.si Domain Price: Cheapest Registrars Compared (Oct 2026)

How Much Does a .si Domain Cost?

A standard .si domain costs between $9.99 and $20.35 for the first year at the four registrars we compared (three checked on 27 October 2026, Hosting.com on 3 October), and $11.55 to $23.99 a year to renew. Premium names that a registrar or a reseller has priced up can cost far more.

The floor comes from the registry. Register.si charges accredited registrars €10 a year per domain, before VAT (Register.si), so nobody can sell .si much below that for long. Everything above it is the registrar's margin, its currency rate and whatever promotion it is running.

The rush has not changed the standard price much. Netcraft put a one-year .si registration at about $11 in late September (Netcraft), even as the number of .si domains grew from about 190,000 in early September (Domain Name Wire) to 454,560 on 27 October 2026 (Register.si).

.si Domain Prices at 4 Registrars

We took each price from the registrar's own .si page or pricing API on 27 October 2026; Hosting.com's comes from its domain search on 3 October 2026. Prices are in US dollars for a standard (non-premium) name.

Sources: Hostinger .si page, Dynadot .si page, Porkbun's pricing API and Hosting.com's domain search. Registrars change domain prices often, so confirm the price in the cart before you pay.

The 5-Year Cost Is What Matters

The first-year price is the one in the ads, but you pay the renewal price every year after that. If you plan to keep the name, add the first year to four renewals:

The cheapest first year (Hostinger) is not the cheapest name to own. Dynadot costs $1.56 more in year one and about $20 less over five years, because it renews at $11.55 instead of $16.99. Porkbun charges the most in year one but renews below Hostinger and Hosting.com.

The gap is real money if you hold several names. Five .si domains kept for five years cost about $289 at Dynadot and about $555 at Hosting.com.

Which .si Registrar Should You Choose?

Price is only one part of the choice. Pick by what you need the domain for:

• Lowest total cost: Dynadot. The lowest renewal of the four ($11.55, the same as its first year) and free transfers in. Good if you are collecting several .si names or holding one long term.
• Lowest first year: Hostinger. $9.99, then $16.99 according to its FAQ. Its .si page says its WHOIS privacy service isn't available for .si, and it registers .si for up to 3 years at a time, while the registry allows 5.
• Domain and website in one place: Hosting.com. $14.99, then $23.99 (3 October prices). It costs more to renew, but the domain sits in the same account and DNS panel as your hosting and SSL certificate, with one bill and one support team. Our Hosting.com pricing guide covers its hosting plans.
• Steady pricing: Porkbun. $20.35 up front, then $17.48 a year, with the price published in its open pricing API.

.si vs .ai: The Price Gap

Much of the .si rush comes from people who wanted an AI-sounding domain without paying for .ai. Porkbun lists .ai at $82.70 a year, and .ai must be registered and renewed for at least two years at a time (Porkbun), so the cheapest way in is $165.40 upfront.

Price is not the only difference. Google treats .ai like a generic domain and .si as a Slovenian one, which matters if search traffic is your plan. Our .si vs .ai comparison covers SEO, resale and branding.

Hidden Costs: Premium Names, Aftermarket and Transfers

The prices above are for names nobody has registered yet. Watch for these:

• Premium names. Registrars can price short or dictionary names above the standard rate. Dynadot's .si page says premium domains have different pricing, so check the price shown for your exact name.
• Aftermarket prices. Many good .si names were registered in September to be resold. Netcraft found that about 52% of the .si domains it saw registered at Dynadot between 19 and 22 September were listed for resale there by 23 September, at prices above the registration cost (Netcraft).
• Renewal jumps. A first-year discount often renews at a much higher rate. Read the renewal price on the checkout page, not just the headline price.
• Transfers. Dynadot and Porkbun list .si transfers at $0.00, but Hostinger and Hosting.com don't publish a .si transfer price on the pages we checked, so ask before you move a name there. Check the domain's expiry date after any transfer so you know when the next renewal is due.

How to Pay Less for a .si Domain

• Check availability first, for free. Type the full name, such as yourname.si, into our Domain Checker before you open a registrar's cart: it asks the .si registry directly and checks the same name on .com, .ai and the other popular extensions.
• Compare renewal prices, not first-year deals. The 5-year table above is the honest comparison.
• Register for several years where renewals are low. The .si registry allows 1 to 5 years per registration, which also protects you against a missed renewal email.
• Move after year one if renewals are high. Ask your registrar for the authinfo code and transfer the domain to the registrar with the lowest renewal. Our .si domain guide explains the steps.
• Skip speculative resale listings. If a name is listed for resale, try close variants that are still free to register.
• Check who holds a taken name. A WHOIS lookup shows the registrar and dates, and the Domain Age Checker shows whether it was registered during the September rush.
