Feed Sentry 作成者: Scrap Labs

Feed Sentry is for people who follow sites through their feeds. Highlight any link, choose Check for feed from the right-click menu, and it fetches that URL, detects RSS, Atom, or RDF, and tells you the feed type plus how many items it currently lists. No dashboard, no account, no background polling: one fetch, one notification, done. Built by Scrap Labs, the team behind PastAGI, a publication of practical AI guides and honest tool audits.
