Website monitoring should be simple, intuitive & affordable. That's why we built Oh Dear! We offer multi-location uptime monitoring, mixed content detection and SSL certificate & transparency reporting. There's an API and kick-ass documentation too. -UPTIME MONITORING Worried your site might go down? We monitor from multiple locations and will report any downtime. Our probes run worldwide and alert you via Slack, mail or a webhook of your choice. -CERTIFICATE MONITORING Expiration dates, revocation lists, certificate changes, distrusted certificate authorities,... you name it, we monitor it. -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.
