Gatus monitors services on a schedule and checks their health against conditions you define. Its documented endpoint checks cover HTTP, ICMP, TCP, UDP, DNS, TLS, STARTTLS, SCTP, and external push-based checks. Conditions can assess status, response bodies, certificate or domain expiry, response time, connection success, and IP addresses. The product lists server monitoring, keyword monitoring, SSL expiry alerts, and a free plan with a monitor limit of 30. It is available through API, self-hosting, and the web. Gatus also offers plans with status pages and limits that vary by tier. Standard is 10.00 USD per month and includes one status page, 30 endpoints per page, a two-minute minimum check interval, and one team member. Enterprise is 500.00 USD per month and includes 30 status pages, 1,000 endpoints per page, a 30-second minimum interval, and unlimited conditions, alerts, and team members. Alerting integrations include services such as Slack, Microsoft Teams, Telegram, Discord, Google Chat, Matrix, GitHub, and GitLab; availability varies by plan. The project describes itself as completely open source. Its beta API supports status page configuration and endpoint management, while documented workflow test suites are marked alpha.
