Register .app domain names with Blacknight


.APP is the new, more secure domain for your app. It’s where developers, entrepreneurs, and businesses showcase information about their apps to the world.

Apps make the mobile world go ‘round, and now they have a special secure home on the web: the .APP domain.

The crucial feature of .APP is that .APP domain names only work with Secure HTTPS. So your users know at a glance that yours is a domain name they can trust.

You can use your .APP name to showcase a unique and trustworthy destination, as a relevant download link, for deep-linking, or for sharing screenshots, release notes, and reviews. Get your .APP domain now to start sharing your app with the world.

Register .APP Domains with Blacknight

.APP is a more secure domain, meaning that HTTPS (Encrypted Browsing) is required for all .APP websites.

The entire .APP domain is encrypted-by-default because the entire .APP domain space has been added to the HSTS Preload list. This means that Chrome and other modern browsers will not load a .APP domain name unless it served over HTTPS.

You can buy your .APP domain name now, but in order for it to work properly in browsers you must first configure it with a Digital Certificate.

  • Do I Need to Be a Registered Developer to Buy .APP?

    No! Anyone can register a .APP domain and use it for whatever they want. However, you must host the .APP website on HTTPS or it will not work. This extra layer of security will keep your users and customers secure. Blacknight can set you up with the right SSL certificate to make sure you comply.

  • Who’s on .APP?

    Global companies like JOIN, Myra, The Podcast App, LBB and PICKLE are all using .APP

  • Is .APP Secure?

    The .APP top-level domain is included on the HSTS preload list, making HTTPS required on all connections to .app websites — no individual HSTS registration or configuration required. The result is built-in web security for you and your users.

  • Can I use my .APP domain name without HTTPS?


    .APP is owned by Google, and it’s part of their campaign to make the web more secure. The entire .APP namespace has been added to the HSTS Preload list, which is used by Chrome and other modern web browsers to validate the security of domain names. Modern browsers will not load domain names on the list unless they are properly configured with HTTPS.

  • What is the HSTS Preload List?

    HSTS stands for HTTP Strict Transport Security. This is a list of sites that are hardcoded into Chrome as being HTTPS only.

    Most major browsers (Chrome, Firefox, Opera, Safari, IE 11 and Edge) also have HSTS preload lists based on the Chrome list.For more information, and to check the status and eligibility of a domain name, visit
