The domain built for apps, software and mobile products.
.app is operated by Google and was launched in 2018 as the first HTTPS-only top-level domain. This means every .app website must have a valid SSL certificate, giving visitors a built-in security guarantee before they even look at your content. It is designed specifically for software applications, SaaS products, and mobile apps.
Register your .app domain →Beyond the obvious branding fit, .app offers a practical security advantage: HTTPS is mandatory, enforced at the registry level. This means your app's domain is always encrypted, no exceptions. For software companies where user trust and security are paramount, this structural guarantee adds real value alongside the clear, descriptive extension.
