27 tools, zero cost, no account needed
SSL checks, DNS lookups, WHOIS, HTTP headers, IP geolocation, port scanning, speed tests, and more. Everything runs in real-time, nothing gets stored. The way it should be.
The tools people come back for. Hit browse all tools for the full list.
Check certificate issuer, validity, and expiry for any domain. See if your HTTPS is actually secure or about to expire.
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. All 27 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.
A developer who was tired of bloated tool sites that want your email before showing you a DNS record. Built it for himself, decided to share.
