Seafile is probably the next biggest/most developed alternative. When I’ve tried setting it up in the past I’ve had serious issues getting it running behind a reverse proxy. Would be fine for local or VPN/Tailscale style usage though. Also, data is stored in a proprietary database which would make configuring external backups a bit harder.

Syncthing is probably the most flexible option, but it’s not a “cloud” storage solution, it’s peer-to-peer file syncing. Doesn’t really allow for easy selective sync or quick deployment and configuration.

There’s also Owncloud but I don’t have experience with it.

Is it possible to use sub folder domains with duckdns? I’ve only ever used it to point to my dynamic IP and then use my registered TLD with subdomains and cname records pointing to the duckdns address.

Upper Midwest? Milwaukee here, yesterday was awful.
