Overview
witr is a command line and terminal UI tool that answers one question: why is this running? Given a process, port, container or file, it traces back to the chain that started it, across supervisors, containers, services and shells. Tools like ps, lsof, ss and docker ps show what is running, but you must piece together the cause yourself. witr makes that cause explicit, with readable output, JSON or an interactive TUI.
Key features
