Latest scoop
Crawling internal vs. external URLs is now a setting
We've added a setting that allows you to choose if we should crawl all internal URLs or the external URLs too.
A simple uptime monitor simply doesn't cut it anymore.
Here's what Oh Dear! has to offer.
Broken links detection
You will automatically be notified as soon as we detect a broken link on your site.
This includes pages that throw an HTTP/404 or HTTP/5xx error.
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.
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, Slack, Discord, HipChat, SMS, Pushover... You decide how we can reach you.
