Signal Slot Monitor - Page Alerts

Monitor selected pages for keyword, availability, stock, appointment, price, or restock changes with local alerts.

Signal Slot Monitor helps you watch selected pages for meaningful content changes. Add keywords such as available, in stock, appointment, restock, price drop, or your own custom phrases. Then start monitoring the active page at your chosen interval. When a matching keyword or relevant page change is detected, the extension can show a local browser alert. The extension works locally in your browser. It does not require an account, does not use payments, does not use license keys, and does not upload your monitoring data to any server.
