NameSilo

NameSilo is a favorite among budget-conscious buyers and domain investors for its consistently low, transparent pricing that includes free WHOIS privacy for the life of the domain. The interface is functional but dated.

They offer strong bulk management tools, an API, and reasonable add-ons like email and SSL. There are no flashy website builders, making it a pure-play registrar focused on value and portfolio management. It's an excellent choice for those who prioritize lifetime low cost over a polished user experience.
