Thanks for your reply! I actually already use both Syncthing and WebDAV. The latter mostly for copying backups and files in between my phone and my server, no bidirectional stuff.

I’ve been periodically checking on your project and look forward to trying it out, it looks great! I’m very impressed by the depth of features and the quality of the information in the README.

I haven’t, but it’s on my list. I also want to try copyparty. Currently, I use SFTPGo, it works pretty well. They both don’t support Nextcloud apps, but I use Round Sync on my phone.
