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 old 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.
So with that, ZoneWatcher was born. Depending on your plan, we check multiple times per hour and take a snapshot of each zone's records. When a change happens, we record the change and send you a notification so you can review and have the necessary data to revert if it was in error.
Making close to $500/mo now since a major relaunch / feature update back in December with a decent stream of new users every month. No major marketing done yet other than just word of mouth and the occasional reddit post on /r/msp's vendor threads.
