Been happy with FreshRSS for years now (TTRSS before that). One thing that really improves it is RSS-Bridge which turns a lot of non RSS sites into feeds (and a lot of truncated feeds into full ones). It’s also a list of what hackerly types will put effort into getting a feed from, so self-curating in its way. Enjoy…
Solid. My backup is a T440p, and behind that a X230, fucking bulletproof.
