NewsBlur
The core loop is small enough for a capable coding agent to produce a useful local version. For NewsBlur, self-host a feed reader with training filters, folders, and full-text search. The hard boundary is hosted convenience, native apps, story intelligence, and community features, plus capture polish, sync, and content partnerships.

Pinboard
The core loop is small enough for a capable coding agent to produce a useful local version. For Pinboard, run a fast private bookmark archive with tags, notes, and full-text search. The hard boundary is hosted longevity, simple api, archive service, and zero-maintenance reliability, plus capture polish, sync, and content partnerships.
Build it
Reeder
The core loop is small enough for a capable coding agent to produce a useful local version. For Reeder, build a native feed and read-later client with local search and sync through a chosen account. The hard boundary is native apple polish, broad account support, gestures, and long-term maintenance, plus capture polish, sync, and content partnerships.
