Is that .com available?
The registry's own answer, live from RDAP — not a DNS guess that gets it wrong on domains registered but not yet pointed anywhere. One name or a hundred.
We assume .com — registry-truth availability via RDAP, free, no signup.
Why RDAP beats a DNS check
Most free checkers do a DNS lookup: they ask “does this name resolve to a server?” and call it available when nothing answers. But a domain can be registered and sit with no DNS records for months — parked, held, or freshly grabbed. DNS says “free”; the registry says “taken.”
RDAP asks the authoritative source directly — Verisign's registry for .com. A 404 means genuinely unregistered; a 200 means taken. No inference, no false positives.
We validated both approaches against Namecheap on 150 domains: RDAP got 150/150, while DNS only managed 134/150— 16 registered domains with no DNS records looked available and weren't. That's the difference between chasing a name you can register and one that's already gone.
Frequently asked
- Is this really free?
- Yes. RDAP is a free, keyless public query against the .com registry, so the availability check costs us nothing and we pass that on. No signup, no limit on single checks.
- Why only .com?
- Namedry is a .com shop end to end — the drop list, the scorer, the checker. If you type a bare name or a non-.com domain, we assume the .com and check that.
- The name shows available — can I register it here?
- Not on namedry itself — the Buy button links you to a registrar (currently Namecheap) with the name prefilled, and most of these register for ~$10. The availability answer here is live registry truth.
- How many can I bulk-check?
- Up to 100 per run. They're checked one at a time with a short pause between them because the registry throttles bursts — patience beats a rate-limit block.
