Is a website safe and set up correctly? One free report covering security, email, DNS, and speed — explained in plain English.
Query A, AAAA, MX, TXT, CNAME, NS records straight from authoritative servers. No middleman.
See what headers a server sends back. Checks CSP, HSTS, X-Frame-Options — the stuff that actually matters for security.
Find out where an IP actually is. Country, city, ISP, ASN, timezone. Useful when you need to know, annoying when you don't.
Check if SSH, HTTP, MySQL, Redis, or any of the top 20 common ports are open on a host. Quick and clean.
Find out who owns a domain, when it was registered, when it expires, and which name servers it's using.
Yes. Use the Website Health Check — enter any domain and get a free report covering SSL, DNS, email, security headers, speed, and more in about 5 seconds. No account needed.
Yes. All 33 tools, no usage limits, no premium tiers, no "create an account to continue". Just open and use.
No. No query logs, no IP tracking. Your lookups run in real-time and stay in your browser. Third-party services (Google Analytics, AdSense, Cloudflare) may use cookies — see our privacy policy.
DNS resolvers, WHOIS databases, the servers themselves (for SSL and headers), and ip-api.com for geolocation. All queried in real-time.
20 requests per minute per IP. That's plenty for normal use. Hit the limit? Wait a minute. That's it.
