Miniflux

Miniflux is an opinionated feed reader: a single Go binary, a deliberately plain interface, keyboard shortcuts, and a refusal to add features that are not reading feeds. It is fast in the way software used to be fast.

It requires PostgreSQL and offers no built-in mobile app, but it speaks common reader APIs so third-party clients work well. Filtering rules and scraping options handle truncated feeds nicely.

For people who think Google Reader was peak internet and want that back with no engagement mechanics attached.
