I recently saw Alex's video about XMPP and I got curious.

I am using Element and Schildichat a bit, trying Element X and curious about the new Development here. It seems vibrant, they rewrite stuff in rust, the Apps are fancy and all.

But I tried Conversations and it seems based too, has transparent encryption, it is damn fast, usable, supports groups and files and all. Probably doesnt use the latest fancy Android SDKs but it seems solid.

I was surprised about how fast it was, as Matrix drastically varies per server. But also I found many dead communities, and in general I dont see XMPP at all, while many Projects (if not using Discord, bruh...) have a Matrix room.

How secure is OMEMO in todays standards? Or OpenPGP, compared to Matrix or Signal Encryption? I heard it also has rotating keys and all.

There are other things, like permission systems, chosen federation, privacy, bridge support and more, that are interesting. Are there advanced modern WebUIs for XMPP you like?

I saw that it uses up waaay less resources, why is that? Really, is "simply encrypted mail" somehow worse in an important way?

Similar to IRC, where I never found nice usable apps for my taste, I thought XMPP was deprecated, but that doesnt seem so?

What can you tell me about XMPP, is it modern, secure, privacy friendly?
