Fired up a FreshRSS instance for myself when the reddit API notifications came about. Reminds me of my Google Reader days - quite happy with it thus far. Any of the decent quality news sites seem to have an RSS option, at least in my experience so far.
Pretty great on the web browser front-end to be honest - haven’t had an issue when I have used it on my phone. Not sure about the app side of things since I’ve been trying to limit my doom scrolling to when I’m at a computer
