one.com

one.com publishes its domain-price catalogue in one table with the renewal printed in the next column. Compare that renewal before following a first-year discount, and check whether an offer requires buying hosting as well.

Where it wins

  • Full public price list, renewal beside every price
  • Aggressive first-year and transfer discounts

Where it costs you

  • Renewal often several times the first year
  • Much of the pricing is bundled with hosting
  • Transfer promo is capped per customer
  • WHOIS privacy is not free

Spaceship

Namecheap's younger sibling runs the most aggressive first-year promos in the market while keeping renewals reasonable. Modern stack, clean checkout, prices move often.

Where it wins

  • Deepest first-year promos
  • Modern dashboard and API
  • Renewals stay mid-pack, not punitive

Where it costs you

  • Prices change frequently
  • Young platform — features still landing

Which is cheaper for a .com domain, one.com or Spaceship?

Do one.com and Spaceship include WHOIS privacy?
one.com: not independently verified. Spaceship: free on eligible TLDs. Registry rules can make privacy unavailable on a particular extension at either.
How do I move a domain from one.com to Spaceship?
Unlock the domain at one.com, ask it for the transfer (auth) code, and start a transfer at Spaceship with that code. A transfer usually adds a year to the registration and is paid at the new shop's transfer price — $9.48 for a .com at Spaceship today. A domain registered or transferred in the last 60 days usually cannot move yet.
