Oh Dear is an all-in-one website monitoring platform built to give teams complete visibility into the health of their websites and servers. Launched eight years ago with a mission to simplify uptime and reliability monitoring, the platform now goes far beyond simple checks. It combines global uptime monitoring, SSL/TLS certificate tracking, broken link detection, and SEO and accessibility audits powered by Lighthouse, making it a comprehensive tool for developers, marketers, and operations teams.
With its latest release, Oh Dear expands monitoring deeper into the infrastructure layer. Teams can now monitor TCP services such as MySQL, Redis, PostgreSQL, and RabbitMQ, as well as track server availability with ICMP ping. These capabilities complement its existing features like cron job monitoring, DNS and domain checks, performance tracking, and application health alerts. Whenever downtime, latency, or errors occur, Oh Dear notifies the right people instantly via email, SMS, Slack, Discord, PagerDuty, Teams, and other integrations—ensuring issues are caught before they impact users.
What sets Oh Dear apart is its “outside-in” monitoring approach, covering nearly the full OSI stack—from low-level connectivity to full application performance. The platform also offers hosted status pages for incident communication, giving companies a professional way to keep customers informed. Trusted by tech teams and enterprises worldwide, Oh Dear delivers the reliability, depth, and simplicity needed to keep websites healthy, secure, and running smoothly.
