I have used FreshRSS before but I was always annoyed that some sites don’t provide RSS feeds and that even if they provide feeds they don’t provide the whole content through it and only a preview.
What do you recommend for the perfect RSS setup? What are you using? Which app are you using to read them?
I use Miniflux with Reeder on my phone. It has an option to try to extract the full text from sites that only provide a summary but it can be hit or miss in my experience. For sites that don’t offer a feed I know there’s rss-bridge and rsshub, but I haven’t used either to be able to vouch for how well they work.
