Do that many people maintain domains on multiple registrars? Seems to me like the kind of person for whom this is a problem would have already simplified their own life by picking a single registrar.

I mean, i have yet to find a registrar that has all the TLDs i want. However, most of the TLDs i want i already find too expensive.

If this type of service minimizes "their cut" to the bare minimum, and made it very transparent who it was coming from so i could price check, i would likely use this service because they're bound to have more TLDs (due to aggregation) than typical registrars.

Unfortunately, currently i feel like i'd just be paying a significant premium for something i already find too expensive. And if this isn't true, i see no information to indicate otherwise (at a quick glance, at least).

We do not earn money when you use the site. There is no subscription fee, no premium stuff. We take our cut when you buy a domain from Nuage and/or renew your domains. It is transparent, and just to make sure it is clear, we do buy our domains from Gandi which is accredited by ICANN.

I have two gandi accounts (one for personal, one for business). Managing that can be a pain sometimes. I also use dnsimple for more complicated and team needs. Gandi is cheaper for simpler things, so I want to keep most of my domains there.

Nuage has a very simple UI (much easier to use compared to gandi, imo)
