.dev domains

The .dev domain is a generic extension operated by Google Registry and built for developers, engineering teams, and technical projects. Its defining feature is security: the entire .dev top-level domain is on the HSTS preload list, which means browsers will only ever connect to a .dev site over HTTPS. In practice that requires a valid TLS certificate before the site will load, so every .dev domain is secure by default with no option to fall back to plain HTTP. Registration is open to anyone. Developers use it for portfolios, documentation sites, internal tools, project pages, and product landing pages where a modern, security-first address reinforces technical credibility. If HTTPS-only is a requirement rather than an afterthought, .dev enforces it at the registry level.
