Host Your Own Uptime Monitoring with Scheduled Triggers

This n8n workflow enables you to host your own simple yet effective uptime monitoring system using scheduled triggers. It reads a list of website URLs from a Google Sheet every 5 minutes, performs HTTP checks to determine if each site is UP or DOWN, and sends immediate email and Slack notifications for any downtime. The sheet is then updated with the current status and a log entry, allowing you to track uptime percentages over time for performance analysis.

Ideal for webmasters managing a few sites who need reliable monitoring without expensive third-party services. Benefits include full customization, low cost (just n8n hosting), and easy scalability by adding more URLs to the sheet. No advanced features required, making it perfect for small teams or personal projects.

Key use cases: Monitor personal portfolios, client sites, or internal tools; integrate with existing Google Workspace; customize alerts for specific downtime thresholds. Easily swap Google Sheets for Airtable or Excel, and adjust schedules or notifications to fit your needs.
