BiuSniff.
A PyQt6 network packet analyzer for authorized environments, with protocol inspection, DNS and TLS context, live capture, and PDF capture reports.
Seeing what moves across a network.
BiuSniff makes packet-level learning tangible in a controlled environment. It turns captured traffic into readable protocol details, raw hex views, DNS answers, TLS server-name context, and reportable capture data.
Capture, inspect, understand.
Packet decoding
Live capture data is organized into readable protocol, address, port, payload, and raw-hex context.
DNS & TLS context
DNS answers and TLS Server Name Indication help make network conversations easier to interpret.
Capture reports
Selected packet data and capture metadata can be exported as a concise PDF reference.
Focus: Supporting careful network analysis learning only on systems and environments where capture is authorized.
