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.

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

Liferea, in Linux. Simple interface, no fuss, you can split your RSS feeds into folders.

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.

Thunderbird

On Android ReadYou is sooo nice looking. Still missing some features.

I'm using Feeder currently, but I am looking into setting up FreshRSS or Miniflux for easier cross-device use.

I am using Feedbro extension for Firefox to follow a few anime bloggers, Ars Technica and Hackernews.

I use Feedbin as my syncing backend and the excellent Reeder on iPhone and iPad to read the feeds.

I spent so much time trying to find a good reader. Nothing quite scratched that itch I have for google news but less shit. Eventually I came across Artifact. Not an rss reader but it's the best news app I've come across.

After testing many, I stayed with Inoreader on desktop and mobile.

I like the design and the features.

Also, I created a simple userscript for desktop, which automatically loads the full article when I click on one.

Miniflux

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

I use inoreader, and I really enjoy it. I'm an academic researcher, but I don't use RSS feeds for reading papers as what I'm studying is generally very specific.

I use Feedly.

Currently I use Feedly, but if I had the time I’d love to have a CLI aggregator on my Linux box.

FreshRSS on my raspberry pi. I admittedly don't have a super good way to optimize my workflow regarding journals. I added Nature and intended to add more, including more specialized journals for my field, but its feed alone proved to be about as much as I could keep up with. If you're in medical or life sciences, you could try adding feeds based on PubMed searches (there's a "Create RSS" button under the search bar on the results page); you'll get a feed of new papers that match your search terms. I don't know what resources like PubMed there are for other fields and what they might offer in this regard, though.

Nextcloud News

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

I've been a Feedly user ever since Google Reader shut down. For me, the ability to sync feeds and progress among devices is a deal breaker, and I have become pretty partial to the app's swipe to mark as read gesture.

After reading this thread, I may have to give NextCloud News or FreshRSS a try when I'm up for it.

newsboat

Saw this one recommended here yesterday and I'm going to give it a try:

Reeder for iOS, iPadOS, and macOS with Feedly as the backend. Although, Reeder’s local iCloud backend works very well but that’s limited to 1 AppleID.

I am using InoReader.com for backend and @[email protected] for native client front end.

Hi all! I've used many on iOS but always end up with News Explorer. I didn’t know about Thunderbird; I’ll have to look into that for the PC…

photon with maildir2rss

I use the RSS reader in thunderbird, keeps the emails and news in the same place

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

I use Feedbro for Firefox (also available for Chrome). It allows you to filter out items based on their content (supports regex), highlight keywords when viewing items, get desktop notifications for new items in specific feeds, and more.

I use NetNewsWire on my phone and iPad. Slick UI built with iOS standard UI tools, open source, easy to set up and use.

I use Newsboat, it does what I need.

FOSS is king I use NetNewsWire for iOS and it is exactly what I need

Fluent Reader

Ive used newsblur since greader shut down and its worked great for all these years.

Thunderbird; nice and old-fashioned, does everything you want.

RSS Guard
