What is website monitoring?

Website monitoring continuously checks that your site is online, fast, and actually working—not just responding. Oh Dear checks uptime every minute from multiple locations worldwide and also watches SSL, DNS, broken links, cron jobs and performance.

How often does Oh Dear check my website?

Every minute, from multiple locations worldwide. Broken-link crawls and Lighthouse checks run daily.

What can Oh Dear alert me about?

The moment something breaks—a page goes down, a certificate nears expiry, a cron job doesn't run, a link breaks, or a Lighthouse score drops. Alerts reach you on Slack, email, Teams, PagerDuty or a webhook, before your visitors or clients notice.

Do I need to install anything?

No. Oh Dear monitors from the outside, like your visitors experience your site. For application health it calls a health endpoint you expose—still no agent.

Does Oh Dear offer a free trial?

Yes. Oh Dear offers a 10-day free trial with all features included. No credit card required to start.
