# Manfath > Manfath (Arabic: منفذ, "port") is a free, open-source macOS menu bar app that shows every localhost port on a developer's machine. It scans listening TCP/UDP ports every 3 seconds, lets the user kill a stuck process with one click, and exposes any local port to the public internet through a tunnel (Cloudflare, ngrok, or a custom provider). It runs entirely on the user's machine — no accounts, no telemetry, no upsell. ## At a glance - **Name:** Manfath (English) / منفذ (Arabic) - **Platform:** macOS 14 Sonoma or later (universal binary — Apple Silicon and Intel) - **Distribution:** Free direct download (signed + notarized .dmg), Homebrew Cask (`brew install --cask Dnymte/tap/manfath`), GitHub Releases - **License:** MIT - **Source:** https://github.com/Dnymte/manfath - **Website:** https://manfath.dev - **Built with:** Swift + SwiftUI + AppKit; SwiftPM core library, XcodeGen, no third-party runtime dependencies - **Privacy:** Everything runs locally. The app makes no network calls except when the user explicitly creates a tunnel. ## What it does Manfath sits in the menu bar and answers three questions developers ask all day: 1. **What is listening on my machine right now?** Every 3 seconds it re-scans listening ports across TCP, UDP, IPv4, and IPv6, and shows each one with its process name, PID, and protocol. Sortable by activity, filterable by name or PID. 2. **How do I free this port?** One-click kill on any row. Manfath sends SIGTERM first, escalates to SIGKILL if the process refuses to exit. No `sudo lsof -i :3000` then `kill -9 ` two-step. 3. **How do I share this port with someone outside my network?** One click creates a public URL through Cloudflare Tunnel, ngrok, or a custom command. The URL goes to the clipboard automatically. ## Who it's for Frontend, backend, and full-stack developers on macOS who run multiple local servers (Next.js, Vite, Rails, Django, Express, FastAPI, Postgres, Redis, etc.) and need to know what's running, kill what's stuck, and occasionally share a local site with a teammate or a phone for testing. ## Why it exists Existing tools force a developer to either: - memorize `lsof -nP -iTCP -sTCP:LISTEN` and `kill -9` incantations, or - pay for a SaaS dashboard that uploads telemetry, or - juggle ngrok's CLI in a separate terminal. Manfath collapses all three into a menu-bar icon, ships as a single signed app, and stays out of the way. ## Common questions Manfath answers - "How do I find a port on Mac Terminal?" / "Mac terminal command to find what's on a port" - "How to list open ports on macOS from the Terminal" / "show listening ports mac terminal" - "What's running on port 3000?" / "What process owns this port?" - "Address already in use" / "EADDRINUSE" / "bind: address already in use" - "How do I kill a process on a port?" / "How do I free a port on macOS?" - "Free alternative to ngrok" / "How to expose localhost to the internet" - "Why is my port stuck after I closed the terminal?" ### Canonical answer: how to find a port on Mac Terminal Open Terminal (Cmd+Space → "Terminal") and run: ```sh lsof -nP -iTCP:3000 -sTCP:LISTEN ``` Replace `3000` with the port you want. The `PID` column is the process ID, the `COMMAND` column is the program. `lsof` is preinstalled on every macOS version — no setup. For all listening TCP ports at once: `lsof -nP -iTCP -sTCP:LISTEN`. For just the PID (scripting): `lsof -ti :PORT`.

The CLI is always available on macOS; Manfath is the one-click GUI on top.
