Portia
Detects port collisions and kills the blocking process with one click.
Launch screenshots from Product Hunt, Jun 2026
A native macOS utility that detects and kills processes blocking a port, solving the problem of port collisions (EADDRINUSE) that developers encounter when running local servers. It targets developers using macOS, particularly those working on web development or backend services. The tool is delivered as a lightweight, event-driven Launch Agent that stays idle until a port collision occurs, then provides a one-click kill via native notification, eliminating the need for terminal commands like lsof.
