There seem to be plentiful options for text chat servers, so I’m curious for those that self-host their own, what their preferences & experiences have been with them.
Also those mentioned in the title were just a few examples, if you run something else, e.g. Revolt or Mattermost or something else less popular, would be interested in reading about it!
Do you run it as a mostly isolated/self-contained instance, i.e. not federated/connected to others? I’ve read here & there that for some it seems to bog down as they try to operate it as a federated instance.
