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.
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.
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, Discord, HipChat, SMS, Pushover... You decide how we can reach you.
We offer a no-strings-attached trial. No credit card needed.
I think this is the first Spark application in the wild that I have joined as a paying customer. Pretty neat. 👏
Besides being a joy to look at, Oh Dear! makes monitoring websites and SSL certificates an absolute breeze.
Easy setup, great pricing, need-to-know notifications and stellar support! Oh Dear! is exactly what was missing in my monitoring tool chain!
I'm extremely impressed with the entire project. Really in-depth monitoring and dead simple functionality with a beautiful user interface. 11/10
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.
Oh Dear! a really nice monitoring tool! Just subscribed directly after the beta invite.
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.
Oh Dear! looks really good, it's fast, and it found some mixed content I had. 👌💯
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 ✅!
Oh Dear really helps me to focus on developing PHPMap! I don’t need to check my site manually. Oh Dear does it for me. ❤️
If you haven’t tried Oh Dear!, you should get started! Lovely UI, simple setup and crazy useful.
Oh Dear! Is the bomb, awesome simple UI, easy to setup & maintain.
