.app WHOIS Lookup
Look up any .app domain instantly. FetchWhois queries Google Registry's RDAP server and returns the full registration record — registrar, key dates, nameservers, DNSSEC and contact details — for any .app domain.
How the .app WHOIS lookup works
Live .app RDAP data from Google Registry.
Enter a .app domain name
Type the .app domain into the search box. .app is popular with mobile app products, web apps and software companies.
FetchWhois queries Google Registry's RDAP server
Google Registry operates both .app and .dev with shared RDAP infrastructure. We resolve the .app endpoint via IANA and query it live.
Read the .app registration record
Registrar, dates, status, nameservers and DNSSEC data are returned. Like .dev, all .app websites require HTTPS.
.app domains: Google Registry's TLD for apps and software
.app is a TLD operated by Google Registry, launched in 2018 specifically for mobile applications, web apps, software products and app developers. Like .dev, it is on the HSTS preload list — all .app websites must use HTTPS, enforced at the browser level. .app was notable for raising $25 million in its first year of registration fees, making it one of the most commercially successful new gTLD launches.
WHOIS lookups for .app domains return the same RDAP data structure as .dev: registrar, dates, status codes, nameservers and DNSSEC. .app domains are widely used by mobile apps (both iOS and Android), web applications and software-as-a-service products. They are recognized globally as indicating an application product, making them an effective brand signal.
