Monitor any part of a webpage and get alerts when it changes. Track prices, stock and dates. No account needed.

Webpage Change Detector watches the exact part of a webpage you choose and alerts you when it changes. Track prices, stock status, appointment slots, event dates and announcements without refreshing the page yourself. No account and no sign-up. Your monitors and history stay on your device. HOW IT WORKS 1. Open the webpage you want to watch. 2. Select the element to monitor, such as a price, a stock label or a paragraph. 3. Choose how often to check. 4. When it changes, you get a Chrome notification and can see the previous and new content. WHAT YOU CAN MONITOR • Product prices and price drops • Back-in-stock and availability changes • Appointment and booking availability • Event dates and schedule updates • Website announcements and news • Any text or content on a public page FEATURES • Pick a specific element instead of the whole page • See the previous and new content for every change • Chrome desktop notifications • Unread badge on the toolbar icon • Full monitoring history • Custom schedules and check intervals • Manage multiple monitors in one place • Checks run on your schedule while Chrome is running PRIVATE BY DESIGN • No account required • Monitors, snapshots and history are stored locally in your Chrome profile • No developer cloud database, analytics, advertising network or telemetry • Your stored data is never sent to a developer-operated server When a check runs, the extension requests only the webpage you chose to monitor. Cookies for that site may be included so the page loads the way it does in Chrome.
