Matrix works well for me.
It’s not out yet, but I’d keep an eye on Flatline. It’s by the people who make Molly (Signal client fork—it’s pretty good, been using it for years). Flatline is a Molly-compatible server implementation, i.e. so that you can host your own Signal server. Because generally if someone asked for a “reliable messenger for family use” I’d recommend Signal as a polished and reliable option, though not self-hostable unfortunately.
















Pretty sure it’s satire especially with the hashtags.
