WebDAV is probably the easiest for syncing the actual articles. I use some standalone server whose name I can’t recall but there’s a bunch of options.
I also use calibre-web for accessing articles through koreader + opds on a Kobo ereader, although this is a manual process and could probably be refined.




Some subsonic clients also support Jellyfin servers, so that could be a useful addition here (although I’m happy with Navidrome myself).
