PagePulse

Monitor any webpage for content changes. Track prices, text or elements and get notified when something changes. All local.

PagePulse watches webpages for you and sends a notification the moment something changes — no cloud service, no account, no subscription. Set up a monitor in seconds: paste a URL, choose what to watch (full page text, a specific CSS element, page title, or element count), set how often to check, and hit Capture. PagePulse records a snapshot and starts watching. Key Features: 📡 Flexible Watch Modes Monitor the entire page text, a specific element by CSS selector, the page title, the number of matching elements on the page, or a meta tag value. Use the built-in Suggest tool to auto-detect price and stock elements on any product page. ⚡ Instant Change Detection When a monitored page changes, PagePulse highlights exactly what was added and removed with a side-by-side diff view. A notification fires immediately so you never miss an update. 🕐 Flexible Check Intervals Choose how often each monitor checks: every 5 minutes, 15 minutes, 30 minutes, 1 hour, 6 hours, or once daily. Each monitor runs independently. 📋 Full Change History Every detected change is saved with a timestamp, the old and new values, and a diff snippet. Review the full history in the History tab. Clear history any time. 🖱 Right-click to Monitor Right-click any webpage and choose "PagePulse: Watch This Page" to open the add form pre-filled with the page URL and title. 🔒 100% Local All monitoring data, snapshots, and change history are stored locally on your device using chrome.storage.local. No data is transmitted, no account is required.
