Brainstorming Built-In

Build brainstorming directly into your product with the Domainr API. So fast, your customers will think it’s magic.

Real-Time Availability

Instantly check if a domain is available—with no false positives. Domainr is ICANN-accredited, and checks domain registries directly in real-time. Your customers will know in milliseconds if domains are available, premium-priced, or for sale in the aftermarket.

Avoid the frustration of a failed search or a taken domain. Instant, per-keystroke search turns the usual dead-ends of searching for domains into a conversation. With intelligent context-aware suggestion, Domainr surfaces relevant top-level domains, helping your customers find the perfect name—even if the .com is taken.
