Oh Dear

Sep 21, 2018

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.

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.
  • 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.
  • Loved by Humans & Developers: Our human users are happy with the documentation and speed, developers will love the API and webhooks that allow you to automate Oh Dear! as you see fit.
  • Instant Alerts: Get notified instantly when something goes wrong. Via e-mail, Slack, HipChat, SMS, Pushover... You decide how we can reach you.

Website monitoring. Without the hassle.

Hi! My name is Mattias Geniar and together with my partner Freek Van der Herten we founded Oh Dear!, a new tool focused on monitoring websites. We both got fed up with existing tools that didn't fit our needs precisely.

We've just completed our first month of public beta at Oh Dear!, a new website monitoring tool I've been working on for the last couple of months with my buddy Freek. I'm excited to show it to you!
