.app domain

Tier 1 · Scanned on every plan, free included.

HTTPS-only by registry policy: every .app domain is on the browser preload list, so it cannot be served over plain HTTP. Reads as a product rather than a company.

How Namescope checks it

Availability comes from RDAP, the registry's own protocol, not from a reseller's search box. When a registry publishes no RDAP endpoint the report says so and links to the manual lookup instead of guessing.

RDAP lookups on the extensions that matter for the plan, with the registry response quoted in the report.
