Portia

Key Features

• •One-click process kill (SIGTERM / SIGKILL): With a native notification, users can instantly terminate the offending process without opening Terminal, saving time and avoiding manual commands.
• •Background Launch Agent — zero idle CPU: Portia operates as an event-driven Launch Agent that only activates on port collisions, consuming no CPU resources until needed, making it ideal for continuous monitoring.
• •Full PID, process name & path: The full version displays complete process details (PID, name, file path) so users can verify the target before killing, reducing risk of terminating critical services.
• •Menu bar port overview (Lite): The free version provides a menu bar icon that shows blocked port numbers and basic process names, giving a quick at-a-glance status without opening any app.
• •Monitors any user's processes (full): Unlike the Lite version, Portia Full can detect port conflicts from background services or other user accounts, essential for complex development environments.
• •Native notifications with Strike button: When a port collision occurs, a macOS notification appears with the process info and a clickable 'Strike' button, enabling one-click resolution without leaving the current app.
• •No shell modifications: Portia does not edit .zshrc, add plugins, or require shell hooks. Install the Launch Agent once and forget it, keeping the terminal environment clean.
• •Apple Silicon native, macOS 26+: Built as a single signed and notarized binary exclusively for Apple Silicon and macOS 26 Tahoe, ensuring optimal performance and security.

Use Cases

• •A web developer running Node.js, Python, or Rails servers often hits port 3000 or 8080 collisions after a crash. With Portia, they see a notification with the process details and click 'Strike' to free the port, resuming work without touching Terminal.
• •A system administrator troubleshooting a background service that failed to release a port after an update can use Portia’s full version to identify the stale process across any user account and kill it instantly, reducing downtime.
• •A developer using an IDE like VS Code or Xcode encounters an EADDRINUSE error while debugging. Portia provides a non-intrusive notification that allows them to resolve the conflict without leaving their coding environment, preserving focus.
• •A QA engineer running multiple test servers on different ports may encounter lingering processes. Portia’s menu bar overview shows all blocked ports, and with a single click they can clear the port and restart tests quickly.
• •A power user who frequently switches between projects using the same port number (e.g., 8080) can rely on Portia to automatically detect and kill the old process before starting a new server, eliminating manual cleanup steps.

Who is this for?

Portia is designed for macOS developers (web, backend, mobile), DevOps engineers, system administrators, and IT support staff who frequently manage local network services. It also suits QA engineers testing servers in local environments and any power user tired of manually hunting ports with lsof and kill. The tool is ideal for those using Apple Silicon Macs with macOS 26 or later who want a lightweight, native solution that doesn’t clutter their shell configuration or consume CPU resources. Both free and paid tiers ensure accessibility for individuals and teams seeking a friction-free port conflict resolution experience.
