Web Page Change Monitor & Visual Diff

About

Web Page Change Monitor & Visual Diff helps you track updates on web pages without manually checking them again and again.

Select a specific area of a page, or monitor the full page, and the extension will save a local text snapshot. When you return to that page, it checks the latest visible content and tells you if something has changed.

It is useful for monitoring:

• Public tenders and official notices
• Job postings and career pages
• Real estate listings
• Product availability and price changes
• News sections and articles
• Booking pages and waiting lists
• Any web page where important information may be updated

The extension is designed to be simple:

1. Open a web page
2. Open the extension sidebar
3. Choose “Select area to monitor” or “Monitor full page”
4. Return later and see if anything changed
5. Open the visual diff to compare the saved text with the latest detected text

Main features:

• Monitor selected parts of web pages
• Monitor entire pages
• Automatic check when you revisit a monitored page
• Live monitoring while the page is open in a browser tab
• Visual text diff to quickly see what changed
• Local snapshots stored on your device
• Dashboard with all monitored pages
• Import and export your monitors
• Multilingual interface
• No account required

For selected areas, the extension focuses on clean visible text instead of screenshots or raw HTML. This helps reduce false alerts caused by layout changes, images, ads, scripts, or dynamic page elements.

Your monitored data stays local in your browser storage. The extension does not require registration and does not send your monitored page content to an external server.

Web Page Change Monitor & Visual Diff is ideal for anyone who needs to keep an eye on important web pages and quickly understand what has been updated.
