# Monitors

Monitors are at the core of Monitoro, and are essentially tools for keeping up-to-date with changes on websites. By periodically opening webpages and extracting data, monitors track updates around the clock, and based on these changes can alert you, keep your spreadsheets up to date, and automate your tasks.

You can create monitors either from an existing template or from scratch for websites not yet covered by our templates. Learn about [creating an instant monitor](/guides/create-an-instant-monitor.md), and a [custom monitor](/guides/create-a-custom-monitor.md) here.

All monitors have the capacity to send alerts and execute automations, empowering users to stay informed and respond promptly to the data they track. Learn about [alerts and automations](/guides/automate-alerts.md) here.
