A simple uptime monitor simply doesn't cut it anymore.
Worried your site might go down? We have servers worldwide that will report any problem as soon as it happens.
Be the first to know when your site is unavailable.
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".
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.
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.
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.
Receive our notifications on your prefered platform.
Via email, SMS, Slack, Discord, Microsoft Teams, Pushover, webhooks,… we can notify you wherever your team is active.
