Description
Monitor DOM text with CSS selectors, configurable polling intervals, and local change history. Page Monitor watches the webpage text you choose and alerts you when it changes. Track a price, availability message, announcement, or other text without repeatedly checking the page yourself. CHOOSE WHAT TO MONITOR Select a region directly on a webpage, or enter a page URL and CSS selector. Test your selection before saving to confirm you’re watching the right text. CHECK AUTOMATICALLY Choose a checking interval and let Page Monitor check in the background. You can also check immediately, pause monitoring, or edit your monitors from Chrome’s side panel. SEE WHAT CHANGED Receive desktop notifications when selected text changes. Review highlighted before-and-after comparisons, saved snapshots, and the latest 10 changes for each monitor. WORKS WITH DYNAMIC PAGES Page Monitor can read existing open tabs and fetch closed pages. When content requires JavaScript rendering, it warns you before opening a temporary inactive tab to read the page. KEEP YOUR MONITORING DATA LOCAL Monitor settings, selected content, snapshots, and change history stay in your browser. Site access is requested when you select a region or save a monitor. Monitored content is not uploaded to a developer server or payment provider. FREE AND OPTIONAL PAID FEATURES Monitor up to three active regions with checking intervals of five minutes or longer for free, with no account required. An optional lifetime license unlocks more active monitors and shorter checking intervals. Purchase and license restoration are handled through ExtensionPay. Page Monitor requires Chrome 120 or later. Checks run while Chrome is running, and timing may vary when your browser or device is inactive. Some restricted pages cannot be monitored, and desktop notifications depend on browser and operating-system settings.
