Cove is free and open source, but it is not a drop-in replacement for Momentum. Cove focuses on a local-first new tab, a clean RSS reader, tab triage, and procedural focus audio. Momentum focuses on wallpaper dashboards, widgets, and paid integrations. Choose based on the features you actually use.
Cove is a manual-install Manifest V3 extension that replaces the new tab with a local workspace. Default new tabs vary by browser and may include news, search suggestions, or sponsored content. Check your browser's settings and privacy policy for details.
For reading a curated set of RSS feeds, Cove offers 11 curated sources, custom feed URLs, on-device ranking, and a cache of up to 120 extracted articles. It is not a team or enterprise RSS service and does not provide cloud sync across devices. Feedly or Inoreader may fit those needs better.
If you want a simple clock-and-links page without an RSS reader, tab triage, local ranking, or focus audio, a minimalist start page may be simpler. Cove is for people who want those extra tools in one local-first package.
Cove has no account system, no analytics, no advertising identifiers, and no Cove telemetry endpoint. Settings, notes, reading state, and ranking data stay in browser storage. Network features contact publishers and APIs directly, which necessarily shares normal request data such as your IP address and user agent. See /privacy for the network ledger.
