The best XMPP/Jabber servers for anonymous chat

Jabber/XMPP is a decentralised instant messenger using the open source XMPP protocol, there is no central server that could be compromised, the multiple nodes construct a resilient and hard to monitor infrastructure. Dozens of XMPP servers, encryption and its open source nature make XMPP much harder to wiretap or shut down than cloud based Google Hangouts, Yahoo Messenger or Skype, all USA companies known to have a NSA backdoor.

One of Jabber/XMPP main vulnerabilities is that the server you are connected to is not trustworthy, this is a list of XMPP servers with the best privacy policies:

About Jabber/XMPP security

Any IM client that supports the XMPP protocol can interact with other Jabber users, a few of the best know Jabber compatible clients are Pidgin, Thunderbird and Jitsi, they can be used for videocalls and sending files, but always remember that encryption and end to end  does not mean that your computer IP is hidden. Jabber will help you protect from wiretapping with encryption but the server you use could log what you do and your contact could find out your home IP if you are not on a proxy or VPN.

Another benefit of Jabber is that the same username and password can be used to connect with the social network Jappix, unlike Facebook, you don’t have to provide your real identity to take part in Jappix. Another way to protect your online privacy is running your own Jabber/XMPP server with a custom logs policy, it is not hard to set up an XMPP server with basic understanding of Unix, search for Prosody or Tigase to find XMPP server software to run.

I included XMPP servers with a clear privacy policy of minimum logging or being offshore, those are the claims that the server administrators make, there is no way to verify any of them. If you are social activist RiseUp and Austici provide anonymous Jabber chat servers for people fighting for world change but they are not on the list because they are strictly for political activists.

Sometimes privacy minded individuals set up their own XMPP server and open them to everybody, due to the nature of one man operations, instead of including here privacy servers that have little backing and less chances of long term survival it is best that you check out an updated list of all public XMMP servers at
