Oh Dear

Oh Dear is a website health monitoring service popular with agencies and developers, especially in the Laravel and PHP community. It checks sites from a real visitor's perspective every minute from multiple worldwide locations, watching uptime, SSL certificate expiration, broken links and mixed content, DNS record changes, domain expiration, cron job execution, and page performance including Lighthouse scores. Rather than gating features behind pricing tiers, Oh Dear includes its full feature set on every plan and simply scales price with the number of monitored sites and servers, from a Solo plan covering 2 sites up to Enterprise levels above 200. It also produces branded, automated monthly client reports and public status pages, making it a natural fit for agencies that need to demonstrate uptime and performance to their own clients.
