TT-RSS is fantastic, providing you hold your nose and wear as asbestos suit if you ever dare ask a question or raise a valid issue. The dev is… well, I’m not a fan. I won’t use it out of principle.

FreshRSS is a good-looking and skinnable alternative with a good Docker image, but I had issues with the inability to flush old items. Has a decent web UI.

These days I’m using Sismics and the web UI.
