Matrix Messaging

Matrix, sometimes stylized as [matrix], is an open network for secure, decentralized communication. The protocol supports security and replication, maintaining full conversation history, with no single points of control or failure. It supports Instant Messaging with End-to-End Encryption on personal one-to-one chats as well as on group chats and rooms.

There is a big choice of several Matrix Messenger Apps available, and almost every OS and Phone is supported. We can recommend one of the following messengers:

Messenger Logo Website Platforms Pros/Cons
Element Element-Logo Android, iOS, Linux, MacOS, Windows, Web + Stable, widely used
- direct audio recording not (yet) supported
FluffyChat FluffyChat-Logo Android, iOS, Linux, Web + Direct audio recording
- no direct voice calls
SchildiChat SchildiChat-Logo Android, Linux, MacOS, Windows, Web Similar to Element
Chat bubbles
