Hey Product Hunt,

I'm the maker behind Port Detective Pro at Automata Labs.

This started from a problem every Windows dev has hit a hundred times. You go to start a local server and get `EADDRINUSE: address already in use :::3000`. Task Manager can't tell you what's holding the port, so you drop into PowerShell, run `netstat -ano`, eyeball a PID, run `taskkill`, and hope you grabbed the right one. Every single time it yanks you out of your flow.

I wanted a real, easy to use app for this — not a webpage in a wrapper. So Port Detective Pro is built entirely in Rust on the backend. It gives you live, zero-lag visibility into your whole TCP/UDP stack (IPv4 and IPv6), and it stays light — typically under 50 MB of RAM, even on multi-hour runs.

What it does:
- **Type a port, see what owns it** — name, PID, full path, connection state. Instant.
- **Kill it safely** — it re-checks a secure process token before acting, so you never terminate the wrong app even if Windows recycles the PID a half-second later.
- **Port Guard** — pin the ports you care about (3000, 8080, 1433…), close the window, and a native background daemon watches them every 250ms. If something hijacks one, you get a Windows notification, and you can set a rule to automatically kill the intruder and relaunch the right process.
- **Docker-aware** — maps a host port back to the container and image that published it.
- **Remote scans, connection history, per-port notes, a Ctrl+K command palette,** and copy-any-row-as-a-`netstat`/`taskkill`/PowerShell command.

A few things I care about and want to be upfront on:
- **It's Windows 10/11 only.** It's a native app using Windows networking APIs — no Mac/Linux build today (happy to talk demand in the comments).
- **One-time purchase, fully unlocked.** No subscription, no in-app upsells, no license server to babysit. It runs fully offline.
- **Private by design.** Core features make zero external network calls. The only outbound traffic is stuff you explicitly trigger (a remote scan, or the Docker CLI lookup).

It's live on the **Microsoft Store** now, and there's a launch discount running.

I'll be here all day — would genuinely love your feedback, feature requests, and the worst port conflict you've ever had to debug. Fire away. 🙏
