Find a domain name across 100+ TLDs
DomaIndex is a free bulk domain availability checker for founders, developers, agencies, and domain researchers. Enter one keyword and check supported extensions in parallel through RDAP, with results arriving as each registry responds.
What you can do
- Check 100+ popular gTLDs, ccTLDs, and newer extensions in one search.
- See available and registered results as they arrive.
- Open registration links for available domains at Namecheap, Porkbun, or GoDaddy.
- Inspect registration, expiry, registrar, and nameserver details when RDAP provides them.
- Choose a custom TLD set, save it locally, and share the exact search URL.
Why DomaIndex
DomaIndex queries RDAP directly, using a structured protocol for domain registration data. There is no signup gate or registrar lock-in, so you can compare domain options before deciding where to register.
