Show HN: NetSour, the modular packet analyzer TUI
Developer thegoodduck published NetSour, a modular, terminal-based packet analyzer, to GitHub and posted it to Hacker News seeking feedback.
A developer going by thegoodduck published NetSour, a modular packet analyzer built as a terminal user interface (TUI), to GitHub on August 26, 2026, per a Hacker News Show HN post submitted the same day.
The project is available on GitHub under the handle thegoodduck. As the name suggests, NetSour is designed around a modular architecture, allowing components of the packet analysis workflow to be composed or extended independently — though the specifics of those modules are documented in the repository rather than the HN post itself.
The tool operates entirely within the terminal, positioning it for use in environments where graphical interfaces are unavailable or undesirable, such as remote servers accessed over SSH. Packet analyzer TUIs occupy a niche alongside established tools like tcpdump and Wireshark's command-line companion tshark, aiming to offer more structured, navigable output than raw command-line dumps while avoiding the overhead of a full GUI.
The Show HN submission carries a single point and no comments at time of writing, and the author's stated purpose is gathering feedback: "Hey! Built this and would like some feedback," thegoodduck wrote in the post text. No funding, team size, or organizational affiliation is mentioned in any available source.
No forward-looking roadmap or planned features were described in the submission. Further details on supported protocols, installation, and module structure are available in the NetSour repository.
