Top 5 Domain Extensions for Tech Companies and the Best Registrars to Secure Them

The most recent data from Q1 2025 shows there are 368.4 million global domain name registrations. You might not believe it, but available at your disposal are 1,591 different domain extensions. Well, they’re technically ‘available.’

Your goal should be to secure a top-level domain (TLD), but the extension you select depends on whether your direct domain name match is already taken, whether you want to pay a lot for it, and how relevant and suitable it is to your tech business.

TL;DR: A brief resume of the top 5 TLD extensions and the easy way to register your piece of ‘Internet real estate’

The top 5 domain name extensions for tech brands.

The suitability and relevance of domain extensions have a massive impact on the success of your tech business and say a lot about your brand. Our guide explores the top 5 domain extensions available to tech brands. You’ll learn how each extension affects how your audience perceives you, the SEO benefits, and the credibility of your business for all types of tech brands.

 .com

The .com domain extension will always win: it’s the king of TLDs. It doesn’t matter what niche your business is in; .com is the favored option. As of September 2025, 43.7% of domain name registrations were .com.

Year after year, .com domains are seen as the most professional and the most reliable extension. Many people might not have thought about what “.com” means: it’s short for “commercial.” Any website can use the .com extension—businesses, blogs, general websites, it doesn’t matter.

If you can find a .com extension with an exact match to the domain name you want, we’d suggest taking it. Through registrars like WIX, prices start from $13.35. 

The issue is that the availability isn’t necessarily there, and we wouldn’t necessarily recommend straying too far from your intended domain name simply to secure a .com extension. There are other great options available for tech brands.

That being said, if you can get a .com, the trust factor of your website is generally higher, and the value to your branding is strong. There’s necessarily a technical SEO advantage, but the overall value and trustworthiness of a .com extension outweigh that.

 .tech

This one is an obvious favorite for tech brands. Short for technology, it’s a direct and obvious link to the niche of your business. They’re still a TLD, but more specifically a generic TLD (gTLD). “Generic” simply means it does not represent a specific country or territory.

And what better way to show you’re a tech brand than to have a .net extension? That said, it’s actually one of the least popular domain extensions in terms of usage statistics, accounting for 0.1% of domain name registrations. . net (another very suitable domain name for tech brands) is slightly more popular at 2.3%.

So, why .tech and not .net? The world is your oyster. Because the usage statistics show .tech domains are so low, you should find exact match domains for your brand or chosen domain name. The cost will also be lower, but the relevance is so much higher. 

We would say that the trust factor is slightly lower than .com extensions, but any extension that isn’t geographical technically has slightly lower trust levels.

It’s direct, relevant, low-cost, and an excellent option over the slightly more expensive and similarly trusted .net.

 .io

The .io domains are a relatively new introduction to the domain extension options market. Well, they’re not actually new. Originally, .io domains were a country code top-level domain (ccTLD) originally assigned to the British Indian Ocean Territory. Now, they’re being used to represent tech, gaming, and startup brands.

The link to technology comes from the technical meaning of “I/O,” or Input/Output, in computer science. For that reason, they’re becoming a highly recognizable extension for tech-focused entities. More recently, this extension is associated with cryptocurrency brands.

Originally, .io did have a low trust level, but now that more brands are using it (0.3% of domain registrations in 2025), the truth score is starting to grow. There was some uncertainty about how Google would treat the .io extension and affect SEO, as it is technically and originally a ccTLD. ccTLDs historically rank well. But recent information shows Google treats it as a generic top-level domain like .com, so SEO isn’t affected.

H2 – .ai

The .ai is rapidly becoming a more popular TLD, now accounting for 0.2% of domain registrations. Short for artificial intelligence (AI), it’s common for any business involved to pick an .ai domain extension. Because they’re not as popular and not as relevant to as many businesses, there’s a ton of availability, and the cost is low.

For this article, .ai is a bit of a rogue one. All the extensions we’ve listed so far are suitable for any tech business, but .ai is only relevant to businesses that use artificial intelligence, at least to some degree. It is, however, a very trendy and trustworthy extension. Like .tech, it’s an instant indicator that a business is involved with AI.

There has been a 46% year-over-year increase in the number of created domains since 2024, a trend we expect to see continuing as AI keeps expanding its LLM tentacles into every industry.

.app

The .app is our final amazing TLD for tech businesses. Short for application, this is another niche-specific suggestion that we thought we’d throw in there. Accounting for 0.2% of domain registrations, it is still popular, and only less so because it’s so niche-specific.

But if your tech business is in the realm of software design or software applications, this is a great one. The trust score is moderate compared to .com, for example, but it’s an instant indication that your brand is involved with application development to some degree.

You’ll find your desired domain name is probably available with a .app extension, and the cost won’t break the bank as much as the .com alternative. And according to Google, which launched the extension in 2015, ‘.app is a more secure domain for apps.’

Additional Respectable Extensions For Your Tech Business

• Any ccTLD, but keep in mind that using a country-specific extension will negatively impact your SEO and make you less attractive to a global market.

• .net

• .org (if you’re a tech organization)

• .dev

• .host

Best Registrars to Secure Your Desired Domain Name

Some domain name extensions are far more expensive, with pricing factoring in how popular your domain name is due to high demand for their inherent qualities.

You’ll notice different registrars have different pricing models and benefits. For example, you can buy a domain name with Wix and have access to free website templates suitable for a tech business. It can be complicated and incur additional costs to buy a domain name with one registrar and then attempt to build a website with another. You often have to pay to add your domain name to the website builder.

The best registrars to secure your desired domain name in 2025 are:

• WIX

• GoDaddy

• 123 Reg
• Hostinger

Last Words

Some are better than others. For example, people often compare Wix to GoDaddy, but WIX has a better library of templates available to use and has more additional tools to help you grow your business.

The success of your business depends on the domain extension as much as the domain name and your business model. If you can, .com is the #1 go-to. If your desired domain name isn’t available as a .com or it’s too expensive, we’ve listed plenty of alternative options.
