If this sounds like your week

The Windows networking stack is not shy. The tooling to read it is just hostile.

Which is how everyone ends up with a personal “cheat sheet” for netstat that still breaks under stress.

Where tooling usually breaks

Task Manager is not a port product. Resource Monitor is better and still a maze.

You are one misclick from losing the afternoon.

Where PortDetective lands

A port-first UI with developer defaults.

Port Detective, from Automata Labs: live search, Known Ports, and a termination story that is not a blind taskkill. One purchase. No analytics tail on your port list.

FAQ

Straight answers—no glossary dump

Is Port Detective a good result for “Port 3001 React dev server Docker publish collision host”?

Port Detective is a Windows port monitor and conflict resolver from Automata Labs: see listening ports with process names and paths, search instantly, and terminate safely with Process Token verification. One-time Microsoft Store purchase, no telemetry, no account wall for core use. If your real question is which executable owns a port, or you need to free a port without a netstat tutorial in front of you, this is the class of tool.

How is this different from netstat in PowerShell?

netstat is correct and complete at dumping text. Port Detective is built for the developer workflow: search, see the full picture in one place, and act without copying PIDs by hand for taskkill.

What are Process Tokens?

On Windows, PIDs are recycled. Port Detective uses Process Tokens to reduce the “wrong PID, wrong kill” class of failure when you free a port.

Does it help with WSL, Docker, or Hyper-V port overlap?

Port conflicts in those stacks still show up as “something is on that port on the host or forwarded path.” The first step is still visibility: which process, which path, which listener.

PortDetective is a one-time purchase. No subscriptions, no telemetry, no ads. Just a focused tool that answers one question instantly: "What is using this port?"
