Wharfy

Wharfy is a macOS menu bar utility designed to bring clarity and control to your development environment. Key features include: • View all listening development ports • Identify the application or process that opened each port • Receive warnings for servers exposed to your local network • Safely stop processes using occupied ports • Command-line interface and MCP server for advanced control This tool eliminates the guesswork of 'port already in use' errors by showing the full parent chain of processes and their associated applications, including specific developer tools. It helps maintain system security by flagging dev servers bound to 0.0.0.0, which are visible to everyone on your network, allowing you to filter and manage them efficiently. Wharfy provides a safe stopping mechanism, employing SIGTERM with a grace period before SIGKILL, ensuring entire process trees are terminated without impacting your shell or IDE. Wharfy also intelligently handles different process types, such as Docker containers (using `docker stop`) and macOS services (providing warnings before termination to prevent system disruption). For professional users, Wharfy Pro remembers port activity, providing historical context and preventing recurring port conflicts. This makes Wharfy an indispensable tool for developers, system administrators, and anyone managing local development servers on macOS who needs precise port management and enhanced security.
