Nine quick tools that answer the questions that come up when you're trying to understand or fix your internet — without ads, signups, or upsells.
Your live public IP, the country and ASN websites see, and what your browser leaks about your setup. The starting point for any "am I leaking?" question.
OPEN → Privacy · Browser leakWebRTC can expose your real IP even with a VPN on. This test runs the same checks an attacker would and tells you, in plain English, whether your VPN is actually hiding you.
OPEN → DNS · ResolutionLook up A, AAAA, MX, TXT, NS, and CNAME records for any domain. Useful when something's broken and you need to know whether DNS is the cause.
OPEN → Domain · RegistrarWho registered a domain, when, and which registrar's holding the keys. Helpful when you're vetting a sender or auditing a brand-impersonation domain.
OPEN → TLS · CertificateWhat's in the cert, who signed it, when it expires, and whether the chain validates. The quick way to confirm a site is actually who it claims to be.
OPEN → HTTP · HeadersThe response headers any URL serves — status, content-type, security headers (HSTS, CSP), caching, server hints. Good for debugging and security review.
OPEN → Security · CredentialsStrong, copy-paste-ready passwords with tunable length and character classes. Generated in your browser — nothing is sent to us.
OPEN → Email · DeliverabilityQuick syntactic and DNS-level check on an email address — is the domain real, does it accept mail, does the address look deliverable. No signup required.
OPEN → Status · ReachabilityTells you in five seconds whether a site is down for everyone or just you. The "wait, is the internet broken?" tool.
