Earlier quoted context omitted.
Last time I checked it lacked real API or a way to be configured via config files. I find Gatus much more thought through. - https://github.com/TwiN/gatus
Not that I think that an API is fundamental to a monitoring tool, but it happens to have one: https://github.com/louislam/uptime-kuma/wiki/API-Documentati...
Not necessarily an API, but a config file would be nice.
Also... there is a big disclaimer at the very top of the page.
