I like FreshRSS - I also have some readers that connect to my instance, like FluentReader that provides a better full article view, but I mostly use FreshRSS directly these days.
Looks like it supports a wide range of readers with two different API .
FreshRSS supports access from mobile / native apps for Linux, Android, iOS, Windows and macOS, via two distinct APIs: Google Reader API (best), and Fever API (limited features, less efficient, less safe).
