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?
Citation needed. Matrix was funded by Amdocs initially, then got investment from Automattic and has gotten some contracts from European Governments, but AFAIK there is no “VC investment” and there certainly aren’t “millions to fund marketing”.
They do have better marketing than any XMPP developer, though. You basically don’t hear anything from process.one or the Prosody devs.
Strait from their blog.
