It is not, the functionality is the same. I am trying to expand on the functionality to not only support a single setup. we support multiple update paths, validation, DNSSEC, Letsencrypt, byod domain etc. fleet management. It could be a battery powered esp node that you send to another country. there are multiple ways of doing the same thing and what I hope I am doing is making it accessible, easy and good looking.

Fortinet for example have a similar thing, you can within their web interface register a something.fortiddns.com or float-zone.com or others. but if you upgrade the fortigate with a newer model you need to get in touch with their support because the domain is locked to the old hardware.

syncology has their own, I mean there has never been more options, what I am doing is trying to bundle, connect and provide a platform for your own domains, that can support letsencrypt out of the box, that you can use multiple update paths with ipv6 if needed.

long reply, I am genuinely happy for the "why" questions as it allows me to speak about the platform :)

What's the name of that registrar?
