I used to self host TT-RSS (Tiny Tiny RSS) and eventually got tired of maintaining it so I looked for something else. Inoreader is subscription based but I like it the most out of all the ones I’ve tried.
Look here for a comparison of what you get from the free account vs the Pro subscription. https://www.inoreader.com/pricing
It was not difficult but eventually a new version of TT-RSS equired a newer version of php and my provider did not have it nor were they going to upgrade anytime soon. So I looked for a hosted option.
