Wallabag might be what you're after.

Omnivore looks promising... https://omnivore.app/

Wallabag is great. If you don't want to host, their fee is super low. Like $11/yr or something. That said, I think Omnivore is a better app. But I use Miniflux as my RSS feed reader and it offers super tight integration with Wallabag (and others). Literally click save in Miniflux and it sends it to Wallabag for you. So for now, I'm staying. I did put in a feature request with Miniflux for the same integration level with Omnivore, so maybe in the future?
