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!
Snikket.org is an xmmp server that bundles common extensions
And has very well working notifications support on iOS with the included app.
