.app domains and subdomains
The GetDomainLists release contains 1,234,691 registrable .app domains and 4,220,650 subdomains under them — names only, as historical observations, not a list of live websites.
The subdomain file has 3.4 .app names for each registrable .app domain in the domain file, against 3.4 across all top-level domains. This is a ratio of file rows, not a typical count for one site: many domains have no subdomains in the file. 10.7% of .app subdomain rows sit under a few shared namespaces (vercel.app: 452,456); group rows by registrable domain before reading raw totals. The most common tracked leftmost label is www (696,960 names, 16.5% of .app subdomains).

Shared namespaces under .app in this release (row counts, not ownership or activity):
| Namespace | Subdomains | Share |
|---|---|---|
vercel.app | 452,456 | 10.7% |
ngrok-free.app | 372 | <0.1% |
netlify.app | 1 | <0.1% |
Getting only .app
The release is sold as two complete files covering every TLD in it, not as per-TLD lists. To keep only .app, filter the files you download, for example:
zgrep -E '\.app$' getdomainlists-2026-09-28-domains.txt.gz > app-domains.txt zgrep -E '\.app$' getdomainlists-2026-09-28-subdomains.txt.gz > app-subdomains.txt
Try the format first with a free sample of 1,000 .app domains (plain text, no sign-up). Both full files are $9 once, with 30 days to download.
Limits
- Historical observations collected up to this release (updated 28 September 2026); not proof that a name is registered, resolves or hosts a website today.
- Coverage is incomplete and uneven; these counts describe this release, not the whole .app namespace.
- Names only: no owner, contact, hosting or registration-date data.
