redirects to secure checkout to complete registration
.dev is run by Google and requires HTTPS on every registered domain, which makes it a technical statement as much as a naming one — it signals a site built and maintained by developers.
Google built enforced HTTPS into the extension's registry rules from launch, so every .dev site is encrypted by default — no separate certificate step to forget.
Since its 2019 launch under Google's registry, .dev has become a default extension for documentation sites, developer portfolios, and open-source project pages, largely because developers already trust Google's registries.
It's most credible when the content matches the audience — actual code, docs, or developer-facing tools — since a non-technical business using .dev can read as slightly out of place to the audience the extension implies.
