Gatus: The Most Advanced Status Page For Developers

Gatus is an open-source, developer-oriented health dashboard and automated status page that monitors services using HTTP, ICMP, TCP, DNS, and more, alerting on failures before users notice.

🚀 Overview

Gatus solves the critical problem of service downtime detection by proactively running customizable health checks independent of user traffic, unlike traditional tools that only alert after issues impact customers.

It's built for developers, DevOps engineers, and self-hosting enthusiasts who need a lightweight, flexible monitoring solution for websites, APIs, microservices, Kubernetes clusters, and internal services.

Created by TwiN as a single Go binary for easy deployment, it provides a beautiful dashboard, public status pages, and integrations with alerting providers to keep services reliable.
