Domain Availability Check
Check if a domain is available, single or bulk
🌍 Domain Availability Check
Check if domains are available. Bulk check up to 1,000 domains at once, with automatic value scoring.
💡 Tip:
Available domains have a 💰 Appraise button — click it to see the estimated resale range.
💡 How to Check if a Domain Name is Available
Checking domain availability is simple. Enter the domain you want (like "example.com") and click Check. Our tool queries the official RDAP (Registration Data Access Protocol) registry in real time.
You will get one of three results:
- Available (Green) — The domain is not registered and can be purchased from any registrar.
- Registered (Red) — Someone already owns it. You can check WHOIS for the owner and expiration date.
- Unknown (Yellow) — Some country-code TLDs don't expose complete data. Try a registrar lookup for these.
Scoring Algorithm
Every available domain gets scored across 5 dimensions to estimate its resale value:
- ① Extension: .com=30 · .ai=22 · .cn=20 · .io=15 · others
- ② Length: 2-letter=30 · 3-letter=25 · 4-letter=15 · 5-letter=8
- ③ Pronounceability: CVCV perfect +20 · no vowels −25 · 4+ consonants −20
- ④ Meaning: common English word +35 · pinyin-like +18
- ⑤ Brand fit: AI / e-commerce / finance prefixes
Grades: 💎 Premium ≥ 88 · 🔥 High Value ≥ 72 · ⭐ Great ≥ 58 · 💡 Catchy ≥ 45
Frequently Asked Questions
What's the difference between RDAP and WHOIS?
RDAP is the modern ICANN-mandated protocol. It returns structured JSON with proper HTTP status codes (200 means registered, 404 means available). It is faster and more reliable than traditional WHOIS, which is plain text and rate-limits aggressively.
Why does it show "Available" but the registrar says it's taken?
There can be a brief propagation delay between the registry and the registrar. Also, some domains are "Premium" — they are technically available but sold at a much higher price. Always confirm on the registrar's checkout page.
Can I check multiple domains at once?
Bulk checking will soon be available for Pro members. For now, you can check them one by one.
