reminiscent of the Simple Mail Transfer Protocol (SMTP), a client–server model. Clients do not talk directly to one another as it is decentralized - anyone can run a server. By design, there is no central authoritative server as there is with messaging services such as AIM, WLM, WhatsApp or Telegram.


A great varity of Clients are available for all major platforms. We have composed a list with some recommendations! For quick access you can always use the free c0nnect xmpp/jabber webapp!


Many server, client, and library implementations are distributed as free and open-source software. Numerous freeware and commercial software implementations also exist.
