What it does
Oh Dear checks websites from external locations and collects uptime and performance measurements. Its monitoring menu includes SSL certificate health, broken links, DNS, and other checks, so a team can watch more than whether the home page returns an HTTP response. The service checks uptime every minute and verifies failures from a secondary location; it is for detecting site symptoms, not tracing code paths or repairing an outage.
Begin with a site URL and select the checks that match the risks you want to catch. Oh Dear's uptime guide describes a primary location and a secondary confirmation check; the product documentation also lists performance, certificate, broken-link, and DNS monitoring. A sensible first use is to watch a public route and its certificate expiry, then add other checks only when their alerts have an owner. No website was registered or monitored for this listing.
Because the service observes from outside, it can tell a team that a route is unavailable, slow, or has a certificate problem. It cannot by itself explain a server-side exception or determine whether a private queue is backed up. Pair it with internal telemetry if the team needs to move from alert to root cause.
Oh Dear's pricing page says every plan starts with a 10-day trial without a credit card and lists monthly plans by the number of sites and servers. The opened page shows Solo for two sites at €15 per month, Solo Plus for five at €29, and Freelance for ten at €49; annual billing has a separate discount. Check the current plan limits before switching on every available check for a large site portfolio.
Strengths
- The service combines uptime and performance checks with certificate, DNS, and broken-link monitoring.
- A secondary location confirms failures to reduce alerts from one isolated probe.
- Every paid plan includes the same feature set, with plan size based on sites and servers.
Watch out for
- Outside-in checks report site symptoms but do not replace application tracing or server-side logs.
- Teams need to decide which checks should page someone and who owns each alert.
- Plan capacity is based on monitored sites and servers, which can affect the cost of a large portfolio.
Best for
- Web teams that want uptime, performance, and certificate checks from one service.
- Small agencies or site operators who also need DNS and broken-link monitoring.
- Operators who want external evidence and alerting but use another system for root-cause analysis.
