Free app, open source. Enjoy.

I've got a design background, started building a lot more lately, couldn't stand how opaque the process is to see what ports are occupied and what local servers are running. So I built WhatThePort.

It shows you:

- what local servers are running - how long they've been running - their resource use - notifies you if one spikes - auto-kill old servers (opt-in) - give easy ways to launch the local urls - add shortcuts to my Vercel preview url, or Codex/CCode sessions that created it, and shortcuts to resume in my terminal of choice - has charts to see spikes - allows you to resume sessions in the terminal - auto-tags stale servers if your workspace is cold - and more.

Also added a TUI for it today since I know many devs will prefer having access to it.

Enjoy, share feedback.
