Comparing #XMPP against #email protocols is too limited. What sets #deltachat apart is *vertical integration* and being driven by UI/UX considerations. Cross-platform Apps and Bots use the Rust core library which connects with #chatmail relays and classic email servers based on a higher level API -- abstracting over SMTP, MIME, #OpenPGP etc. See chatmail.at

#webxdc apps in turn use an even higher level stable API abstracting over email/xmpp/... see webxdc.org/docs/

That's a very illuminative post!

In other words, please CMIIW:

#XMPP is an open protocol standard with various independent implementations in many programming languages for most operating systems. Almost not two #Jabber clients use the same library.

Delta Chat, OTOH, is a single vendor software framework based on various open standards. My guess: Independent implementations are possible, but maybe not encouraged, because they would sooner or later diverge too much from the original?

@debacle that's about right! As to servers/relays: there are a lot of well working alternative stacks -- #chatmail core even runs with some #Plan9 mail server stack apart from the many classic email server implementations. Replacing Rust Core is possible but considerable work. Beating its maturity and cross-platform portability would require a serious effort. Not impossible, though. FWIW most other messenger projects (#Signal, #matrix, etc.) are trying to move towards Rust.

And here is the typical #Jabber situation: There are at least TWO #Rust #XMPP libraries! 😞

#XMPPrs: xmpp.rs/ (#MPL)

#luz: bunny.garden/luz/ (#AGPL)

Maybe more.

None of them in #Debian yet, i.e. I see a lot of work ahead 😞
