Oh Dear
Monitoring for uptime, certificates and links
Oh Dear monitors websites from the outside and checks far more than whether a page is reachable. Besides uptime it watches SSL certificates, DNS records, broken links, cron jobs and Lighthouse scores, and alerts go to Slack, PagerDuty or webhooks, among others. Outages are confirmed from several locations before an alert goes out, and status pages are included on every plan.
Why it made the cut- Checks uptime, SSL, DNS and broken links
- Monitoring for cron jobs and scheduled tasks
- Status pages included on every plan
