VisualEther turns Wireshark PCAPs into readable sequence diagrams, and its MCP server lets Claude Code analyze a capture and explain failures in plain English — frame numbers as evidence. Free Community edition; a 45-day trial unlocks AI analysis, triage & CI.

Hi Product Hunt 👋 Founder here.

I spent years building satellite networks with an LTE air interface — reconstructing a call flow meant thousands of packets across MAC/RLC/PDCP/RRC/S1AP that you rebuild in your head and redraw on a whiteboard. VisualEther draws that conversation straight from the capture.

It's built on tshark, so anything Wireshark can dissect, it can diagram. The part I'm most excited about is the AI angle: a raw PCAP instantly blows an LLM's context window, so the MCP server extracts only the messages and fields that matter — Claude Code reads kilobytes of structured data instead of megabytes of raw logs, then explains failures with frame numbers as evidence.

The free Community edition renders PDF sequence diagrams from any capture. A 45-day trial unlocks the AI/MCP analysis, browser-based session triage, and larger diagrams.

I'll be here all day — ask me anything about the FXT format, the MCP tool design, or packet analysis in general.

Finally something that makes digging through PCAPs less painful. The sequence diagram view of a captured TLS handshake was surprisingly clear, and pointing Claude at the file actually surfaced the exact frame where the retransmit happened.

@emirhan265511 Thank you. "The exact frame where the retransmit happened" is exactly the point: an answer you can trace to a frame, not a hunch. And yeah, TLS finally reads like a conversation as a diagram. If you throw a messier capture at it next, I'd love to hear what Claude finds. 🙏
