Portabella

Portabella shows you every server running on your Mac, and lets you do something about it. Open your menu bar and see each program that's listening for connections: its port, what it is (Next.js, Vite, Django, Express and many more, identified from evidence and honestly labelled when it's a guess), its process, and its address. Open it in your browser, copy its URL, or stop it. STOPS THINGS PROPERLY Portabella asks a server to quit politely, then checks that it stayed stopped. If something restarts it, you're told instead of left guessing. It will never stop system programs, other users' programs, or itself. A PANEL THAT STAYS PUT Detach the list as a floating, always-on-top panel that snaps to the edges of your screen and fades out of the way until you need it. Quiet notifications tell you when servers appear, vanish or come back. ON YOUR IPHONE Pair your iPhone by comparing a six-digit code on both screens, and see your Mac's servers from the couch: open the ones that are reachable, copy addresses, and stop them with Face ID. Servers that only listen on the Mac itself can be shared with your iPhone, one at a time, through an encrypted tunnel that lasts 30 minutes. Everything between your devices is signed and end-to-end encrypted. There is no account and no Portabella server. WIDGETS AND SHORTCUTS Widgets for your desktop and home screen show the list, always labelled with how fresh it is. Shortcuts and Siri can list servers, check whether a port is in use, open or stop a server. FOR THE TERMINAL A free, dependency-free command line tool and full-screen terminal interface with JSON output, documented exit codes, and NO_COLOR support. LOOKS LIKE YOU Thirteen colour themes plus any colour you choose, in light and dark, with accessibility built in: VoiceOver, Dynamic Type, Increase Contrast and Reduce Motion are all respected. PRIVATE BY DESIGN No accounts, no analytics, no tracking. Command lines and file paths never leave your Mac. ABOUT STOPPING SERVERS Apps from the Mac App Store run in a sandbox, which can't end other programs. To stop servers, Portabella works with the free Portabella Companion, a small helper you download from tomhodgins.com/software/portabella. Without it, everything else works and Portabella explains what's missing. Requires macOS 26 and iOS 26.
