In plain words

Cabot is an open-source, self-hosted monitoring and alerting system designed to notify users when services experience downtime or when system metrics behave abnormally. It's built for developers and operations teams who need to monitor their infrastructure without relying on external services. The platform allows users to set up alerts based on service availability and metric thresholds, giving teams immediate visibility into system health issues.
