The following is a comparison of RSS feed aggregators. Often e-mail programs and web browsers have the ability to display RSS feeds. They are listed here, too.

Many BitTorrent clients support RSS feeds for broadcatching (see Comparison of BitTorrent clients).

With the rise of Cloud computing, some cloud based services offer feed aggregation. They are listed here as well.
