CLI and TUI tool that explains why processes, services, and ports are running by tracing causality chains across supervisors, containers, and shells.
witr — Why Is This Running? Skill by ara.so — Daily 2026 Skills collection. witr is a Go CLI/TUI tool that answers "why is this running?" for any process, service, or port. Instead of leaving you to correlate ps, lsof, ss, systemctl, and docker ps manually, witr makes the causality chain explicit — showing where a running thing came from, how it was started, and what chain of supervisors/containers/shells is responsible.
