Check domain availability
Enter a full domain or a keyword — we'll try .com first.
What CheckDomain does
Domain availability
Instant live WHOIS lookup — know immediately if a domain is free, taken, or expiring soon.
Watchlist & alerts
Pin any taken domain to your watchlist and get notified the moment it drops, expires, or goes up for sale.
Backorder placement
Queue a backorder on domains approaching expiry. We watch the drop window and attempt registration the moment it frees up.
Dead site detection
Find registered domains with no real content — parked, abandoned, or for-sale pages worth targeting for acquisition.
How it works
Search any domain
Type a name or full domain. We check availability in real time using live WHOIS data — no cached guesses.
Pin it or act on it
If it's free — register it. If taken — add it to your watchlist or place a backorder. We'll do the waiting for you.
Get notified first
When a watched domain drops or becomes available, you get an alert so you can move before anyone else does.
