I’m working on a project that needs a similar approach to slack or discord. I know about matrix, but the person I’m working with said to be open to use a fediverse alternate when I tell them I didn’t want to use slack. I mention matrix and the fediverse as an alternative and they asked me a good fediverse option.
It’s needs to be good for team collaboration, easy to set and be able to maintain original images quality.
Currently hosting XMPP:
As for encryption and feature support, YMMV, https://providers.xmpp.net/ has a list of servers that provide everything.
Thanks!!
Do you have, or have you seen, any use of XMPP groups for IRC/Matrix/Discord/Slack like cases? Large, persistent groups that anyone can join without invite (with just an address eg on a web page)?
