Gatus
Automated status pages with real-time uptime monitoring to detect website and API downtime before your users do.
Overview
Gatus is a comprehensive monitoring solution designed to help businesses prevent outages and maintain high availability for their digital services. It goes beyond basic uptime checks by offering advanced capabilities like validating JSON responses, checking SSL certificate expiration, and monitoring various protocols including HTTP/HTTPS, DNS, TCP, and ICMP. The platform's powerful test suites allow users to define sequential tests, passing context between API calls to validate entire user journeys and complex business processes, ensuring that critical workflows are always functional.
One of Gatus's core strengths is its ability to integrate seamlessly with existing incident management workflows through smart alerting. It supports over 15 notification platforms, including Slack, Discord, and PagerDuty, enabling instant downtime notifications and proactive incident resolution. Furthermore, Gatus empowers users to create fully automated, transparent public status pages that reflect real-time service health, display detailed incident reports, and communicate maintenance schedules, keeping end-users informed without manual intervention during critical outages. Its open-source foundation and push-based monitoring for private networks make it a flexible and powerful tool for a wide range of monitoring needs.
