SimpleX

SimpleX Chat

The first messenger without user IDs. Other apps have user IDs: Signal, Matrix, Session, Briar, Jami, Cwtch, etc. SimpleX does not, not even random numbers. This radically improves your privacy. Many users asked: if SimpleX has no user identifiers, how can it know where to deliver messages? To deliver mesages, instead of user IDs used by all other platforms, SimpleX uses temporary anonymous pairwise identifiers of message queues, separate for each of your connections — there are no long term identifiers. You define which server(s) to use to receive the messages, your contacts — the servers you use to send the messages to them. Every conversation is likely to use two different servers. This design prevents leaking any users' metadata on the application level. To further improve privacy and protect your IP address you can connect to messaging servers via Tor. Only client devices store user profiles, contacts and groups; the messages are sent with 2-layer e2e encryption.

Anonymous Messenger

A peer-to-peer private anonymous and secure messenger that works over Tor. It's also free and open source software which gives users the freedom of changing it and redistributing it under the terms of the GNU General Public License v3. Anonymous Messenger utilizes Tor for its anonymity network and data transport security using the onion v3 protocol and the ability to run onion services on any device and connect directly and anonymously without having to set up any servers, also it uses the signal protocol to encrypt all data before sending it over the Tor network directly to the intended receiver, which means we get two layers of end-to-end encryption without using any server or service. Instead of using HTTP Anonymous Messenger, uses its own transport protocol which is written for anonymity and simplicity. For example, when we send a message we encrypt it using the Signal protocol then we establish an onionV3 encrypted connection and send the encrypted message.
