As answered by people managing DevFinanceTools and ZoneWatcher.
ZoneWatcher's answer:
ZoneWatcher is the only DNS monitoring solution that integrates directly with dozens of DNS service providers such as AWS, CloudFlare and Azure. This allows us to fetch your DNS records in full and quickly detect changes in minutes, not in days.
ZoneWatcher's answer:
ZoneWatcher focuses on providing tools to system administrators, IT teams, agencies, and consultancies which manage many domains.
ZoneWatcher's answer:
It began in 2016 out of some frustration I was having with consulting clients who would modify their DNS records incorrectly, breaking their email and/or website until I was able to get them back online. It was frustrating digging through emails or technical documents to find the original values before they had made their changes.
I wanted a tool that could automatically backup those records to make reverting easy while at the same time notifying me of any changes so issues could be proactively fixed before their business was impacted.
