Apologies if this question was already asked, I could not find good answer here but maybe I was not using the right keywords.
I would love to host a system for my family (including my grandma who is not very technical) and friends that would let us communicate over messages and audio calls (if video calls would be possible then I would be in 7th heaven)
Can you share what you are using (if you have done something like that)?
Looking through their android app it seems to be similar to google meets, I will definitely keep this in my bookmarks!
(that page also includes a demo deployment)
Appear.in went through some changes (not sure of exactly what) and became "whereby" (sincerely the previous name was so much better).
Another all time favorite of mine (not self-hosted though) is talky.io
And of course there is Jitsi Meet, a very well-known get-a-room application that can also be self-hosted. And they maintain a public deployment too.
