Why .io is Expensive
.io domains cost 3-5x more than .com because:
- High demand: Tech startups love the "input/output" connotation
- Limited supply: Managed by a small registry
- Premium positioning: Priced as a "tech" TLD
Our Recommendation
Best Value: Porkbun at $33.48/year
Lowest renewal price + excellent support + all features included. For .io specifically, Porkbun beats Cloudflare.
Alternative: If you want CDN included, Cloudflare at $35.99/year is only slightly more and includes their full infrastructure.
Consider .com Instead
A .io domain costs ~$33-50/year. A .com costs ~$10-11/year. Over 10 years, you'd save $200-400 with .com. Unless .io is essential to your brand, consider whether a .com alternative might work.
