What self-hosted sync approach are you using?

I’m thinking of doing the same thing, as I want everything on my home NAS and not iCloud/Google Drive

I setup the LiveSync plugin in an LXC on one of my proxmox servers, since I was going to have to host the MCP server too (so Claude could read from it).

It doesn't require iCloud/GDrive, I just exposed the corresponding port through a cloudflare tunnel and set up the apps to connect through it.
