Website monitoring. Without the hassle.

Website monitoring should be simple, intuitive & affordable. That's why we built Oh Dear!

We offer multi-location uptime monitoring, mixed content & broken links detection and SSL certificate & transparency reporting. There's an API and kick-ass documentation too.

A simple uptime monitor simply doesn't cut it anymore.

Here's what Oh Dear! has to offer.

Uptime monitoring

Worried your site might go down? We monitor from multiple locations and will report any downtime. Our probes run worldwide and alert you via Slack, mail or a webhook of your choice.

Certificate Monitoring

Expiration dates, revocation lists, certificate changes, distrusted certificate authorities,... you name it, we monitor it.

Learn more

Mixed Content Monitoring

Loading HTTP content on an HTTPS site is blocked in browsers as it poses a security risk.

Our scans will list all pages on your site that have mixed content.

Learn more

Broken links detection

Nobody wants to hit a 404 page. We can automatically notify you as soon as we detect a broken link on your site.

Instant alerts

Get notified instantly when something goes wrong. Via e-mail, Slack, HipChat, SMS, Pushover... You decide how we can reach you.

When I first signed up I just entered my domain and Oh Dear! took care of the rest. I was pleasantly surprised to see changes in my SSL cert chain and mixed content reports.

DevOps is already a full-time job as is, and having Oh Dear! monitor SSL is just one less thing to worry about. It's fast, detailed and easy to use.

Quote from Armin Ulrich, Creator of MadeWithVueJs

We maintain multiple sites, and not all of them get our attention when things are busy. With Oh Dear we now have a lightweight monitoring service taking up the slack. We’re loving it, especially when it tells us everything’s healthy ✅!
