Renewal prices

The first year is the hook. Renewal is the bill.

Most registrars win you with a low first year, then charge more every year after. Every renewal is priced from our registrar's cost by the same margin rule, so the price you see is the price you keep paying.

Renewal price per year in US dollars before VAT, by registrar and TLD. The first price column is Registrar Domains.

Renewal per year, in US dollars before VAT, read on 14 October 2026 from each registrar's public price page. Euro prices at the ECB rate of that day. "Us" is Registrar Domains, at our price read on 23 October 2026; the table shows today's price once the page loads. GoDaddy does not publish renewal prices, so it is only on the full table. The lowest price in each row is in bold. All 11 registrars, Cloudflare and Porkbun included, with first-year prices and sources →

For agents

Everything on this page works for your agent.

One MCP server and a REST API with the same tools. Your agent searches, prices and starts the order, then reads your domains and orders. You pay through the link it gives you. Automatic renewal, if you or your agent turns it on, charges your saved card before expiry.

    How buying works

    No password. One payment. Yours in minutes.

    Search, and add the names you want to your basket. Sign in with the link we email you. Fill in the registrant once for every name, then pay once by card. Your domains, DNS, renewals and invoices stay in one account.

    • You pay first, then we buy

      We never pay the registrar before your payment clears. An order that is not paid simply expires.

    • Refund if it fails

      If the registry refuses the registration, you get your money back in full.

    • Our cost is public

      The API shows what our registrar charges us next to what we charge you. The gap is our whole margin.

    • Renewal price up front

      You see the renewal price before you pay. It follows our registrar's cost, with the same margin as the first year. Renew from your dashboard, or from the link in the reminder emails we send 30 and 7 days before expiry. Automatic renewal is off by default. Turn it on per domain in the dashboard, or confirm an agent's request from the email we send you, and we charge your saved card 7 days before expiry, then renew. You can turn it off at any time.
