Latest scoop
Trigger an on demand uptime & broken links check after a deploy
You can use our API to easily trigger an uptime and broken links check. If you add this to your deploy script, it can find broken links within minutes after your deploy.
A simple uptime monitor simply doesn't cut it anymore.
Here's what Oh Dear! has to offer.
Broken links checking
You will automatically be notified as soon as we detect a broken link on your site.
This includes error messages like "page not found" and "internal server error".
Mixed content checking
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.
Certificate monitoring
Expiration dates, revocation lists, certificate changes, distrusted certificate authorities,... you name it, we monitor it.
Actionable alerts so you know what to fix.
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, SMS, Slack, Discord, HipChat, Pushover... You decide how we can reach you.
