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".

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.

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!

DNS record monitoring

We'll monitor your DNS records for accuracy and detect changes.

Having your DNS records change can have big consequences for the availability of your website or API. We'll monitor each record and notify you the moment we detect a change.
