I do not like to disparage competitors, but the issue is that deadlinkchecker.com has far too many false positives and issues that I try hard to avoid or workaround in Bernard. For example, it marks a URL that's a form action destination (https://bernard.app/demo https://bernard.app/demo) as a 404. I technically should return 405 on GET, but it is a false positive nonetheless, because never affects any user. My suggestion is to try both and see what works better for your website.
