// EDITOR'S TAKE
Gatus is the closest match for the checks-as-code approach, since every endpoint, condition and alert lives in a YAML file you commit alongside the service. Uptime Kuma is friendlier but click-configured and single-region, and OpenStatus is worth a look when you want synthetic checks and a public status page from the same tool.
