Pay for a Feedbin account ($5US a month). It provides the feeds for NetNewsWire on Apple devices and has a decent web interface of its own; it's how I read RSS when I'm not on a Mac or iDevice.

I had been using Miniflux for little less than a year. If you don't want to bother with self-hosting, there's a hosted option.

FreshRSS as a self-hosted server.

NNW for Apple devices and NewsFlash for linux.

I would probably recommend feedly, its okay but not the best

You can use NNW with a Feedly account. Then you can still use the web UI or other clients on non-Mac platforms, and your feeds are kept in sync everywhere.
