PagePeek
Chrome extension · Free · 100% local · no account

Know the moment a web page changes.

Watch any page for a price drop, a back-in-stock label, or any update — and get pinged the instant it happens. Track just the one element you care about, not the whole page.

Built to be accurate — and private

🎯

Watch one element

Click the exact price or label you care about. PagePeek ignores everything else — far fewer false alarms than tools that diff the whole page.

💰

Price-drop alerts

“Tell me when the number drops below 50.” It reads the price and pings you only when it crosses your target.

📦

Back-in-stock & keywords

Get notified when a word like “In stock” appears — or disappears — on a page.

🌐

Works on modern sites

Handles JavaScript-rendered pages, not just plain HTML.

🔒

100% local & private

No account, no server. Your monitors never leave your browser. Nothing tracked, nothing collected.

Zero setup

No Docker, no dashboard, no configuration. Install, pin, paste a URL — done.
