Is Lookproof live?

Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.

Is Lookproof free to use?

Yes — the hub reached it with no key and no payment.

What tools does Lookproof have?

47 tools: Site health check, DNSSEC check, Wildcard DNS check, DKIM record check, Reverse DNS check for mail servers, CSR decoder, CAA record check, DNS resolver comparison, ….

Is Lookproof safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• site.health unknown never probed

  One report on a website's security basics: the TLS certificate on port 443 (trust, name, expiry, key), the redirect chains from http:// and https:// with HSTS, CSP, frame protection, Referrer-Policy and cookie flags, and the domain's expiry and EPP statuses from RDAP, each as a section with coded findings. Use when an agent must audit a website or build a site health report; cheaper than the three checks one by one. No score is computed.

• dns.dnssec unknown never probed

  Report a domain's DNSSEC status (secure, insecure, bogus or unknown) as validated by public resolvers, with DS and DNSKEY algorithms, deprecated algorithms, SHA-1 digests and DS records without a matching key. Use when an agent must tell whether a domain is signed, why it fails on validating resolvers, or whether a key rollover left the chain of trust broken.

• dns.wildcard unknown never probed

  Find out whether a DNS zone has a wildcard (RFC 4592): A, AAAA, TXT and MX of a random, uncached name under the domain through public resolvers, with a warning for a wildcard MX that accepts mail for every invented subdomain. Use when an agent must tell whether a subdomain really exists. Input: ?domain=example.com.

  dnswildcardsubdomainsmxrecords

• mail.dkim unknown never probed

  Fetch and validate the DKIM public key record at selector._domainkey for a domain: key type, key size, revocation and syntax, with coded findings. Use when an agent knows the selector (s= in a DKIM-Signature header) and must confirm that the key is published and usable. It does not verify message signatures.

• mail.ptr unknown never probed

  Check reverse DNS for a domain's mail servers: up to five MX hosts, their IPv4 and IPv6 addresses, each PTR name and whether it resolves back to the same address (FCrDNS), with coded findings. Use when an agent must tell whether a domain's mail servers have matching reverse DNS, a common reason for rejected or spam-filed mail.

  emaildnsdeliverabilityptrreverse-dns

• tls.csr_decode unknown never probed

  Decode one pasted PEM certificate signing request (PKCS#10): subject, DNS and IP names, key type and size, signature algorithm and whether the signature matches the key. Email addresses are never returned. Offline. Use when an agent must check a CSR before sending it to a certificate authority. Input: {"pem": "-----BEGIN CERTIFICATE REQUEST..."}.

  tlscsrcertificatespkcs10decoder

• dns.caa unknown never probed

  Evaluate a domain's CAA records (RFC 8659), climbing to parent names up to the registrable domain when the name has none: allowed issuers for normal and wildcard certificates, iodef, unknown critical tags and invalid values. Use when an agent must tell which certificate authorities may issue for a domain, or why a certificate request is refused because of CAA.

  dnscaatlscertificatessecurity

• dns.compare unknown never probed

  Ask Cloudflare and Google the same DNS question, each alone and uncached, and compare response codes and records; different codes (such as SERVFAIL from one) are a warning, different records information. Use when an agent debugs propagation, DNSSEC or resolver-specific answers. Input: ?name=example.com&type=A.

  dnsresolverspropagationdnsseccompare

• dns.https_rr unknown never probed

  Read a name's HTTPS records (RFC 9460, SVCB): priority, target, AliasMode or ServiceMode, alpn (h3, h2), port, IPv4 and IPv6 hints and whether ECH is published, with AliasMode conflicts and missing mandatory keys. Use when an agent checks HTTP/3 or ECH setup. Input: ?domain=example.com.

• dns.lookup unknown never probed

  Resolve chosen DNS record types (A, AAAA, CNAME, MX, NS, TXT, SOA, CAA, SRV) for a name through public resolvers, with TTL, observation time and the resolver that answered. Use when an agent needs the current public DNS answer for a name, for example to confirm that a record change is visible or to read a TXT verification record.

• dns.ns unknown never probed

  Check a zone's name servers: the NS set, the IPv4 and IPv6 addresses of up to eight servers, a single server, servers that do not resolve, all addresses in one /24 or /48, one TLD for every name and in-zone servers that need glue.

Use when an agent audits or cleans up old verification records. Input: ?domain=example.com.

  dnstxtverificationauditrecords

• dns.zone_lint unknown never probed

  Check a pasted DNS zone file (RFC 1035 master format, up to 64 KiB) with $ORIGIN and $TTL: unreadable lines, SOA and NS at the apex, CNAME at the apex or beside other data, duplicates, mixed TTLs in a set, out-of-zone names, NS/MX targets without addresses and SOA timers.

Use when an agent must audit a domain's email security or build a domain health report; cheaper than calling the nine checks one by one. No score is computed.

  domainemaildnssecurityaudit

• domain.rdap unknown never probed

  Look up a domain's registration at its registry over RDAP (RFC 9083, servers from the IANA bootstrap file): registrar and IANA id, creation, change and expiry dates, EPP statuses such as hold or pending delete, nameservers and DNSSEC delegation. Contact data is never returned. Use when an agent must tell when a domain expires, whether it is locked against transfer or why it suddenly stopped resolving.

  One report on a domain's mail setup: MX, SPF and DMARC, plus DKIM for the selectors you give, with coded findings, an overall status and a spoofing protection category (protected, partial, monitoring, unprotected or broken) with its reasons. Use when an agent needs a complete overview of a domain's email authentication in one call instead of four, or must judge how well the domain is protected against spoofing.

  emaildnsdeliverabilityspfdmarc

• mail.check.bulk unknown never probed

  Run the mail configuration check (MX, SPF, DMARC) on up to 20 domains in one request, each with its spoofing protection category.

  Try 31 common DKIM selectors (Google, Microsoft 365, Mailchimp, SendGrid, Mailgun, Zoho, Proton, Fastmail, mailbox.org, Mailjet, Amazon SES and generic names) for a domain and validate every key found: type, size, revocation and testing flag. Use when an agent needs a domain's DKIM keys but does not know the selector. Finding none is a hint, not proof that DKIM is missing.

  emaildnsdeliverabilitydkimselectors

• mail.dmarc unknown never probed

  Look up the DMARC record of a domain or its organisational domain and explain policy, subdomain policy, alignment and reporting addresses, with coded findings. Use when an agent must read which policy a domain asks receivers to apply to mail that fails DMARC, how strict it is, or why DMARC reports do not arrive.

Use when an agent must tell who hosts a domain's mail, which services may send for it, or whether SPF still authorises a provider the domain has left.

  emaildnsmxspfproviders

• mail.spf unknown never probed

  Parse and evaluate a domain's SPF record: the include and redirect tree, qualifiers and the RFC 7208 limit of ten DNS lookups, with coded findings. Use when an agent must tell whether SPF is valid, why mail from a service fails SPF, or whether one more include would exceed the lookup limit.

  emaildnsdeliverabilityspf

• mail.spf_flatten unknown never probed
