10-hop depthSSRF guardedLatency tracking

Checks run from this server using the selected user-agent string. JavaScript is not executed; crawler identity and browser behavior are not reproduced. Shared links prefill a new test, not a saved report.

Manual redirect tracing

Automatic following is disabled so every hop, status code, destination, and response time stays visible.

Crawler-aware checks

Switch user agents to compare what desktop browsers, mobile browsers, and common crawlers receive.

Defensive fetching

Private networks, metadata addresses, unsupported schemes, credentials, and unusual ports are blocked before requests are sent.
