Free Domain Availability Checker
Type a name. We check 10 popular TLDs in parallel via RDAP — no affiliate-link redirect bait.
How it works
Type a name
Just the label (acme) or a full domain (acme.com). We strip everything down to the first label.
We query 10 RDAP endpoints
.com, .io, .dev, .app, .co, .net, .org, .me, .ai, .xyz — all in parallel.
Read the results
Green = available, gray = taken, amber = registry didn't answer cleanly. Buy where you want.
Frequently asked questions
Is 'available' guaranteed?+
Mostly. RDAP returning 404 means the registry has no record for the domain — it's very likely available. There's still a small race window between checking and registering, and some premium domains may be reserved by the registry.
Why doesn't my favorite TLD appear?+
We default to 10 popular TLDs. We may add more later, or accept a custom TLD list — file an issue or contact us.
Why is one TLD showing 'unknown'?+
Some registries are slow to respond, throttle anonymous queries, or have transient RDAP outages. Try again in a few seconds.
Do you log my searches?+
No. We make the RDAP requests on-the-fly and don't keep a record.
