FreshRSS is pretty robust. Been running it on my own server for almost a year with zero issues.

FreshRSS is brilliant. Its ability to fetch full pages, filter CSS elements and utilise session cookies from my browser make it very easy to get a full-text article from most websites I'm interested in. If you're able to spend a little time fine-tuning after you set it up, it can be a very rewarding installation.

As others recommended - freshrss, in a container. Trivial to setup:

If you don't want to run your own service, Innoreader is good.
