PagePeek — Website Change Monitor

Get notified when a web page changes. Dead-simple, no setup, no account. Watch prices, restocks, or any page.

Know the moment a web page changes — without refreshing it yourself. PagePeek watches any web page and alerts you the second it changes: a price drop, a back-in-stock label, a new listing, a status update — anything. WHY PAGEPEEK IS DIFFERENT • Watch one element, not the whole page. Click the exact price or label you care about, and PagePeek ignores everything else — far fewer false alarms than tools that diff the whole page. • Price-drop & threshold alerts. Say "alert me when the number drops below 50" and it pings you only when it crosses. • Keyword alerts. Get notified when a word like "In stock" appears or disappears. • Works on modern JavaScript sites, not just plain HTML. • 100% local & private. No account, no sign-up, no server — your watched pages never leave your browser. • Zero setup. No Docker, no dashboard, no configuration. Install and click. GREAT FOR • Price tracking and price-drop alerts • Back-in-stock notifications • Watching for new job posts, listings, or announcements • Monitoring competitor pages, docs, or status pages • Any "tell me when this changes" need Install, pin it, paste a URL or pick an element — done. Not affiliated with any site you monitor. PagePeek checks pages while your browser is open.
