Overview
Oh Dear was built to solve a problem its two founders kept running into from opposite sides: Freek Van der Herten, a developer, worried about whether a site's application layer and content were working correctly, while Mattias Geniar, a sysadmin, worried about servers, DNS, and infrastructure staying up. Oh Dear combines both perspectives into one monitoring dashboard.
Rather than being a single-purpose uptime pinger, it bundles website and infrastructure checks that are normally split across several tools, uptime, SSL, performance, broken links, DNS, and scheduled tasks, into one product with one price per site.
Key Features
Every Oh Dear plan includes the full feature set: uptime monitoring, SSL certificate expiration alerts, broken-link scanning, Lighthouse-based performance audits, DNS record and domain-expiration monitoring, scheduled task (cron) monitoring, ping and TCP port checks, and public status pages.
Because there are no feature-gated tiers, single sign-on, two-factor authentication, unlimited users, and status pages are available even on the entry-level Solo plan; only the number of monitored sites or servers changes as you move up in price.
Pricing
Oh Dear's pricing scales purely by the number of sites or servers monitored rather than by feature access, starting at €15/month for 2 sites (Solo) and rising through several tiers up to €399/month for 200 sites (Scale), with custom Enterprise pricing above that.
Annual billing includes two months free compared to paying monthly, and new users get a 10-day free trial with no credit card required, plus a 30-day money-back guarantee.
Key Features
Uptime monitoring — Checks site availability and alerts the team the moment a site or server goes down.
SSL certificate monitoring — Tracks SSL certificate validity and warns before certificates expire or misconfigure.
Broken link and mixed-content checking — Scans sites for broken links and mixed-content issues that can hurt SEO and user trust.
Performance and Lighthouse audits — Runs Lighthouse-based performance checks to catch page-speed regressions over time.
DNS and domain-expiration monitoring — Watches DNS records for unexpected changes and alerts before domain registrations expire.
Scheduled task (cron) monitoring — Confirms that scheduled jobs and cron tasks actually run on time, not just that the server is up.
Public status pages — Publishes a branded status page that subscribers can follow for incident and uptime updates.

Primarily English-language interface and support
Focused on website and infrastructure monitoring rather than full application performance monitoring (APM) depth
