Oh Dear

Oh Dear is the all-in-one monitoring tool for your entire website, replacing a stack of single-purpose tools with one unified dashboard. It continuously watches uptime, SSL certificates, broken links, mixed content, Lighthouse performance, and scheduled tasks — catching the issues that quietly erode user trust long before customers file a support ticket.

Beyond simple ping checks, Oh Dear crawls your entire site to surface broken pages, mixed-content warnings, and missing meta tags, while DNS, domain, and blocklist monitors keep you ahead of reputation issues. Alerts route through Slack, email, SMS, Discord, Microsoft Teams, Telegram, PagerDuty, OpsGenie, and webhooks, and public status pages let you communicate incidents the moment they happen.

Key benefits:

• Full-site crawling finds broken pages, mixed content, and SEO issues
• SSL and certificate monitoring with expiry and chain-validation alerts
• Cron job monitoring for scheduled tasks and background workers
• Application health checks for queues, storage, and cache layers
• Lighthouse performance tracking to catch regressions in Core Web Vitals
• DNS, domain, and blocklist monitoring to protect sender reputation
• Public status pages included at no extra cost, replacing ~$100/mo in separate tools

Based in Berlaar, Belgium, Oh Dear is an indie European alternative to stacking Pingdom, Statuspage, PagerDuty, and Screaming Frog. Monitoring runs from Europe West alongside South America East and North America West regions, giving you multi-region verification without the data-residency concerns of US-headquartered vendors.
