Keeping your website free of broken links is essential for good user experience and SEO - that's why Oh Dear monitors your entire website! Our broken links crawler will find and test all the links on your site and we keep going until we have checked everything!

At Oh Dear, we’re always looking for ways to make web monitoring easier and more efficient for our users. That’s why we’re excited to introduce Tag Notifications, a new feature that expands our notification options beyond site and team-level notifications.

We know how crucial it is to provide clear and timely communication during incidents or downtime. That’s why we’re excited to introduce Status Page Update Templates - a new feature that makes it even easier to keep your users informed while maintaining a consistent message.

We recently announced a new feature to enhance how you communicate with your users during maintenance, incidents, and general service updates. Status Page Templates allows you to save and re-use status updates - but how do you know what incidents might happen or what updates you need to keep users informed about until it's too late? We have put together a library of ready-to-use templates designed to keep your users informed with clear, concise and consistent messaging.

Oh Dear offers several ways to keep you updated on important events like downtime, performance and DNS changes, broken links, Lighthouse issues, and more. By default, you will get email notifications to the email address you used to sign up. But you can also choose to receive alerts to your preferred platform. A popular choice for many of our users is Microsoft Teams.

We know that keeping track of downtime and other failures across multiple sites can be a challenge, especially for larger teams. That’s why we’ve added filters to the 'History' page and introduced 'Team History' to make monitoring easier and more efficient!

Oh Dear can perform many checks: uptime, broken links, scheduled jobs, DNS, and much more. We proud to announce that we’ve added a new check: sitemap monitoring. This check will make sure that the structure of your sitemap is correct. We’ll also check if each and every link it links to a page that returns a correct response. Whenever we detect a problem, you’ll be notified via one of our many supported notification channels.

One of the most unique features Oh Dear offers is the broken links and mixed content crawler. We will crawl your site for all links, reporting any broken pages to your defined notification channels. Recently, we encountered degraded performance with our crawler service due to a breaking change in an underlying library called Guzzle. This caused HTTP 505 responses on the first page of each site, blocking further crawling and resulting in false positive reports.

Our service can detect various problems with your website: whenever it is down, or a broken link is detected, your cron job isn't running on time, and much much more. Whenever we see a problem we can notify you via email, Slack, webhooks, and various other channels. Up until now, you could configure these notification channels in our UI, but now you can do this via our API as wel.

Website monitoring should be simple, intuitive & affordable. That's why we built Oh Dear!

We offer multi-location uptime monitoring, mixed content & broken links detection and SSL certificate & transparency reporting. There's an API and kick-ass documentation too.

Here's what Oh Dear! has to offer:

  • 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.
  • Broken Links Detection: Nobody wants to hit a 404 page. We can automatically notify you as soon as we detect a broken link on your site.
  • 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, HipChat, SMS, Pushover... You decide how we can reach you.

Website monitoring. Without the hassle.
