I'd like to suggest that some people may find wordpress + buddypress + wisechat as a self hosted replacement.

Matrix and some of the connector apps like element / fuzzychat? are nice for self hosted replacement as well.

Yes wordpress has needed securing , which is much easier today than it was 5 years ago.. buddypress can get run over with spam signups, but there are plugins and methods for that.. many ways to handle backups easy and the theming is adaptable, but out of the box familiar enough for most users they can do chats, groups, profiles, etc without ever asking how/where things are.

self hostable, and easy for some, but not as easy to deploy and maintain as clicking a link to join a discord.
