How to compare RSS readers fairly
A fair RSS reader comparison needs more than a feature checklist. Some products count feeds. Some count sources. Some look generous on feed count but keep only a few hundred items per feed. Others support newsletters, Telegram channels, YouTube, or web pages without RSS, but those extra source types often have separate quotas.
That is why this comparison focuses on five practical questions: how many feeds or sources you can follow, how much history is kept, how often feeds refresh, which non-RSS inputs are supported, and whether the product is open source. Looking at those details makes the tradeoffs much clearer.
People also search for this topic in a few different ways: best RSS reader, best RSS reader app, free RSS reader, open source RSS reader, self-hosted RSS reader, Feedly alternative, Inoreader alternative, or an RSS reader for newsletters, YouTube, or Telegram. This guide is meant to answer those search intents in one place.
Feed caps
The first limit people hit
Free plans often stop at 64, 100, or 150 sources before any other feature matters.
Storage caps
Quietly more important for research
A reader may support many feeds but still keep only 300 to 500 posts per feed.
Extra sources
Usually a separate set of rules
Newsletters, Telegram, YouTube, and web feeds often come with their own quotas.
