Gatus: The Ultimate Self-Hosted Status Page for Your Services

What Is Gatus?

Gatus is a powerful, developer-oriented health dashboard that lets you monitor your services with HTTP, ICMP, TCP, and DNS queries — then evaluates the results against your own customizable conditions. Think of it as a self-hosted alternative to Statuspage.io or Pingdom, but one that runs in a single Docker container and requires zero external dependencies.

Built in Go, Gatus is incredibly lightweight — it can run on a $5 VPS alongside your other services without breaking a sweat. It monitors everything: HTTP endpoints, TCP ports, ICMP ping, DNS resolution, SSL certificate expiry, and even checks response bodies for expected content. When something goes wrong, Gatus alerts you through Slack, Discord, Telegram, Email, Gotify, PagerDuty, Teams, and many more channels.

Key Features

Multi-Protocol Monitoring: HTTP/HTTPS, TCP, ICMP, DNS — cover all your bases
Configurable Conditions: Check status codes (200, 404, 5xx), response times, certificate expiry, JSON/XML body content, and more
Rich Alerting: 15+ notification channels including Slack, Discord, Telegram, Email, Pushover, PagerDuty, Opsgenie, and custom webhooks
Beautiful Status Page: Professional-looking dashboard with uptime badges, response time charts, and endpoint groups
Badges for External Use: SVG badges showing uptime percentages and response times — embed them anywhere
Configuration as Code: Everything is defined in a simple YAML file — version-controlled, repeatable, reviewable

Why Self-Host Gatus?

If you run services, you need to know when they are down. Paid status page services charge monthly fees, limit your endpoints, and keep your data on their servers. Gatus gives you unlimited endpoints, full data ownership, and complete control over your monitoring infrastructure — all in a single 5MB Docker image.

Conclusion

Gatus is the gold standard for self-hosted status pages. Its simplicity (a single YAML file + one Docker container) combined with its powerful condition engine and extensive notification support makes it an essential tool for any developer or team running self-hosted services. With 11k+ GitHub stars and an active community, it is battle-tested and production-ready.
