I’ve been using FreshRSS for years, because of it’s flexibility and customization options. I switched to Nextcloud News for a while, since I’m already running Nextcloud anyhow and it’s convenient, but it was far too buggy and missed some quality of life features FreshRSS has.

Also, I use Capy Reader on Android and that app is just perfect, with the same flexibility, plus it lets you read articles in the app, without opening the web page.
