Tuvix is my attempt at a modern RSS aggregator app that I actually want to use. It looks and behaves like any modern app you expect to see on your phone. It's built as a PWA, so you can use it anywhere.
It has a lot of great extra features, like smart comment link detection, a podcast player that remembers where you left off, and the ability to create public feeds from multiple inbound feed sources.
Cloudflare has a very generous free tier, and RSS doesn't really use all that much compute anyway, so it seemed like a great option for a deployment target and will allow me to run a hosted version for free.
Hope you enjoy!
