What is Port Detective?

Port Detective is a Windows utility designed to make port conflict troubleshooting simple, fast, and safer for developers and technical teams. The app helps users identify what process owns a port, what executable is behind it, and whether it can be safely terminated. It is especially useful for resolving EADDRINUSE errors that occur when development servers, local services, Docker containers, or background processes compete for the same port. The free edition includes a live listening-port viewer, instant lookup, process details, and five safe kills so users can test the workflow. Port Detective Pro unlocks unlimited safe kills protected by process-token verification to reduce the risk of terminating the wrong recycled PID. Its Port Guard feature runs as a system-tray watchdog that monitors critical ports and can automatically remove unwanted processes. The Pro edition also adds TCP and UDP visibility across IPv4 and IPv6, remote host scanning, Docker bridge scanning, and Docker host-to-container port mapping. Users can inspect process lineage, keep per-port notes, export connection history to CSV or JSON, and use a Ctrl+K command palette for faster navigation. The software is built in Rust with Tauri 2, signed for Windows, and designed to use minimal system resources. Port and process data stays on the workstation for local inspection, and the product does not require telemetry, accounts, or subscriptions. Port Detective gives Windows developers and IT professionals a dedicated workflow for finding, fixing, and preventing port conflicts without relying on scattered system tools.
