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.
