AuthHound

Analyze your RADIUS log

Paste FreeRADIUS radiusd -X output or a Windows NPS event (6272/6273/6274, copied from Event Viewer) below.

🔒 Parsing happens in your browser. Your log never leaves your machine. Verify it: open DevTools → Network and watch nothing get sent while you analyze. The parser is open source. When a paste cannot be diagnosed, the page records a content-free fingerprint (format, server version, which modules appear, reason code) so the gap can be fixed; log text is only ever sent if you choose to share a redacted copy.
No log handy? Try a sample:

Supported: FreeRADIUS radiusd -X debug output (plus radius.log lines and radtest output) and Windows NPS events 6272/6273/6274 copied from Event Viewer as text or XML. The samples above are examples, not your data. No accounts, no history, nothing saved; the analyzer diagnoses a moment; continuous history and alerting is the paid product.
