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.
