Gatus is a health dashboard that monitors services via HTTP, ICMP, TCP, and DNS queries. It evaluates response times, status codes, and certificate expiration using defined conditions. A single Docker command deploys the stable container to port 8080.
It suits developers who want a lightweight alternative to heavy enterprise monitoring stacks. The alerting list is extensive but the tool remains a single binary. Skip it if you need complex distributed tracing or advanced log aggregation, as it only handles basic endpoint health checks.
