A .si domain is Slovenia’s country-code web address, now sold worldwide as “super intelligence”, and for an Indian founder it is cheap brand protection but a weak choice for a main website.
StartupFeed Quick Take
- A .si domain costs about Rs 1,970 a year from an India-facing seller, against Rs 575 to Rs 849 for a .in.
- Slovenia’s registry counted 46,066 new .si names in September 2026, up from 3,515 in August, a jump of 13 times.
- Google treats .si as a Slovenian address, not a global one, so it is fine for a redirect but risky as your main site.

What is a si domain, and why the 2026 rush
A .si domain is the country-code top-level domain for Slovenia, run by the Academic and Research Network of Slovenia, known as ARNES, since 1992. Anyone can register one, anywhere, with no Slovenian address and no documents, for one to five years. That is the same open rule India uses for .in.
The rush came from a name change in the United States. On 22 September 2026, US President Donald Trump told the United Nations that artificial intelligence would be called “super intelligence”, or SI. He signed an order on 29 September telling US federal agencies to use the term in their own documents. Read aloud, .si sounds like “superintelligence”, the way .ai sounded like “artificial intelligence”.
Domain investors moved fast. Slovenia’s registry counted 46,066 new .si names in September 2026, against 3,515 in the whole of August. The total crossed 250,000 for the first time on 2 October 2026. The registry’s own spokesperson, Klara Herman, warned against crediting the whole rise to the speech, noting registrations had already risen in May 2026.
One point an Indian founder should hold on to. That US order binds only US government agencies. No company, no search engine and no Indian authority has to call AI “SI”. The whole value of a .si name rests on a bet that the new word sticks.
What a si domain costs in India
A .si domain is cheap, but not as cheap as a .in. An India-facing seller, rsdomains.in, lists the .si at Rs 1,970 a year. Global sellers charge less in dollar terms: Hostinger lists it at $11.99 for the first year and $16.99 to renew, and Dynadot at $12.04, renewing at $13.50. Slovenia’s registry charges every seller a flat 10 euro a year, and each seller adds its own margin.
Set that beside a .in domain, which most Indian startups buy first. Through a NIXI-accredited Indian seller, a .in costs about Rs 575 to Rs 849 for the first year and Rs 625 to Rs 899 a year to renew, before 18% GST. So a .si is roughly two to three times the price of a .in, for a name that points at Slovenia rather than India.
The renewal price matters more than the first-year price, because a brand-protection domain sits in your account for years. The table below uses each seller’s own prices, read on 2 October 2026.
| Domain and seller | First year | Renewal per year |
|---|---|---|
| .si, rsdomains.in (India) | Rs 1,970 | Rs 1,970 |
| .si, Hostinger | $11.99 | $16.99 |
| .si, Dynadot | $12.04 | $13.50 |
| .in, NIXI seller (plus GST) | Rs 575 to Rs 849 | Rs 625 to Rs 899 |
The catch: Google reads si as Slovenian
This is the fact the domain sellers leave out, and it decides whether a .si is worth it. Google treats a country-code domain as a signal that a site is meant for that country. Google keeps a short list of 20 country codes it reads as global instead, because people use them generically. That list includes .ai, .io and .co. It does not include .si.
So to Google, a website on .si is a website for Slovenia. For an Indian startup selling to Indian or US customers, that is a hint pointing the wrong way. The site can still rank, but it starts at a disadvantage, and Google removed the Search Console setting that once let you override the country target back in 2022.
A .si ending also gives no ranking help for the word “super intelligence”. A domain’s letters do not tell Google what a site is about, just as a .london address does not make a site about London. Could .si join Google’s global list later, the way .ai did on 30 May 2023? It could, but Google publishes no way to apply and no date. Plan for today’s list, not a hoped-for change.
If a squatter takes your brand on si
The same open rule that lets you buy your brand on .si lets a squatter buy it first. Security firm Netcraft counted more than 44,000 .si names that copy an existing .ai name letter for letter, and found about 52% of one US seller’s early .si names were listed for resale within days. Among the grabbed names were real brands, including boeing.si.
Here is where an Indian owner faces a harder road than usual. India’s own dispute process, the INDRP run by NIXI, covers only .in and .Bharat names. It cannot touch a .si. A .si fight runs through Slovenia’s own process, which weighs rights recognised in Slovenia, such as a trademark valid there. An Indian-only trademark gives you a weaker claim on .si than you would have on a .in or a .com.
Indian courts can still help through a passing-off action under the Trade Marks Act 1999, as they have for other domains since the Supreme Court’s Satyam Infoway ruling. But a court case is slower and costlier than buying the name yourself. For a two- or three-word brand, one defensive .si registration is far cheaper than any recovery.
Should an Indian startup buy a si domain
It depends on the job you want the domain to do. For most Indian startups the answer is to buy it only to protect the brand or to run a short redirect, and to keep the main site on a .in, a .com or a global code such as .ai. The table below lays out the common cases.
| What you want | Verdict | Why |
|---|---|---|
| Protect your brand name | Buy it | About Rs 1,970 a year is cheaper than any .si recovery |
| A short campaign or AI-product link | Buy it | Redirect it to your main site; no ranking needed |
| Main site for Indian customers | Use .in instead | Cheaper, and Google reads it as Indian |
| Main site for US or global buyers | Not yet | Google reads .si as Slovenian |
| A second copy of your .com on .si | No | Duplicate pages split your search signals |
| A resale bet on “SI” sticking | Your call | Half of one seller’s early names were already up for resale |
If you do want an AI brand on .si, build something on it that earns links on its own, such as a tool or a dataset, rather than a copy of your existing site. A name that depends on Google traffic from outside Slovenia starts behind. A name that earns citations depends far less on what Google assumes about its country.
About the .si Domain
The .si domain is Slovenia’s country-code top-level domain, managed by ARNES since 1992 and sold through 92 accredited sellers worldwide. Anyone can register one for one to five years, with no residency rule. Since September 2026 it has been marketed as “super intelligence” after the US government began using SI for AI.
Your quick checklist before buying a .si:
- Check if your exact brand name on .si is still free, at a seller that bills in rupees.
- Buy the plain brand and one or two obvious misspellings, not a long list.
- Set it to redirect to your real site; do not build a second copy there.
- Note the renewal price, which can be higher than the first-year price.
- Keep your main site on .in, .com or a global code, not on .si.
StartupFeed Insight
The honest read of the .si rush for an Indian founder is that it is a defensive buy, not a growth one. The September numbers are real, but about half of one seller’s early names went straight to resale, which tells you this is an investor trade, not a wave of real websites. The safe move is a single brand-protective .si pointed at your main site, costing about Rs 1,970 a year, while your business keeps ranking on .in. Watch one date: if Google adds .si to its global list, as it did for .ai in May 2023, the maths changes. Until then, treat a .si as a lock on your name, not as a home for your traffic.

What this means for you: If you run an Indian startup or own a brand, a squatter can take your name on .si today as easily as you can. Buy the plain .si of your brand, point it at your main site, and keep building on .in.
