A simple uptime monitor simply doesn't cut it anymore.
Here's what Oh Dear has to offer:
Broken page & mixed content detection
We crawl and index your entire website, just like Google. As soon as we detect a broken link on your site, we'll notify you.
This includes error pages like "page not found", "internal server error" and even "mixed content".
Continuous certificate monitoring
We check all your SSL certificate expiration dates & alert any change we detect.
We give you actionable & user friendly alerts so you know what to fix.
Public status pages
In times of crisis, a public status page allows you to communicate to your clients.
We'll host your status page so it's always available. You can focus on providing updates to your users.
Performance monitoring
We track the speed & performance of your website over time. If we detect your website is suddenly slower, we'll let you know.
You can quickly see if there's a change in performance that needs to be addressed.
Notifications for everything
Receive our notifications on your prefered platform.
Via email, SMS, Slack, Telegram, Discord, Microsoft Teams, Pushover, webhooks,… we can notify you wherever your team is active.

Scheduled task monitoring
Your cron jobs (Linux) and scheduled tasks (Windows) are the heart of your data processing. What happens when they stop working?
We can monitor every task and notify you if they haven't run on their scheduled times. Don't wait for things to escalate, react quickly and fix your scheduled tasks!
To this day, we've run 6 860 201 751 monitor checks and sent out 3 040 884 notifications.
We built an incredibly powerful website monitor we know you'll love.
Don't just take our word for it, here's what our users think:
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.
