Oh Dear

Oh Dear is a website health monitoring tool built for agencies and teams managing multiple client sites. It checks uptime every minute from multiple locations worldwide, but goes beyond simple "is it up" checks to catch problems a green status dot misses: expiring SSL certificates, DNS changes, failed cron jobs, broken links, performance drops, and mixed content warnings.

You get one dashboard showing every site you manage. When something breaks, alerts route to the right person on Slack, Teams, PagerDuty, Opsgenie, or via webhook. Each client gets a branded status page so they see updates without emailing your team during incidents.

Key capabilities include:

• Uptime monitoring checked every minute from multiple global locations
• SSL certificate tracking with alerts before expiry
• DNS and domain monitoring to catch unexpected changes
• Cron job monitoring for scheduled tasks that fail silently
• Broken link detection through daily crawls of every page
• Performance tracking with daily Lighthouse scores
• Status pages customizable for each client
• Monthly reports showing uptime, performance trends, and SSL health, ready to send with your branding
• 10+ notification channels so alerts reach the right person instantly

Pricing is per site, not per feature. You pay for the number of sites you monitor; every check and every feature is included from your first site. Unlimited team members can access your account. The tool is EU-hosted and GDPR-friendly with a signable DPA and no third-party tracking.

Oh Dear has run over 68 billion checks and sent 39 million alerts across production environments for companies like Laravel, Obsidian, Bitmovin, and Stanford University. It's designed for agencies that need to hear about problems before clients do.
