Could you build this?
Partial A terminal UI and basic ping or port checks are easy to vibe-code, but robust network path tracing and topology inference require specialized systems networking knowledge.
What it would actually take: A full implementation requires a Go codebase utilizing low-level network probing (such as Paris traceroute techniques, ICMP/TCP raw sockets, or gopacket) coupled with a TUI framework like Bubble Tea and custom graph-layout algorithms. The difficult challenges are handling cross-platform raw socket permissions, multi-path network topology mapping, and decoupling network discovery logic to run smoothly in a Go WebAssembly sandbox. Success requires seasoned systems programming and internet routing protocol expertise.
