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.
Hi! How much a matrix and mumble server costs?
Well, if you host a server, you can either host it on the cloud (which costs $$$), or you can host it by yourself (if you have a spare computer that you can just use as a server). If you host it yourself, all you’re really paying is the same stuff you already pay — internet and electricity.
Hosting a server for something like mumble, matrix, or lemmy only has the costs I mentioned above.
