.dev domains and subdomains
The GetDomainLists release contains 579,491 registrable .dev domains and 120,873,381 subdomains under them — names only, as historical observations, not a list of live websites.
The subdomain file has 208.6 .dev names for each registrable .dev 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. 22.3% of .dev subdomain rows sit under a few shared namespaces (workers.dev: 14,312,129, pages.dev: 12,616,989); group rows by registrable domain before reading raw totals. The most common tracked leftmost label is www (386,740 names, 0.3% of .dev subdomains).

Shared namespaces under .dev in this release (row counts, not ownership or activity):
| Namespace | Subdomains | Share |
|---|---|---|
workers.dev | 14,312,129 | 11.8% |
pages.dev | 12,616,989 | 10.4% |
fly.dev | 10,925 | <0.1% |
Getting only .dev
The release is sold as two complete files covering every TLD in it, not as per-TLD lists. To keep only .dev, filter the files you download, for example:
zgrep -E '\.dev$' getdomainlists-2026-09-28-domains.txt.gz > dev-domains.txt zgrep -E '\.dev$' getdomainlists-2026-09-28-subdomains.txt.gz > dev-subdomains.txt
Try the format first with a free sample of 1,000 .dev 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 .dev namespace.
- Names only: no owner, contact, hosting or registration-date data.
