Both broadcast "tech," but to different audiences. .ai faces investors and end users; .dev faces fellow engineers.
Anguilla's ccTLD surged with the AI boom. Now the first choice for AI companies.
Registration and renewal costs remain elevated ($100–$150/yr, varies by registrar). Under British Anguillan jurisdiction. Demand risk if AI hype cycle cools.
Observer's Note
The species under the most intense evolutionary pressure since 2023. Stands at the watershed between bubble and permanence.
Managed by Google Registry. HSTS-required, declaring a security stance at the domain level.
HTTPS mandatory (HSTS preloaded).
Observer's Note
Born encrypted. The progeny of security fundamentalism.
Observation Axes
| .ai | .dev | |
|---|---|---|
| Operator | Anguilla's ccTLD. Lingering sovereignty debates around Chagos/BIOT put the underlying ISO 3166-1 code at long-term risk. | New gTLD run by Google Registry. HSTS preloaded (HTTPS required). Operator risk is minimal. |
| Audience | Investors, media, end users. A flag that telegraphs "we do AI" in one second. | Fellow developers. Home base for APIs, SDKs, docs, and libraries. |
| Cost | New registration $80-180/yr; renewals stay steep. Premium names run tens to hundreds of thousands. Still climbing. | New registration $12-18/yr. Stable renewals. Affordable enough to register domains in place of subdomains. |
| Type of Signal | A "product" signal. A badge for startups selling AI as the product. | A "maker" signal. Technical seriousness, belonging to the developer community. |
| Longevity Risk | Geopolitical risk. The possible retirement of the ISO 3166-1 code is actively debated — keep a migration plan in the back of your mind. | Low. Stable as long as Google Registry keeps operating it. |
| Notable Examples | character.ai, perplexity.ai, huggingface.ai (secondary use) | web.dev, flutter.dev, github.dev, vercel.dev |
Verdict
Choose .ai if your product sells AI inference itself and you have marketing budget. Choose .dev for developer tools, docs, and APIs where you want to avoid cost and longevity risk.
