Could you build this?
Partial While standard system CLI wrappers are easy, PortMon requires native macOS low-level programming with libproc, privileged root helpers, process tree traversal, and Docker engine socket integration.
What it would actually take: The app requires native Swift/Objective-C interacting directly with Darwin kernel socket tables via libproc and sysctl APIs, alongside an XPC-privileged helper tool installed via SMJobBless. It also must parse container sockets (Docker/OrbStack) to resolve internal proxy ports to container IDs and walk the process parent hierarchy reliably without crashing or blocking the UI thread. This demands deep systems-level macOS engineering experience.
