- NetNewsWire: Classical reader for the Apple ecosystem.
- Fraidycat: More novel approach centered around prioritizing different sources (see previous HN discussions [1][2]), available as browser extension or electron application.
- Feedly: Feeds as a service. Free plan limited to 100 sources but very low barrier to entry in my experience for people new to custom feeds. Available via web and mobile apps.
Beware of the "Fanboy's Annoyances List" nuking all indication to the availability of RSS/Atom feeds from websites you visit, if enabled via ad blockers.
