WireScopeSTARTED AS ANDY FIDDLER
After an internship exploring how AI services move data, my mentor left me a challenge: you’ve used the inspector — now build one.
So I built a traffic inspector that follows an HTTP request down to its TCP connection, packets and the bytes on the wire.
EXPLORE WIRESCOPE ↗- L7HTTP request
- L4TCP connection
- L3IP packet
- L2Field & bytes

THE INTERESTING PART
Bridging application-level inspection and packet analysis: TLS termination, HTTP/2 streams, field offsets, structural JSON diffs and portable offline reports.
HONEST BOUNDARIES
Requests link to packets by connection, not one-to-one. Missing bytes stay visible as gaps. macOS tests pass; Windows capture and real AI-service traffic are still unverified.
