Cloudflare Registrar: Pricing, Features & Alternatives

Cloudflare charges exactly what the registry and ICANN charge it and takes nothing on top — a .com is the $10.26 Verisign fee plus the $0.20 ICANN fee, the same number at registration and at renewal, forever. The catch is structural: the domain has to use Cloudflare's nameservers, you cannot register a brand-new name in every TLD it supports, and there is no aftermarket, no parking and no reselling.
