Could you build this?
Partial While terminal user interface (TUI) frameworks make the UI straightforward, deep packet inspection and cross-platform low-level packet capture at wire speed require systems programming expertise.
What it would actually take: Built with Rust or Go using libpcap/BPF wrappers and TUI libraries like Ratatui or Bubbletea. The hard part is efficient, non-blocking zero-copy packet processing, protocol decoding across multiple networking layers, and managing elevated OS networking privileges safely without dropping frames during traffic spikes.
