If you’re curious about FreshRSS please also evaluate miniflux. A fraction of the resource consumption and a better overall experience IMO.

Seconding miniflux, happy user here for ~2 years.

If the web interface is too minimalist/archaic for you, there's plenty of alternative frontends available you can deploy along. Personally, I'm using reminiflux (inspired by Google Reader).

What RSS feeds are people following? Mostly tech stuff?
