About Matrix Matrix is an open protocol for decentralised, secure communications.
Matrix Manifesto We believe:
People should have full control over their own communication. People should not be locked into centralised communication silos, but instead be free to pick who they choose to host their communication without limiting who they can reach. The ability to converse securely and privately is a basic human right. Communication should be available to everyone as a free and open, unencumbered, standard and global network.
For matrix it depends on how big rooms you join, the way matrix federates the more servers in a room the more resources it’ll take to join it and send messages in it since you send a message to every server in a room, conduit is a much more efficient homeserver implementation compared to synapse
