Oh Dear

Website monitoring that watches more than uptime

About

Downtime happens, certificates expire, and links break. Oh Dear checks your site every minute from multiple locations and tells you the moment something goes wrong. Beyond uptime we watch SSL certificates, DNS records, domain expiry, cron jobs, broken links, mixed content, application health and daily Lighthouse scores. Alerts reach you on Slack, email, Teams, PagerDuty or a webhook. Hosted in the EU, GDPR-friendly, with a signable DPA. Free for 10 days, no credit card.
