Hi guys do you guys know any selfhosted cloud solution that has a combined sync and filestream option?

Context when you use seafile on macos there is seadrive (mounts external cloud like a drive) and seafile sync which syncs files to local folders. The problem is the two clients sort of act seperatly from one other (you cant make seadrive make files offline for instance neither can you preview files in seafile sync).

By contrast onedrive and google drive both have client apps which can sync on demand (file stream) and optionally make files available offline with a simple right click in context menu.

~~Side note I have tried nextcloud on mac but its experimental mount mode just keeps a placeholder .nextcloud file.~~

Edit:

Nextcloud does have proper virtual file sync. Only limitation is you can't make files availble offline via the context menu and instead need to set up manual folder syncs

Edit 2:

You need to grab the release from https://github.com/nextcloud-releases/desktop/releases/tag/v3.13.0

Specifically the vfs version Nextcloud-3.13.0-macOS-vfs.pkg
