Terms of Service

The ground rules for using these check tools. Short version: the service is provided as-is, check only sites you are allowed to check, and do not abuse the free limits.

The service

The service provides free online tools that perform technical checks (HTTP, DNS, TLS, registry data, page markup) on addresses you submit, shows the results and exports them to CSV. Optional accounts, monitoring and API access may be offered as paid features; nothing described in these terms changes the free tools.

Acceptable use

Submit only addresses you are entitled to check: your own sites, or third-party public pages at a human, reasonable rate. Do not use the tools for unauthorized vulnerability probing, password or access brute-forcing, DDoS-style load, or as a scraping backend for someone else's service. Rate limits exist exactly to keep the shared capacity fair; attempting to circumvent them (rotating IPs, hammering the API) may lead to blocking.

Report links are unguessable but shareable: anyone who has a link can view that report. Do not submit confidential or internal addresses if that matters to you.

No warranty

The service and its results are provided "as is", without warranty of any kind. Checks are point-in-time observations made from one network location: a site may behave differently from another region, through another CDN edge, or a minute later. Verification of anything important (expiry dates, security settings) should be done against the authoritative source before you act on it. To the maximum extent permitted by law, the operator is not liable for any damages arising from the use of, or inability to use, the service.

Availability and changes

The service may be updated, rate-limited, temporarily unavailable or discontinued at any time. Free capacity is shared with other visitors. These terms may change; the current version always lives at this address.
