I would consider transferring my domains to CF. However, I can’t see pricing unless I enter one of my domain names. When I do, I get a message that my domain is locked (as it is!), so I can’t see pricing. I AM NOT GOING TO UNLOCK MY DOMAIN JUST TO SEE PRICING!
Cloudflare offers domains at the wholesale price of the registry plus the ICANN fee if applicable. This means for a particular TLD, the price could vary depending on the actual domain name where registries are charging premiums for shorter/special/premium names. Many registries also prohibit publishing wholesale price lists.
If you want a price estimate you can enter any domain name for the TLD, but the final price requires your actual domain.
