Unlimited Website Down Checker - Uptime Robot Alternative

This n8n workflow acts as a powerful, unlimited alternative to Uptime Robot for monitoring website downtime. It periodically checks your sites, intelligently filters out brief outages to prevent alert fatigue, and notifies you only when downtime persists beyond your threshold. Perfect for site owners, agencies, or anyone managing multiple websites without paying for premium monitoring services.

Key benefits include full customization of check intervals, downtime thresholds, and alert methods—no subscriptions needed. Run it self-hosted or in the cloud for free, and extend it to other automations. It uses simple HTTP requests to verify site status, logic nodes to confirm outages (e.g., multiple failed checks), and integrates with email, Slack, or SMS for critical alerts.

Use cases: Track personal blogs, client sites, e-commerce stores, or internal tools. Set up SMS for high-priority sites and email summaries for others. Save time and money while gaining more control than off-the-shelf tools, reducing false positives and enabling proactive maintenance.
