When GReader died, I switched to Feedly for a bit, but then found InoReader and have stuck with them since. It’s got the most options for customization/organization and filters/rules that I need and the Android app is great.

Thunderbird

I use Newsboat, it does what I need.

I used to use Thunderbird, but switched to Nextcloud News to make it work across multiple devices

I use Reeder 5. It’s nice, no complaints.

Nextcloud News

Does well enough and I use Nextcloud for various other things already.
So no real reason to use anything else.

I use Elfeed for Emacs, as just one small part of Emacs’s slow conquest of other programs on my computer. Before that, I used Liferea, which is a nice standalone feed reader.

Elfeed lets me assign each feed in my list different tags, so I can do basic filtering for what I want to read at any given time. I generally avoid subscribing to any high-density feeds like news sites. I prefer to have maybe a dozen or so links per day that definitely interest me.

I use morss.it to fetch the full text from feeds that only provide a brief summary.

I self-host FreshRSS. I’m pretty happy with it. It works well and you can add extensions to customize it if you need something particular. And I use the browser extension so I get notifications for new articles.

I used to use Feedly before. It was pretty alright, but I got annoyed by just how many things you needed to pay for
