Domaintoolbelt Whois Look

Your domain research toolkit, right in Chrome 🎯
Search, view full WHOIS, track lifecycle status, spot marketplace
listings, and save favorites. All from your browser.

🔍 Instant search with type-ahead
Type any domain and get availability across 200+ TLDs in real time.
Suggests popular endings (.com, .org, .ai) as you type, and detects
the site you're currently on.

📊 Full WHOIS, accurate data
Registration and expiry dates, registrar, nameservers, and lock
status. Includes correctly parsed expiry for tricky TLDs like .is
(Iceland) and .ke (Kenya). Direct RDAP lookups for .me, .edu, .jp,
.ru, .it, .ie, .dk, and .se mean fewer "no data" responses.

🏷️ Marketplace listing badge
See whether a domain is listed for sale on Sedo, Afternic, Atom,
Dynadot, Spaceship, or HugeDomains. Shows the asking price and a
direct link to the listing page.

🔄 Lifecycle tracking
Spot domains in grace period, redemption, or pending delete before
they hit the open market. Useful for catching drops early.

⭐ Favorites and bulk actions
Star domains you're tracking. Manage them, export the list, or open
WHOIS on multiple at once.

🛒 Register direct, no markup
If a domain is free, register it through GoDaddy, Spaceship, Namecheap,
Porkbun, or Cloudflare in one click. No broker, no markup.

⚡ Fast and quiet
First availability response in 50 to 200 ms via cache, then refreshes
with live registrar data. Keyboard shortcut: Alt+Shift+D. Auto-refresh
keeps data fresh.
