netshow

netshow is a lightweight, interactive TUI for monitoring active TCP connections and their associated processes with human-friendly service names (e.g. "Docker", "VS Code", "Plex"). It provides live connection counts, bandwidth monitoring with per-interface selection, and regex-powered search with live filtering.When run as root, it uses psutil for full fidelity process information; as a regular user, it falls back to lsof. Selecting a connection reveals process details including path, PID, resource usage, and open files. The interface supports keyboard navigation, sortable columns, and configurable refresh intervals.

Full process information requires root privileges. Falls back to limited information when run unprivileged.

netshow was created by Taylor Wilsdon and is written in Python. It can be installed via uvx, pip, or from source with uv.
