Registering a .app Domain
The .app top-level domain is a generic TLD operated by Google Registry. Launched in 2018, it was designed for application developers, mobile apps, web apps, and software companies. Like .dev, the .app extension is included in the HSTS preload list, so all .app websites must use HTTPS.
Why Choose .app?

.appextension is the perfect match for mobile applications, web apps, and software products. - Built-in HTTPS — Every
.appdomain is automatically secured via HSTS preloading, ensuring visitors always connect over an encrypted connection. - Strong availability — Many concise, memorable domain names are still available under
.app. - Trusted extension — Backed by Google Registry,
.appcarries inherent credibility with both users and search engines.

The HTTPS Requirement
Browsers enforce HTTPS on all .app domains through HSTS preloading. A site served on a .app domain without a valid SSL/TLS certificate will not load. Before launching, ensure:
- An SSL/TLS certificate is installed and active on your server.
- All traffic is redirected from HTTP to HTTPS.
- All page resources (images, scripts, fonts) are loaded over HTTPS.

.app vs .dev
Both .app and .dev require HTTPS, but they target different audiences:
| Factor | .app | .dev |
|---|---|---|
| Primary audience | App publishers and software companies | Developers and development teams |
| Branding signal | “This is an application” | “This is for developers” |
| Pricing | Similar | Similar |
| HTTPS required | Yes | Yes |
Choose .app if you are marketing a product to end users, and .dev if your audience is primarily other developers.
