You can select which files you sync. I have a couple of folders that sync everywhere, and some are only synced on one machine.

I've replaced my nextcloud install with copyparty... Nextcloud went tits up for me after a reboot, the database kept complaining about illegal characters. I have no idea how to solve it, after restoring a backup proved fruitless. So I dropped it. I already had a test instance of copyparty running, I just incorporated the nextcloud data folder to it.
The only thing I miss is the cookbook. But I have the json files, I think I'll cobble together a json interpreter for the files so that I can copy the recipes into some other application.
The only thing from your list that copyparty can't do is keep files offline. It doesn't use a sync-ing client.
There’s opencloud which seems to be exactly what you’re looking for – a files-only lightweight alternative for nextcloud. When I was looking for the post on hacker news I also ran across karadav which seems like it might be a nice hybrid between the DAVs suggested by other users and your existing nextcloud install.
Nextcloud Linux client has an option to selectively sync folders no?
It does in the version I am using
You can access all Nextcloud files over WebDAV. That is natively supported by many file browsers, including explorer.exe on Windows.
And you can choose in the Linux client what folders to sync.
What the Linux client (in contrast to the Windows client) does not support is having virtual files in a folder and only downloading files on demand.
Apart from that, have you looked at Opencloud?
On Windows, Nextcloud seems to tap into some Windows function to provide files on demand. Is there any Linux cloud file service that can do it?
Nextcloud implements webdav, which you can use rclone to mount as a remote.
Also many distros have an online account option which does the same thing
In my experience it's not quite the same. Using webdav through the distro account seems that it's fully online. And folder access or file access contacts the server.
The virtual file experience is more of a hybrid. All the folders actually exist on disk, as well as shells for every file. If you try to open a virtual file, in the background Windows will seamlessly download it for you. At that point the file is actually on your disk. This way regularly accessed files on on your hard drive and seldom accessed ones are not, saving local hard drive space while providing an experience almost like if all the files were actually on your drive.
You could probably do this with FUSE. Guess nobody cared to make that yet.
It exists and I've tried it - https://en.wikipedia.org/wiki/Davfs2
Thing is, when an app thinks a directory is on a local disk, it does things which do not scale well over a network. e.g. reading every file in the directory to make thumbnails.
Seafile has fuse for accessing it as a folder.
What the Linux client (in contrast to the Windows client) does not support is having virtual files in a folder and only downloading files on demand.
This is specifically what I want.
And...somehow I missed opencloud in all of my searching? I think I may have mentally combined it with OwnCloud/OCIS. It looks promising. Diving into the docs, now.
Opencloud is a fork of the new Owncloud, I think. Similar to how Nextcloud was forked from the old Owncloud.
I use Syncthing and Resilio Sync for this stuff.
Both of them sync according to rules you define.
I sync my mobile devices to home this way, and access the folders on the server via SMB shares (which are unrelated to ST or Resilio).
No web interface required, as you just use whatever network sharing you want at home.
What "extra steps" are you running into with SyncThing? Its really flexible (especially Syncthing-Fork for Android). Maybe it or Resilio can be configured to do what you need.
For example,, I use the Selective Sync feature in Resilio so that I can access any file at home whenever I want without using a VPN.
I found that the resilio mobile app would use up a lot of battery at night (sometimes about 10% an hour).
Syncthing was better for that, but would sometimes just stop updating on a phone. I would check and it would have not been syncing for weeks and be signed out of the web UI.
Pretty sure you should have the ability to choose what to sync, either from the server, or the client. Seems kind of dumb for it to automatically assume you have the space on the client device to sync EVERYTHING.
I thought the same thing, but I've spent a good chunk of time looking at every button in the linux client, and it's just options of "sync: y/n", with an initial choice of "do not sync if folder size is 500MB+". And the files/folders not synced do not show up locally. The windows client lets you see everything, but only download when you open or pick "save locally". But not on Linux.
Docs say you can choose what to sync, and disable syncing entirely where you don't want it: https://docs.nextcloud.com/server/latest/user_manual/en/desktop/usage.html
There should be a nearly identical menu to the Windows version that lets you select or deselect folders.
Click on your account > settings. And then it will show the list of folders available to sync.
It's not free but it's awesome and cheap. Setup a WebDAV share and join it using "Mountainduck.io". It connects to everything like SMB but I find WebDAV's multichannel is more performant in the long run. Checks notes Win/Mac only sorry.
I'm searching too. Seafile keeps popping up, but I haven't looked at it yet.
Seafile apparently obfuscates the files, which is not great. If it dies, or they pull some weird shutdown shenanigans, what happens to my files? Nexcloud, at least, is readable and organized, if (in my opinion) weird.
