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

.app is a Google-operated extension for mobile and web applications, and it is preloaded in browsers as HSTS — meaning every .app site must be served over HTTPS or it simply will not load. That constraint is the point: it removes insecure connections as a possibility rather than as a policy.

## Character

- Operated by Google Registry and included in the HSTS preload list at the extension level, so browsers refuse plain HTTP for every .app domain.
- A valid TLS certificate is not optional — the site is unreachable without one, so factor certificate setup into launch rather than treating it as a follow-up.
- Names it unambiguously as an application rather than a marketing site, which is useful when the product and the company have different names.

## Good for

- Mobile and web applications with a distinct product identity
- Product sites that should never be reachable over plain HTTP
- Companies separating an app domain from their corporate domain

## Consider instead

- [object Object]
- [object Object]

## Frequently asked questions

### Does a .app domain require HTTPS?

Yes, and not as a recommendation. The entire extension is on the HSTS preload list built into browsers, so a .app site without a valid TLS certificate will not load at all. Plan for the certificate as part of launch.

### Who can register a .app domain?

Registration is open — there is no requirement to have published an app. Any registrant restrictions that apply to your registration appear in the registration requirements on this page, read live from registry data.
