Manfath is a free, open-source macOS menu bar app that lists every listening localhost port on your machine, shows the process and PID behind each one, lets you kill any process with one click, and exposes any local port to the public internet via Cloudflare or ngrok. It runs entirely on your machine — no accounts, no telemetry. Key features include:
- Scan: Every listening port, every 3 seconds, zero config. TCP, UDP, IPv4, IPv6 — with the process name and PID behind each one.
- Kill: Stuck process on :3000? One click, it's gone. SIGTERM first, SIGKILL if it misbehaves — with zero terminal yoga.
- Tunnel: Share localhost with a public URL in one line. Cloudflare, ngrok, or your own — Manfath wires it up and copies the link.
Manfath sees processes, not frameworks — which means it sees everything: Vite, Next.js, Rails, Django, Express, FastAPI, Postgres, Redis, Docker-mapped host ports, and so on. It's MIT-licensed, with no paid tier, no upsell, no telemetry. The full source is on GitHub.
