As answered by people managing Oh Dear! and React.
Oh Dear!'s answer
Oh Dear!'s answer
Oh Dear monitors the health of the entire website, not only whether a single URL responds. Oh Dear monitors uptime, SSL certificates, DNS records, domain expiration, scheduled tasks, broken links, mixed content, Lighthouse performance, APIs and application health. Oh Dear also gives teams one dashboard for every website they manage.
Oh Dear!'s answer
Oh Dear is a strong fit for teams that manage multiple websites and want to find problems before clients or visitors report them. Every plan includes every monitoring feature, so teams can monitor website availability, technical health and content quality without assembling several separate tools. Broader observability platforms remain better suited to infrastructure telemetry, logs, traces and application performance monitoring.
Oh Dear!'s answer
Oh Dear is built for developers, technical leads, DevOps teams and CTOs responsible for one or more websites. Oh Dear is especially useful for teams managing client websites, website portfolios, recurring reports and incident communication.
Oh Dear!'s answer
Mattias Geniar and Freek Van der Herten founded Oh Dear in Belgium in 2018. Mattias Geniar brought an infrastructure and security perspective, while Freek Van der Herten brought a web-development perspective. Together, the founders built Oh Dear to monitor the complete health of a website rather than uptime alone. Oh Dear has continued to grow through pragmatic product development and direct customer feedback.
Oh Dear!'s answer
Oh Dear is primarily built with PHP, Laravel and Livewire.
