Abstract

Every .dev domain must be served over HTTPS. Google Registry preloaded the entire extension into browser HSTS lists before opening general registration in 2019, making encrypted transport a property of the namespace rather than a per-site configuration choice. Approximately 600,000 domains are registered. The intended audience is explicit in the string: developer portfolios, documentation sites, internal tooling, and open-source project pages make up the bulk of observed use.
