Cheapest .io registrar right now: the short answer
The cheapest .io domain registrar in October 2026 verified pricing is Spaceship at $14.98 for the first year (promo code IO85, limit one per customer) — but read the next line before you celebrate. That same domain renews at $51.75/year, a 3.45× jump. The cheapest renewal anywhere is Cloudflare at $50.00/year (at-cost pricing), followed by Porkbun at $51.80.
There is no sub-$50 .io renewal at any registrar. The honest floor for keeping a .io domain is $50/year — everything cheaper is a first-year promo, and every promo in the table below comes with fine print.
Key takeaway: Spaceship wins year one ($14.98); Cloudflare wins every year after ($50.00). Decide which matters more before you register.
Live .io price comparison (October 2026)
Six registrars, verified October 6–7, 2026. "Year 1" is what you pay on day one; "Renewal" is what you pay every year after — the column that actually determines your cost.
Registrar | Year 1 | Renewal /yr | Transfer | Fine print |
|---|---|---|---|---|
Spaceship | $14.98 | $51.75 | $38.88 | Code IO85, limit 1 per customer; transfer code SPST25 |
Porkbun | $28.12 | $51.80 | $51.80 | Standing public price, no code needed |
Dynadot | $28.89 | $53.50 | $53.50 | Official price list; free WHOIS privacy |
Namecheap | $31.98 | $60.78 | $52.78 | Promo active since Sept 25, 2026; third-party verified |
Cloudflare | $32.00 | $50.00 | $50.00 | Birthday Week promo; renewal is at-cost |
GoDaddy | $59.99 | $89.99 | $89.99 | $0.01 headline requires a 3-year term |
Prices checked October 6–7, 2026 — confirm at checkout, prices change frequently. Namecheap's figures are third-party verified (their site blocks automated checks); Cloudflare publishes at-cost policy rather than a price list.
Key takeaway: First-year prices span $14.98–$59.99 (4× spread), but renewals span $50.00–$89.99 — and you pay the renewal price far more times than the first-year price.
The renewal trap: $14.98 becomes $51.75
Spaceship's $14.98 first year is the best headline price in the industry — and the biggest trap. Here is the 3.45× jump in context, with honest five-year totals:
Registrar | Year 1 | Years 2–5 | 5-year total | Jump |
|---|---|---|---|---|
Spaceship | $14.98 | 4 × $51.75 = $207.00 | $221.98 | 3.45× |
Cloudflare | $32.00 | 4 × $50.00 = $200.00 | $232.00 | 1.56× |
Porkbun | $28.12 | 4 × $51.80 = $207.20 | $235.32 | 1.84× |
Dynadot | $28.89 | 4 × $53.50 = $214.00 | $242.89 | 1.85× |
Namecheap | $31.98 | 4 × $60.78 = $243.12 | $275.10 | 1.90× |
GoDaddy | $59.99 | 4 × $89.99 = $359.96 | $419.95 | 1.50× |
Two things jump out. First, Spaceship still wins the five-year race despite the 3.45× jump — the $14.98 head start is that large. Second, GoDaddy costs nearly double the cheapest option over five years ($419.95 vs $221.98) for the identical domain.
Key takeaway: The cheapest first year and the cheapest five years are different answers. Spaceship wins both here — but only just, and only if you actually use the promo code.
Promo codes and fine print, decoded
- Spaceship $14.98 (code
IO85): limit one domain per customer. Your second .io at Spaceship costs the standard rate. The transfer codeSPST25($38.88) is the cheapest way to move an existing .io in. - Cloudflare $32.00: a Birthday Week promotion announced October 2026 — temporary by definition. The $50.00 renewal is the permanent at-cost figure, and Cloudflare requires you to use their DNS.
- Namecheap $31.98: promo pricing active since September 25, 2026. It will end; the $60.78 renewal is the number to plan around.
- GoDaddy $0.01: the famous penny deal requires buying three years up front — minimum outlay roughly $180. It is not a $0.01 domain.
- Porkbun $28.12 / Dynadot $28.89: the only "no code, no catch" prices on the list.
Cheapest 5-year strategy for .io
- Register at Spaceship with code
IO85— $14.98 for year one. - Before the first renewal, decide: stay at $51.75/year, or transfer to Cloudflare ($50.00/year at-cost) or Porkbun ($51.80/year flat).
- Honestly? For most buyers the simplest winning move is Spaceship year one, then Porkbun or Cloudflare for the long hold. The difference between the top three over five years is under $14.
Is .io safe to buy in 2026? The Chagos question
- The UK–Mauritius treaty transfers sovereignty of the Chagos Archipelago to Mauritius.
- Under IANA policy, if the ISO 3166 code "IO" were ever removed, a retirement process begins — typically five years, extendable by five more.
- No registrar has issued a statement guaranteeing long-term .io support.
- Counterweight: .io has 1.6 million+ registrations, operated by Identity Digital, which recently secured the back-end registry contract for .mu (Mauritius).
- Realistic horizon: even in the worst case, any phase-out would play out over 5–10 years — and Google treats .io as a generic TLD for ranking.
Key takeaway: The .io question is legitimate but not urgent. See our .io domain guide for the full picture.
.io vs .ai vs .com: which extension for a startup?
- .com — still the trust default. ~$12–15/year.
- .io — the tech-startup standard. ~$50/year ongoing.
- .ai — the AI branding signal. ~$80/year ongoing. See the cheapest .ai registrar comparison.
