Best Domain Extensions for Startups and Small Businesses in 2025
Compare the best TLDs for your startup or small business. Learn which domain extensions signal credibility, which are budget-friendly, and how to choose the right mix.
Choosing the Right Domain Extension
Your domain extension, or top-level domain (TLD), is more than just an address suffix. It signals what kind of business you are, builds trust with visitors, and can even impact how easily people remember your website.
With over 1,500 TLDs available, choosing the right one requires understanding what each extension communicates.
Tier 1: The Gold Standard
.com
The most recognized and trusted TLD worldwide. Users instinctively type .com when recalling a web address. If your budget allows and the name you want is available, .com is always the best choice. Typical annual cost: $8–$15.
Tier 2: Modern Professional
.ai
Originally assigned to Anguilla, .ai has become the defacto TLD for artificial intelligence companies. Using .ai signals you are in the AI space — it is instantly recognizable to investors, customers, and talent. Cost: $40–$100/year.
.io
Popular among tech startups, SaaS companies, and developer tools. .io conveys innovation and technical sophistication. It remains in high demand, making it one of the more expensive alternatives. Cost: $30–$60/year.
.co
Positioned as a .com alternative for businesses. .co is shorter, modern, and globally recognized. Many successful startups use .co as their primary domain. Cost: $15–$30/year.
Tier 3: Industry-Specific
.dev
Perfect for developer tools, APIs, documentation, and coding resources. Google owns this TLD, giving it strong brand association with development. Requires HTTPS. Cost: $10–$15/year.
.app
Ideal for mobile apps, web applications, and software products. Like .dev, it requires HTTPS and is managed by Google. Cost: $10–$20/year.
.design
For creative professionals, design agencies, and portfolio sites. Instantly communicates creative expertise. Cost: $15–$30/year.
.store
Ecommerce businesses benefit from .store because it clearly signals online shopping. It is memorable and descriptive. Cost: $20–$50/year.
Tier 4: Budget-Friendly
.net, .org
These classic extensions are widely available and affordable (.net for technical/network businesses, .org for organizations). They lack the prestige of .com but are universally recognized.
.xyz, .online
Budget-friendly options that work well when paired with a strong name. .xyz has gained traction with tech companies and is often available for under $5/year.
