// EDITOR'S TAKE
Uptime Kuma handles the uptime and certificate expiry checks well but stops there, so you lose the broken link crawling and content checks that make OhDear! distinctive. Checkmate is the broader self-hosted option, adding server and container monitoring alongside websites, and StatusScout is the only project here that also crawls for broken links, though at its size it is an experiment rather than something to depend on.
