Tech News Radar in Your Menu
Only for Mac
Free
Mac
AI-curated tech news in your menu bar. Stories from Hacker News, GitHub Trending, Lobsters, Dev.to & more — filtered, ranked, and summarized. Stay current in seconds.
Sentinel Bar puts the tech news you care about one click away in your macOS menu bar.
Instead of cycling through Hacker News, GitHub Trending, Lobsters, Dev.to, daily.dev, Techmeme, and InfoQ every morning, Sentinel Bar aggregates all seven sources into a single feed — updated every 5 minutes, consumed in seconds.
HOW IT WORKS
Sentinel Bar connects to the Sentinel Feed intelligence platform, which fetches stories from 7 developer news sources every 15 minutes. Stories are deduplicated, ranked by community score, auto-categorized into 6 topic sectors, and optionally enriched with AI-generated summaries.
