Key Features

• Uptime Monitoring: Oh Dear checks your websites’ availability from multiple global locations, ensuring downtime is detected and reported instantly. This multi-location verification minimizes false positives and provides a reliable overview of site uptime.

• SSL Certificate Monitoring: The platform tracks SSL certificate expiration dates and notifies users of any changes or issues, helping prevent security lapses and trust issues with visitors.

• Broken Link Detection: Unlike basic monitors that just ping the homepage, Oh Dear crawls your entire website to detect broken links, mixed content, and error pages (like 404 or 500 errors). Notifications include detailed error information for fast resolution.

• Performance Tracking: Oh Dear monitors site speed and performance metrics over time, alerting you to slowdowns or performance drops so you can optimize for a better user experience and SEO ranking.

• Scheduled Task Monitoring: The service keeps tabs on cron jobs and scheduled tasks, alerting you if any jobs fail or are missed, which is crucial for data processing and automation reliability.

• Application Health Checks: Beyond public pages, Oh Dear monitors backend health — disk space, database connectivity, queue status, and more — to catch issues before they impact users.

• DNS & Domain Monitoring: The platform monitors DNS records for unauthorized or accidental changes and tracks domain expiration dates, ensuring your web presence remains uninterrupted.

• SEO & Content Monitoring: Oh Dear includes Lighthouse-based SEO checks and content monitoring, helping maintain usability and search engine performance.

• Public Status Pages: Easily share real-time status updates with users and stakeholders via beautiful, always-available status pages hosted by Oh Dear.
