Got the suggestion from a comment yesterday (I’ll link when I find it) and I’d been using FreshRSS on it’s own for a long time. Morss is a godsend for feeds that like to give you only the headline. It’s also especially awesome for the Hackernews and Lobsters feeds because it will expand the posted links for you which I appreciate a great deal. Hosting it takes like 3 seconds and it’s so worth it.
Miniflux also supports content manipulation https://miniflux.app/features.html#content-manipulation. I use this to download and clean up articles for some feeds. There are also filter and rewrite rules https://miniflux.app/docs/rules.html and a way to rewrite article URLs fetch the original source for paged articles (like on Heise.de) or replace with text-only version (like NPR).
