Monitor Website Uptime and Alert via Twilio SMS

This n8n workflow automates website and service monitoring by triggering periodic HTTP requests to a specified URL. It evaluates the response status code: if it's 200 (OK), the workflow silently ends; otherwise, it dispatches an immediate SMS notification via Twilio to alert administrators of potential downtime.

Key benefits include proactive outage detection without manual checks, reducing response times from hours to minutes. It's highly customizable—adjust check intervals (e.g., every minute), tweak alert messages, or scale to monitor multiple endpoints. Integration with Twilio ensures reliable delivery to mobile devices, perfect for on-call teams.

Ideal use cases span IT operations, DevOps, e-commerce, and SaaS providers: monitor API endpoints for fintech apps, track e-commerce site availability during peak sales, or watch internal tools in enterprises. Setup takes minutes, saving hours of custom scripting and enabling 24/7 vigilance with minimal overhead.
