Look up domain registration data, check WHOIS records, and access historical snapshots to trace ownership and build evidence trails.

Registrars · Hosting providers · SaaS platforms

Registrar integration

SOC analysts · Threat intel · Incident response

Cybersecurity teams

Domain portfolio management

Monitor expiry dates, track WHOIS changes across your portfolio, and discover available domains at scale with the bulk availability pipeline.

our promise

Your lookups are yours alone

When you search for a domain, that query stays between you and us. We never share, sell, or act on your lookup data. If you find a name that's available, nobody will know — not from us.

principle 01

Zero data sharing

Your queries are never sold to registrars, brokers, or anyone else. We don't monetize your search behavior. Period.

principle 02

No front-running

We don't register domains you've searched for. We don't tip off anyone who might. Your discoveries stay yours.

principle 03

Encrypted end to end

All API traffic is encrypted in transit. Data at rest is encrypted using AWS-managed keys.

ai name generator

Find the .com that nobody else found.

In an era where every good .com feels taken, the AI generates tens of thousands of name candidates and multiplies them across your selected TLDs. Describe your product, pick your extensions, and let the pipeline find what's actually available.

  • Tens of thousands of name candidates from a single prompt
  • Multiply across .com, .io, .dev, .app and many more TLDs
  • Instant bulk availability check through the pipeline

Pricing

AWS-style pricing. Pay only for what resolves

Every query flows through Bloom → DNS → RDAP → WHOIS and stops at the first definitive answer. You're billed for the method that actually resolved it — never the steps that came before. Volume discounts kick in automatically.

Free tier: 1,000,000 queries / month (all methods combined)

Each query enters the pipeline and stops at the first method that gives a definitive answer. You pay only for the resolving method — intermediate inconclusive steps are never charged.

Bloom — Accepted without verification. Zero network, nanosecond response. ~0.000001% false positive rate. Eligible TLDs only.
