Detailed Review

Oh Dear, built by the Spatie developers Freek Van der Herten and Mattias Geniar in Belgium, treats a website as more than an uptime number: uptime checks from multiple locations sit alongside SSL certificate expiry, broken-link crawling, mixed-content detection, DNS and domain-expiry watching, and scheduled-task tracking, so one monitor replaces several single-purpose tools for a small team or agency running client sites.

Monitors can be defined in plain English with AI verification, and the product leans API-first for teams that want monitoring as code rather than a manual dashboard. Primary data is kept in Belgium with Combell, an ISO 27001-certified host, with performance metrics stored separately via ClickHouse Cloud.

Immutable VOF operates from Berlaar, Belgium. Pricing runs from $17 per month for 2 sites or servers up to $439 per month for 200, with a 10-day free trial. Against Checkly or Better Stack, Oh Dear stays narrower — it covers website and endpoint health rather than distributed tracing or infrastructure metrics, and there is no self-hosted option.

What Oh Dear does well

  • Uptime, SSL, broken links and DNS in one check
  • AI-verified, plain-English monitor definitions
  • Primary data hosted in Belgium (ISO 27001 host)
  • API-first, monitoring-as-code friendly
  • Belgian company, EU jurisdiction

Where Oh Dear falls short

  • No self-hosted option
  • Narrower scope than a full APM or infra platform
  • Pricing scales with number of sites/servers
  • Performance metrics stored via a separate subprocessor

Standout feature. One check that covers uptime, SSL, broken links and DNS — built by developers for their own client sites.
