Know the limits. This is a static GitHub Pages application. Browsers cannot perform arbitrary TCP port scans, inspect full TLS certificate chains, or bypass cross-origin restrictions. A blocked request is reported as inconclusive—not as a vulnerability. No results are sent to a server operated by this site.
