witr

ps, top and lsof tell you what is running. witr tells you why. Point it at a process, PID, port, container or file and it traces the chain that explains it - systemd, supervisor, shell or cron - plus who started it, when, from where, and the warnings worth knowing. Run it bare for an interactive TUI with Processes, Ports, Containers and Locks tabs. Or script it: --short for a one-line chain, --json with real exit codes. One static Go binary for Linux, macOS, Windows and BSD.

Greplica

Greplica gives your engineering team and every coding agent a shared memory of the codebase. It continuously extracts decisions, constraints, gotchas, failed approaches, and file-level context from coding sessions, then retrieves only what matters for the task at hand. Unlike static docs or siloed agent memory, Greplica stays grounded in the repo, keeps knowledge fresh, and works across developers, agents, clones, and forks. It is open source, runs locally, and offers a managed shared mode.
