Started with RSS recently, and I’ve been using Feeder, but UI wasn’t vibing with me so I wanted to explore other options

One that stood out was Tiny Tiny RSS, but I noticed that it’s self-hosted

Which made me wonder, what are the other feed apps doing? I assumed no back end would be necessary since I can provide the link to the RSS XML

So what kinds of things are the servers doing?

Or am I misinformed and Tiny Tiny RSS is self-hosted because it is doing something beyond the usual feed readers
