.dev domain availability checker
Type a name to see whether its .dev is registered, read live from Google Registry's RDAP server. If it is taken, the same name is checked in 17 other extensions below it. A free .dev costs from $8.75 the first year and $12.87 to renew, and like .app it only loads over HTTPS. Just over half the .dev names people checked here (55%) were already registered.
Free, no sign-in. Free names show the price and a Register button; checkout confirms the name with the registrar again before you pay. Every extension at once: domain availability checker; mixed extensions in one list: bulk domain checker.
Six .dev checks, 4 November 2026
Three names we know are registered and three random strings, sent through this checker on the live site. 3 of 3 known names answered taken and 3 of 3 random strings free.
| Domain | What it is | Answer | Time |
|---|---|---|---|
| web.dev | Known site | taken | 12,074 ms |
| go.dev | Known site | taken | 12,194 ms |
| pages.dev | Known site | taken | 251 ms |
| qoy4dvdzbdt.dev | Random string | free | 12,022 ms |
| wwnkw4usvzb.dev | Random string | free | 209 ms |
| v0f4ldrgx5z.dev | Random string | free | 12,173 ms |
Time is from sending the check to the answer arriving, all six in one run. A taken answer can come from our record of names found registered in the past 7 days, which is why some known names answer fastest; a free answer is always asked of the registry.

.dev availability questions
Can I use a .dev name for local development?
Not as a made-up hostname. .dev is a real extension owned by Google, and since Chrome 63 in December 2017 browsers force HTTPS on every .dev name, which broke local setups that used myapp.dev without a certificate. For local work use .test or .localhost, which are reserved for exactly that; register a .dev only for a site you will serve over HTTPS.
Who runs .dev?
Charleston Road Registry, Google's registry company, which also runs .app. It lists no WHOIS server with IANA, only RDAP, so this checker reads pubapi.registry.google. Google's registry is separate from Google Domains, the registrar it sold to Squarespace in 2023: .dev names are bought from other registrars.
What does a .dev cost to keep?
$8.75 the first year at Porkbun and $12.87 a year after that (24 October 2026), $60.23 over five years. That is about $2 a year more than a .com and a quarter of what a .io renews at ($51.80). Dynadot does not quote .dev.
Is .dev only for software developers?
There is no requirement; anyone can register one. Most are developer tools, documentation and portfolios: web.dev and go.dev are Google's, and pages.dev is Cloudflare's hosting, all taken on 4 November 2026. 55% of the .dev names people checked on domhaul were already registered (30 of 55).
