From the people on call

Reliable enough to forget about.

Good monitoring stays out of your way. Until it catches the outage your client would have found first.

Oh Dear detected an issue that our other uptime monitor did not!

From my first contact with Oh Dear, I’ve been blown away by the quality not only of the application, and scope of the entire tool, but also the support, branding and attention to detail.
Richard Underwood Richard Underwood Owner at The Little Web Studio
I was looking for a replacement for Pingdom because it is no longer value for money. It was a no-brainer to switch. You get way more features and the best user experience.

Built for client work

See every site.
Hear about problems first.

Every site you manage in one account. You find out before the client does, and the monthly report shows them what they're paying for.

View / 01Portfolio

One dashboard, every client.

See every client site in one view and spot slowdowns before they become incidents. No clicking through fifteen logins to answer "is it up?"

Explore uptime monitoring
Route / 02Ownership

You hear it first - routed to the right person.

When a page goes down, a cert nears expiry or a cron never runs, the alert goes to whoever owns that client - on Slack, Teams, PagerDuty, Opsgenie or a webhook - not the whole team.

How notifications work
Share / 03Client view

A status page for every client.

Give each client a branded status page so they see updates without chasing your team. Fewer "is it down?" emails during an incident.

See status pages
Report / 04Proof

Client-ready reporting.

Automated monthly reports - uptime, performance trends, broken links and SSL health - sent with your name on them. Prove the retainer without the busywork.

Everything else it watches

A 200 OK doesn't mean your site works.

The checks a green uptime dot misses: an expiring domain, a DNS record someone changed on a Friday.

Common questions

Questions before the first check.

A few practical answers for whoever gets the first call when a site goes down.

What is website monitoring?

Website monitoring continuously checks that your site is online, fast, and actually working - not just returning a 200. Oh Dear checks uptime every minute from multiple locations worldwide, and also watches SSL, DNS, broken links, cron jobs and performance.

What is website health monitoring?

Uptime tells you a site responds; health tells you it works. Alongside uptime, Oh Dear crawls every page for broken links and mixed content, watches certificates, DNS and scheduled tasks, and runs Lighthouse daily - the problems a green 'up' dot can't see.

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 404s, 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 (queues, disk, database) it calls a health endpoint you expose - still no agent.
