Looking at these xmpp servers, ejabberd + a whatsapp bridge seems good to decouple a little bit from the official whatsapp client, thanks for the recommendation!

Vaultwarden seems useful. Going to install it later, thanks!

I’m going to check jellyfin! Thanks

I run my instance using cloudflare tunnels, directly from my thinkpad (over wifi), these tunnels are helpful because you don’t need to open ports, etc, also, there are other tunneling options, like hosting a server on a VPS that tunnels to your own selfhosted server, as there are some alternatives to cloudflare in that aspect.

Idk, might be an option.
