About Gatus
Gatus is an open source tool for automated health checks and public status pages. It watches your services on a schedule and tells you when something stops responding.
What it does
Gatus checks endpoints over HTTP, DNS, TCP and ICMP. Each check can have custom conditions, such as an expected response time, a JSON value or a certificate that is close to expiry. Multi-step test suites can follow a user journey through several API calls. When a check fails, Gatus sends alerts to chat tools and email, and it can publish the results on a status page.
Key features

Who it's for
