Terms & Acceptable Use

This service is provided free of charge, without any warranty, for personal and educational use. It may be changed, rate-limited or taken offline at any time, and there is no guarantee of availability, accuracy or fitness for any particular purpose.

You may only analyze systems, domains, IP addresses, files or data that you own or are explicitly authorized to test. The analyzer performs legitimate diagnostics only — it fetches the public target you specify and performs DNS lookups and technology/CDN detection for that target.

You must not use this project for:

• illegal or unauthorized scanning, probing or testing;
• abuse, harassment, spam or excessive automation;
• scraping, denial-of-service attempts or other attempts to overload targets or this service;
• credential abuse, distributing malware, phishing, or circumventing security or access controls.

Technology detection is heuristic, not proof. Results can be incomplete, outdated or simply wrong — client-side rendering, caching, bot protection and hidden infrastructure all reduce signal quality. Treat low- and medium-confidence results as informed hints, not facts.

The URL you enter is transmitted to the server to perform the requested check. URLs that embed credentials (for example https://user:pass@host) are rejected.

Please use the service reasonably. Automated, high-volume or scripted usage that degrades the service for others is not allowed, and requests may be throttled or blocked to keep the project available.

To the fullest extent permitted by law, the operator is not liable for any damages arising from use of this hobby project, including reliance on its results or any consequences of analyzing a target. Mandatory statutory liability remains unaffected.

These terms may be updated as the project evolves. The current version always applies; see the “Last updated” date above. See also the privacy policy.
