Port Inspector

About this tool

Static web dashboard that talks to a local read-only Python agent over 127.0.0.1 to show every TCP/UDP listener — protocol, address, port, scope (loopback / all interfaces / private / specific), owning PID, process name, user, even container hints. Sockets bound to 0.0.0.0 or :: are highlighted as reachable from outside, and the page suggests currently-free dev ports. The agent is pure standard library; runs as a systemd user service with autostart. No command-execution endpoint — read-only by design.
