Spaceship is the newer, leaner registrar platform built by the Namecheap team, launched as a standalone brand with low .com pricing and free WHOIS privacy included as standard. The interface is cleaner than most incumbents, the DNS management is modern, and there is a growing API for operators who want programmatic control over large domain portfolios. No historic restrictions on adult TLDs have been documented.
TLD breadth is still narrower than Namecheap proper, and phone support is absent - potential friction if you manage time-sensitive transfers at scale.
