Just wanted to chime in and give a +1 to Anytype. While I haven’t self-hosted the backup node and I can’t help you with that just yet, the fact that a free, P2P decentralized, end-to-end encrypted and source-available notes app like Anytype even exists is awesome!
I’d be curious to see if you manage to get the backup node up and running 👀
Climate Town, is this you??
