What is SimpleX?

The groundbreaking messaging platform distinguishes itself by completely removing the need for user IDs.

In contrast to other services like Signal, Matrix, Session, Briar, Jami, and Cwtch that depend on user identifiers, SimpleX adopts a unique approach by refraining from any user ID or random number usage, thereby significantly improving user privacy.

Curiosity often arises among users regarding how SimpleX successfully delivers messages without these identifiers.

To manage message delivery, SimpleX utilizes temporary anonymous pairwise identifiers specifically for message queues, which are unique to each connection, ensuring that no long-term identifiers are ever used.

Users have the option to choose which server(s) will manage their incoming messages, while their contacts decide the servers to use for sending messages, resulting in each conversation potentially utilizing two distinct servers.

This innovative architecture effectively reduces the chances of metadata leakage on the application level.

Additionally, users can amplify their privacy and protect their IP addresses by routing their connections through Tor when accessing messaging servers.

Only the client devices hold user profiles, contacts, and group information, and messages are protected by a strong two-layer end-to-end encryption system.

This methodology not only emphasizes user privacy but also contributes to an overall more secure messaging environment.

Ultimately, the design choices made by SimpleX reflect a commitment to safeguarding user information in a digital landscape increasingly fraught with privacy concerns.

    SimpleX review

    Date: Dec 14 2023
    Summary

    Good. Useful. Reliable. I'm actually very impressed; I've always looked for an messaging app that would not require phone number or something similar... It seems that I have found it.

    Positive

    Security. Anonymous presence. Encryption. Availability for Windows 64, Android, iOS, and even the terminal.

    Negative

    Not too easy the first time. It may be a little hard to start with it when one is used to playing with another messaging app.
