Open source alternatives to Matter[007]

Matter is a reading app that gathers articles and newsletters into one queue with highlights, notes and text-to-speech. Below are 7 self-hostable open source alternatives, ranked by GitHub popularity.

// EDITOR'S TAKE

Wallabag comes closest to Matter's core loop of saving long reads and rendering them cleanly, though nothing here replicates the audio playback or newsletter inbox. Karakeep adds AI tagging and search that make a large backlog navigable, and Linkwarden is the better choice if permanent archiving matters more to you than the reading experience.
