Updated: October 22, 2026 | Prices in USD
A .io domain advertised for $14.98 might cost more than $50 a year to keep. A .ai domain listed at $79.98 per year requires at least $159.96 upfront because the extension has a mandatory two-year registration period.
That distinction matters more than the headline discount.
We compared published registration and renewal prices from seven widely visited providers: Cloudflare, Namecheap, Hostinger, GoDaddy, Porkbun, Dynadot, and Spaceship.
Our findings:
Spaceship has the lowest advertised .ai registration price and the cheapest .io introductory offer among these registrars. Cloudflare has the lowest listed .io renewal rate, while Namecheap's renewals are substantially higher than some older comparisons suggest.
These findings come from official published pricing pages, not completed checkout transactions. Premium domains, regional taxes, and other checkout charges may differ.
Cheapest .AI Domain Prices - October 2026
The .ai extension belongs to Anguilla, but its association with artificial intelligence has made it popular among startups, AI applications, and technology companies.
Unlike .com or .io, .ai requires an initial registration of at least two years. A registrar displaying an $80 annual price is therefore generally asking for about $160 upfront.
Registrar | Initial 2 years | Next 2-year renewal |
|---|---|---|
$159.96 | $159.96 | |
$160.00 | $160.00 | |
$165.40 | $165.40 | |
$171.20 | $171.20 | |
$179.96 | $229.96 |
Prices shown for standard, non-premium domains. Two-year totals are calculated using each registrar's published prices.
Spaceship: Lowest published .AI price
Spaceship advertises $79.98 per year for registration, renewal, and transfer.
A new .ai domain therefore costs $159.96 for the required two-year registration. Its published renewal rate is identical, rather than jumping after the introductory period.
That makes Spaceship an attractive choice for someone who plans to retain the domain beyond its initial registration.
Cloudflare: Almost the same price, with a DNS restriction
Cloudflare Registrar lists .ai at $80 per year for registration and renewal. The two-year registration costs $160, just four cents more than Spaceship.
Cloudflare's registrar operates without a markup on registration and renewal costs, but that does not mean registry-driven prices can never increase.
There is another important restriction: domains registered through Cloudflare Registrar must use Cloudflare's nameservers. Cloudflare confirms this in its registrar documentation.
If you already want Cloudflare DNS, that may be convenient. If you need independent control over authoritative nameservers, choose another registrar.
Porkbun and Dynadot: Competitive alternatives
Porkbun charges $82.70 per year for standard .ai registrations and renewals. That works out to $165.40 for two years, with free domain privacy among its included features.
Dynadot lists .ai at $85.60 per year, equivalent to $171.20 for two years, with the same published renewal rate.
Both remain relatively close to Spaceship on price.
Namecheap: Check the renewal before buying
Namecheap currently lists a two-year .ai registration at $179.96, followed by a $229.96 two-year renewal.
It includes free lifetime domain privacy for eligible registrations, but it is not the lowest-cost option in this comparison.
To illustrate the difference, at today's published prices a .ai domain held for four years would cost approximately $319.92 at Spaceship versus $409.92 at Namecheap.
What about Hostinger and GoDaddy?
Hostinger advertises a $89.99 first-year price within a required two-year term, with a displayed standard renewal rate of $109.99 per year. Buyers should confirm the complete two-year charge in the cart, rather than doubling the promotional first-year figure automatically.
GoDaddy's developer/API pricing documentation provides an example of $159.98 for an initial two-year .ai registration, $239.98 for a two-year auto-renewal, and $319.98 for a standard two-year renewal. These are API-channel figures, not a guarantee of identical retail checkout pricing.
The lesson is to compare renewal terms, not just the registration discount.
Cheapest .IO Domain Deals - October 2026
The .io extension is popular with software developers, SaaS companies, API providers, and technology startups. Unlike .ai, it supports standard one-year registration terms.
That creates more opportunities for introductory discounts, but it also makes the renewal price especially important.
Registrar | First year | Annual renewal | Estimated 5-year total |
|---|---|---|---|
$14.98 with | $51.75 | $221.98 | |
$32.00 | $50.00 | $232.00 | |
$28.12 | $51.80 | $235.32 | |
$28.89 | $53.50 | $242.89 | |
$31.99 | $74.99 | $331.95 | |
$34.98 | $75.98 | $338.90 |
Five-year estimates assume one introductory year followed by four renewals at today's published rates. Future prices are not guaranteed.
Spaceship: Best introductory .IO promotion
Spaceship's official promotions page advertises a .io registration for $14.98 with coupon code IO85.
Promo code: IO85 - $14.98 for the first year
That's substantially cheaper than the regular $51.75 annual price displayed on Spaceship's dedicated .io page.
There are limitations. Spaceship says promotional coupons are restricted to one coupon per domain per customer, apply to new first-year registrations, and exclude premium domains.
A buyer who maintains the domain for five years at today's renewal price would spend approximately $221.98 in total.
Cloudflare: The cheapest published .IO renewal
Cloudflare currently lists .io registration at $32 and renewal at $50 per year.
That makes its renewal the cheapest among the seven registrars examined, even though the initial registration costs more than Spaceship's promotional offer.
Over five years, Cloudflare's estimated total is $232, compared with Spaceship's $221.98.
The difference is relatively small. Buyers who value Cloudflare's DNS ecosystem may reasonably prefer it over an introductory coupon.
Porkbun: Another strong long-term option
Porkbun lists .io at $28.12 for the first year and $51.80 for subsequent renewals.
It includes free WHOIS privacy, SSL certificates for supported domains, domain forwarding, and email forwarding.
At these prices, its estimated five-year total is $235.32, just $3.32 more than Cloudflare.
Dynadot: Competitive registration, slightly higher renewal
Dynadot currently advertises $28.89 for a new .io domain and $53.50 for renewal.
Its five-year estimated cost is $242.89.
The difference from Porkbun is modest, so buyers already managing domains through Dynadot may find the convenience worth the extra expense.
Namecheap and Hostinger: Watch recurring costs
Namecheap's published .io pricing is $34.98 for a first-year registration and $75.98 for renewal.
Hostinger advertises $31.99 for the first year and $74.99 annually to renew.
These providers may make sense for buyers who prefer their existing account, support arrangements, or hosting integrations. However, their standalone .io pricing is less competitive over several years.
GoDaddy is also worth checking, but its retail price should be verified independently. Its published developer/API example shows $29.99 for initial .io registration and $69.99 for discounted auto-renewal, with a higher standard renewal price.
The Important Difference: First-Year Discounts vs Lifetime Cost
A discount on registration does not necessarily reduce the cost of keeping a domain.
For example, Spaceship's .io promotion is $14.98 for the first year, but the published renewal is $51.75. The initial discount is valuable, although the recurring expense is more than three times the promotional registration price.
Cloudflare reverses part of that trade-off: its $32 introductory price is higher, but its $50 renewal is slightly lower.
For a short-term project, first-year cost may dominate the decision. For an established SaaS brand, recurring fees, DNS control, domain transfer policies, and account security can matter more.
Does .AI or .IO Give You Better Google Rankings?
Neither extension provides an automatic SEO advantage simply because it is associated with technology or artificial intelligence.
Although .ai and .io are technically country-code top-level domains, Google Search Central lists both among the country-code extensions it treats as generic for geographic targeting.
Choose between them primarily on branding, audience expectations, available names, and long-term cost.
An AI company might prefer .ai because visitors immediately associate it with artificial intelligence. A developer platform may prefer .io because that extension is already familiar within software communities.
One Long-Term Consideration for .IO Domains
The future governance of .io has attracted attention because it is the country-code extension for the British Indian Ocean Territory.
In a November 2024 explanation, ICANN discussed how a sovereignty change involving the Chagos Archipelago could affect .io.
If the ISO country code were eventually removed, a domain-retirement process could apply, generally involving a five-year phaseout window with possible extensions.
This is not an announcement that .io is being discontinued. The extension remains active in IANA's registry, and the treaty had not been ratified as of the Mauritian government's October 14, 2026 update.
For a permanent business identity, the issue is worth understanding, but there is no basis here to claim that existing .io domains face an announced shutdown.
Which Registrar Should You Choose?
- For a new .AI domain: Spaceship offers the lowest published price in this comparison, at $159.96 for the required two years.
- For the cheapest .IO registration: Spaceship's IO85 code brings the first-year price to $14.98, subject to promotional eligibility.
- For the lowest .IO renewal: Cloudflare lists $50 annually, with the trade-off that Cloudflare nameservers are mandatory.
- For another competitively priced option: Porkbun offers close long-term pricing and several included domain-management features.
- For buyers already using Namecheap, Hostinger, or GoDaddy: Compare the full renewal quote against the convenience of keeping domains with an existing provider.
The final decision should be based on the total ownership cost, not whichever registrar places the biggest discount percentage next to its checkout button.
