Can you please explain why? A quick look at the spec for both protocols shows you that matrix is literally a hundred times more complex, so I don’t understand the basis of the contrary. The matrix creators have shown they are okay with increased complexity under the pretext of a more complete experience, but in reality, XMPP has achieved the same features with far less complexity.
If you’re speaking about self hosting, again, I don’t see how, as matrix is notorious for self hosting issues. XMPP’s snikket works out of the box and has all the commonly used features and plugins pre-baked. The underlying prosody implementation is a step down, but is also quite easy as long as you know what plugins and options to activate (and if you don’t, then use snikket).
I don’t want to defend Matrix. I agree that it is not stable and lightweight. However, I believe it is simpler than XMPP. Wanna set up a server? Synapse. Need a client? Element. The default softwares are easy for new users to discover.
Also, the fact that Matrix has a single protocol means that in theory all servers and clients can work with each other (Although I know we are far from that at the moment). It is much better than XMPP’s XEPs in terms of simplicity.
It’s not that I don’t like XMPP. I want a stable, encrypted, federated messaging platform. However, in terms of money and motivation, Matrix seems to be closer to that right now.
With all due respect, this is a very biased view
Wanna set up a server? Prosody (which has a hassle free out of the box experience through snikket)
Need a client? Conversations
The default softwares are easy to use for new users.
For matrix, however, you are forced to use synapse. You complain that xmpp is not a single protocol, but in reality, all the major implementations are compatible. Can you say the same about matrix? The other implementations aren’t even close to achieving this.
Xmpp’s extensions are a powerful feature, and the issues you think it presents do not exist with xmpp anymore, but is actually the status quo for Matrix.
When I decided to try XMPP, I had to do a lot of research to decide which applications I should use for the server and client. I did not experience this in Matrix. And yes, I know Matrix is not stable. I am not against that. It’s just easier to get on board.
If we told two people to use these two software independently, they would start using Matrix much more faster than XMPP. I think this is enough to call it uncomplicated.
Also, would you recommend Snikket server (or Prosody) for 1:1, group calls and screen sharing?
