# .dev Domain Names — Register a .dev Domain | Name.ai

.dev is a Google-operated extension aimed at developers, developer tools and technical documentation, and like .app it is HSTS-preloaded so HTTPS is mandatory for every domain under it. It reads as unambiguously technical, which is an advantage or a limitation depending on the audience.

## Character

- Operated by Google Registry and HSTS-preloaded at the extension level, so browsers will not load a .dev site over plain HTTP.
- Widely used for documentation sites, developer portals and personal engineering sites.
- Note that .dev was in informal local-development use before it became a public extension, so some legacy tooling and internal DNS still assumes it resolves locally.

## Good for

- Developer portals, API references and documentation
- Open-source projects and engineering blogs
- Internal tooling exposed to a technical audience

## Consider instead

- [object Object]

## Frequently asked questions

### Does .dev require HTTPS?

Yes. .dev is on the HSTS preload list at the extension level, so a valid TLS certificate is required for the site to load in a browser at all.

### Can I use .dev for a local development environment?

It is a public extension now, so pointing local development at .dev can collide with real DNS and the enforced HTTPS. Reserved names such as .localhost or .test are the safer choice for local use.
