Alternatives to Gatus
Config-as-code health dashboard, self-hosted
Gatus ranks #6 of 8 in Uptime monitoring, with an Alt Score of 82. It is licensed under Apache-2.0, free and available on Windows, macOS and Linux. 8 of 10 checklist rows are verified against a public source.
Developers, SREs, and small teams who want to self-host their own service health monitoring and status page instead of relying on a third-party SaaS.
Gatus actively health-checks your endpoints (HTTP, TCP, ICMP, DNS, and more) on a schedule, rather than waiting for real user traffic to reveal problems. You define conditions on status codes, response times, response bodies, and certificate expiry, and get alerts through Slack, Teams, PagerDuty, Discord, and 30+ other integrations. It also serves a public or private status page with uptime history, plus Prometheus metrics and shareable uptime/response-time badges.
You describe each service to monitor as an endpoint in a YAML config file, specifying the URL/host, check interval, and pass/fail conditions. Gatus runs as a self-hosted binary or Docker container, continuously executing those checks and updating a built-in status page while firing alerts to configured channels when conditions fail.
