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 monitors the health of our website and notifies us when it goes down, then comes back up.

We learned that my site goes down much more often than we thought, but never for more than a few minutes at a time. The notification email has an option to snooze, when there are too many events. We like the friendly tone of the messages as well. Setting things up was trivial, and we haven't had to do anything else to keep it going.

Illustrative example on example.com

UP Uptime check example.com is down, confirmed from a second location 09:41
UP Uptime check example.com is back up after 3 minutes 09:44
OD Oh Dear to your inbox Down and recovered, with a snooze button 09:44
No more worrying if a website is down, simple as that.

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.

Report / 04Proof

Client-ready reporting.

Automated monthly reports - uptime, performance trends, broken links and SSL health - sent with your name on them. Show clients what they pay for, without the extra work.

"Up" doesn't mean your site works.

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