DomainOptic uses real-time WHOIS lookups with 99.9% accuracy. Results reflect current registration status. However, domains can be registered at any moment, so if you find one you like, register it quickly to secure it.
WHOIS is a public database containing domain registration details including: registrar name, registration date, expiration date, nameservers, and sometimes owner contact information (if not privacy-protected). DomainOptic pulls this data to show you domain status and registration details.
A registered domain doesn't need to have an active website. The owner might be: parking it for future use, using it only for email, or holding it as an investment. Registered means unavailable regardless of website status.
Enter keywords describing your business or project. Our AI analyzes these keywords and generates creative, brandable domain name suggestions using linguistic patterns and brandability scoring. Each suggestion is checked for availability in real-time.
Our AI optimizes for: pronounceability, memorability, brand potential, and availability. It creates names that sound like real companies, not random word mashups. The goal is names you'd be proud to put on a business card.
Unlimited! Generate as many domain name ideas as you need. There's no cap on usage or daily limits.
Yes. DomainOptic performs passive scanning only - we fetch publicly accessible content the same way your browser does (HTML, JavaScript, common paths like /swagger.json). We do not bypass authentication, exploit vulnerabilities, or access restricted areas. This is the same methodology used by established security tools like Shodan and Censys. Domain owners can request exclusion by emailing brenbuilds@protonmail.com.
Our DNS Health Check examines your domain's email security configuration including: SPF records (sender verification), DKIM (email authentication), DMARC policies (email security), MX records (mail routing), DNSSEC (DNS security), and CAA records (SSL certificate authority restrictions). Essential for ensuring email deliverability and preventing spoofing.
Visit our SSL Checker page and enter your domain. We verify certificate validity, expiration date, issuer details, certificate chain, and security configuration. You'll see how many days until expiration and whether your HTTPS is properly configured.
The Full Site Audit runs four security checks in parallel: SSL certificate verification, DNS health analysis, security header audit (CSP, HSTS, X-Frame-Options), and blacklist scanning. You get an overall security score with detailed explanations for each finding.
Our blacklist scanner (included in the Full Site Audit) checks domains against major spam and malware databases including URLhaus, SURBL, URIBL, SpamCop, and Barracuda. This is essential due diligence before purchasing a domain or diagnosing email deliverability issues.
Yes! Our Domain Comparison tool lets you compare up to 4 domains side-by-side. See availability status, brandability scores, SSL certificate status, and DNS health for each domain to make informed decisions.
Each domain receives an A+ to F grade based on 8 metrics: length, syllable count, pronounceability, sound symbolism, memorability, typo resistance, TLD value, and international appeal. Higher scores indicate stronger brand potential.
DomainOptic is a search and discovery tool. We show you which domains are available and provide direct links to trusted registrars like GoDaddy, Namecheap, and Google Domains where you can complete your purchase.
Standard .com registration is typically $10-15/year. Prices vary by registrar and TLD. Premium or short domains may cost more. We don't mark up prices - you pay the registrar directly.
Popular trusted registrars include: Namecheap (affordable with free WHOIS privacy), Google Domains (simple, transparent pricing), GoDaddy (largest selection), and Cloudflare (at-cost pricing). We link to all of these.
.com is still the gold standard for trust and memorability. If your ideal .com is taken, consider: .co (professional alternative), .io (tech/startups), .ai (AI/tech companies), .app (mobile apps), or .dev (developers). Avoid obscure TLDs that users won't recognize.
A TLD is the extension at the end of a domain name, like .com, .org, .io, or .ai. Different TLDs serve different purposes: .com is universal, .org is for organizations, .io is popular with tech startups, and country codes like .uk or .de target specific regions.
A good domain should be: Short (under 15 characters), easy to pronounce and spell, memorable, free of hyphens and numbers, and unique without trademark conflicts. Use our AI generator to discover creative options that meet these criteria.
Yes, in most cases. Numbers and hyphens are: hard to communicate verbally ("dash" or "hyphen"?), often confused ("five" or "5"?), and look less professional. Stick to letters only when possible.
Yes! Our premium domain list is curated from available .com domains and verified against live WHOIS data weekly. However, since we don't hold domains, they can be registered by others at any time. Act fast on names you like.
We call them premium because they're hand-picked for quality: short length (5-8 characters), pronounceable, brandable, and .com extension. These aren't aftermarket domains with markup - they're standard registration price.
