Gatus
Gatus monitors services at configured intervals and evaluates conditions to determine endpoint health.
What Gatus is
Gatus monitors services at configured intervals and evaluates conditions to determine endpoint health. Its documented checks include HTTP, ICMP, TCP, UDP, DNS, TLS, STARTTLS, SCTP, and external push-based monitoring. Conditions can examine status, response bodies, certificate or domain expiration, response time, connection success, and IP. The project describes itself as completely open source and lists API, self-hosted, and web platforms. The free offering has a stated limit of 30 monitors and includes server monitoring, keyword monitoring, and SSL expiry alerts. Paid plans include status pages, with private pages and custom hostnames listed as features; endpoint and status-page limits vary by plan. Alert integrations include Slack, Teams, Telegram, Discord, Google Chat, Matrix, GitHub, GitLab, and other channels, with availability varying by plan. A beta API supports status-page configuration and endpoint management using authenticated requests. The documentation labels test suites alpha; they run endpoints sequentially with shared context. Gatus says it does not retain metrics indefinitely and documents scraping its metrics endpoint for storage elsewhere.
