Does .admin exist?
No. No — .admin is not a TLD. It's a reserved-feeling word, but it was never delegated to the DNS root.
The full story
'admin' shows up everywhere — admin panels, admin@ inboxes, /admin routes — so .admin feels like it must be registerable. It isn't: no .admin exists in the root zone and ICANN never approved one. If you run tooling, dashboards or ops products and want that vibe, the endings below actually resolve.
What to use instead
.io — The default startup TLD of the 2010s.app — The obvious home for an app.dev — Best value in domains for anything developer-facing
Wondering about another extension? Every real TLD is in the directory.
