I use NetNewsWire. Since I am happily entrenched in the Apple ecosystem, it works great with its iCloud syncing. This way I can use it on my phone and laptop while not having to set up any server-side infrastructure or rely on a third party to host anything. (Granted I am relying on the iCloud storage for device syncing. But it did not involve any kind of setup and the files are encrypted such that Apple cannot read them.)
