So I want to setup a messaging server in my home that works like Telegram or Whatsapp - it should use the local network as we plan on moving around a lot of photos and files between our devices for some projects

What should I use? XMPP? Or Matrix? Or is there something else that’s ideal for local networks?

Thanks!

    • Mostly it’s because we’re using Telegram for our workflow and everyone is pretty used to it by now (including our parents, who’re slow to adapt).

      We’re gonna be sharing videos, photos, and files on an hourly basis, and not every person is invovled with the every other person’s workflow. If it could ideally be a messenger, we would have conversations regarding these files, and the chat history+notifications on new file upload would be pretty nice.

      • Then it sounds like Matrix is what you want. It can send files just fine and I use it for that all the time.

        You may want to set up some kind of cleanup for media storage, as the files would stay on the server even after being sent and received, otherwise, slowly filling it up.

        If you have a ton of storage and the files are reasonably small, you might be be fine without that, but look into it, at least.

        • Matrix doesn’t really work without a public domain name and so on. Maybe this will change in the future with their p2p experiments, but right now it is not a good suggestion for a local only solution.

                • Matrix has all sorts of hard-coded or at least default configured stuff that needs a internet connection to phone home to the matrix.org servers. The Element web interface will also have issues working due to CORS protection in the browser.

                  Sure it might end up working sufficiently well, but it really isn’t the right tool for this.

                  In general the use of a messenger for this is already less than ideal, but a messenger like matrix that is deeply integrated into a federated network and is build on web technology that isn’t ment to be run locally is just a bad idea, sorry to say.

                  I wouldn’t even recommend XMPP for it, and that is much more self-contained and doesn’t use webtechnology at all.

                  • I don’t recall matrix-synapse needing to talk to any outside systems, unless you federate, generate url previews, or use integrations?

                    And can’t you just self-host element, too? I do.

                    But maybe nextcloud talk, then.

                    And don’t try to guide OP away from what they say they need. Suggest options, fine, but I for one think their decision to try and accommodate existing habits of users, is the correct one.
