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 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.

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.

Instant alerts

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

Protect yourself

The web is moving to HTTPS. Don't let a misconfiguration ruin your site's reputation or availability. Oh Dear! can help you deploy SSL certificates with more confidence.

We offer a no-strings-attached trial. No credit card needed.
