.app domain name generator
.app is a generic top-level domain from Google Registry made for applications. It tells visitors exactly what they are getting before they click. DomainGenTool generates .app names from a description of your product and checks each one against the registry.

- Registration status comes from Google Registry’s public RDAP service.
Example prompts for .app names
Describe the product, the audience and the tone. Try one of these, then ask for shorter names or a different style:
- “A habit-tracking app for students, playful and short”
- “A recipe planning app for busy parents, friendly tone”
- “A secure password-sharing app for small teams, trustworthy”
Frequently asked questions
Do .app domains require HTTPS?
Yes. The whole .app extension is on the HSTS preload list, so browsers refuse plain HTTP. Most hosts such as Cloudflare, Vercel and Netlify issue certificates automatically.
Can I use a .app domain for something that is not an app?
You can, but the extension sets an expectation. It works best when the site is the product or its landing page.
How is .app availability checked?
DomainGenTool asks Google Registry over RDAP. “Registered” is reliable; “Possibly available” should be confirmed at the registrar, where premium pricing may apply.
