Cloudflare Registrar

Domain name registration is dominated by companies offering large discounts on the initial domain name purchase and then later surprising customers with incremental add-on fees and inflated renewal costs. Cloudflare Registrar will only ever charge you what we pay to the registry for your domain. Security features like two-factor authentication, multi-user support, and a security-focused customer support team gives you peace of mind that your domain is safe.
