Used to use FreshRSS. Switched to miniflux and I’m much happier now. It’s very, very simple, very clean, and does exactly what it says on the tin. You may, however, want the less opinionated experience of FreshRSS. You can always try both. (PS. I don’t typically use miniflux as my actual reader – I use reader software for that most of the time, with all my devices pulling from the same miniflux-based RSS source.)
