Matrix to XMPP migration
Matrix to XMPP migration

bridge between mattermost, IRC, gitter, xmpp, slack, discord, telegram, rocketchat, twitch, ssh-chat, zulip, whatsapp, keybase, matrix, microsoft teams, nextcloud, mumble, vk and more with REST API...
The Prosody docker images are basically snikket.org which is developed by one of the Prosody developers.
But Ejabberd also has good Docker containers.
Overall I’ve been happy with Matrix (private not federated), but it’s very convoluted. Whenever anything goes wrong it’s really difficult to figure out why, as there is a lot of complexity. And once you set something up, it’s really hard if not impossible to make a change.
For instance, since it’s built for federation, changing the URL is impossible.
So I’d like to try out XMPP since it’s much more lightweight and simple. I may not switch, but want to explore.
perhaps a stupid question, but are there bridges for XMPP ? My impression is that XMPP is as good as empty (I do use it mainly as a federated service). Is there still a lot of development on the XMPP side of things?
I do not understand your point with ‘you cannot change the URL’. If you use matrix as non-federated and just the only user, what is the problem that you need to change the URL when you need to set up a new server on a new URL? Not being able to change the server at the same URL seems like a logical concequence of authentication, be it for server-to-server communication as for client-to-server communication.
Yes they are called “transports”.
As for when I tried to change the URL, I was moving all services from publicly resolvable DNS to .lan, and Matrix is an issue because you can’t change that after the fact, even if you haven’t federated.
HI, Thanks for the info (and also thanks to PoVog).
My experience with mqtt is limited. I once set up a ejabberd server to try it out. It works but -as I mainly interested in federated chat- it was not that interesting. There was a lot less traffic and the rooms that exist that had traffic had a big issue with moderation (i.e. spam content). The S/N ratio of the discussions was a lot less then on matrix or other platforms.
I also notice it was missing some features that are do are present in matrix, like the ability to edit messages. From how I understand it, the modulator nature of XMPP is a nice idea but as there is a large diversity on clients and the features they support, it does seems to come down to only the lowest common domininator to really work well.
As I have just set up a pi5 as my new selfhosting-server, I might give it a try again, and see how well the transports (like slidge as mention by PoVog) work.
Concerning the URL issue, as explained, it kind-of looks like a normal side-effect of the principle of server authentication. Alsom your use-case (one server, one client) it not the normal goal why chat-servers are build. Even in a non-federated use, you have multiple clients connecting to it. Cchanging the server hostname will impact all clients, so is probably a very rare scenario. I did see you use synapse. I do not know if you dendrite or conduit have the same behaviour.
Yes there are gateways (or transports) for xmpp. See for example slidge.im but there are also a few other projects.
It’s maybe a bit less than for Matrix, but the ones that exist tend to work better.
The Signal gateway has currently issues, due to Signald being broken.
For WhatsApp and Discord there is Slidge.
IRC works great with Biboumi.
I am not aware of a Google voice bridge, but there are ways to bridge to the regular phone network and sms. The easiest is the jmp.chat service.
@2xsaiko XMPP is nice and lightweight, so I think either would work fine. I just find prosody has more community momentum.
It was matrix that was a massive memory hog, required running bleeding-edge homeserver software, didn't do proper security support, etc, so that's where I have stronger feelings.
Thanks! I’ll take a closer look at both then and see which I like better.
I am running a Matrix homeserver right now and yeah it’s definitely a mess.
