Pagepulse

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.
