I’m looking into hosting one of these for the first time. From my limited research, XMPP seems to win in every way, which makes me think I must be missing something. Matrix is almost always mentioned as the de-facto standard, but I rarely saw arguments why it is better than XMPP?
Xmpp seems way easier to host, requiring less resources, has many more options for clients, and is simpler and thus easier to manage and reason about when something goes wrong.
So what’s the deal?
Suggest your friend to give Eturnal a try maybe. I have it running on an Oracle free tier instance, and I use it daily to have video calls with my family using Synapse/Element (and Jitsi inside Element for group calls), and it works great. The documentation is very good too.
Edit: this is my Eturnal config, for reference:
eturnal: listen: - ip: "::" port: 3478 transport: udp enable_turn: true - ip: "::" port: 3478 transport: auto enable_turn: true - ip: "::" port: 5349 transport: tls enable_turn: true realm: turn.<MY_DOMAIN> tls_crt_file: /etc/letsencrypt/live/turn.<MY_DOMAIN>/fullchain.pem tls_key_file: /etc/letsencrypt/live/turn.<MY_DOMAIN>/privkey.pem tls_options: - no_tlsv1 - no_tlsv1_1 - cipher_server_preference
And the compose file:
