A CLI tool that explains why any Linux process is running, what started it, and which ports and containers it owns
When a developer SSH into a server they didn't configure, figuring out why a given process is alive takes 10 to 30 minutes of manual ps, pstree, lsof, and systemctl chasing. The built-in Unix tools tell you what is running but give no causal chain: who launched this, what is keeping it alive, which socket does it hold, is it a container child or a systemd unit or a cron job. This CLI tool maps any PID to its full ancestry chain, launch origin, held ports, container context, and dependent services in one command, outputting a structured tree that gives a developer instant situational awareness on any unfamiliar Linux machine.

Gap Assessment
5 tools exist (Datadog, Sysdig, Grafana Labs, Witr, pstree / systemd-analyze) but gaps remain: Does not explain the causal WHY chain of a single PID in a one-shot CLI command on any arbitrary Linux machine. Requires agent installation, a Datadog account, and is priced at enterprise scale ($3.7B revenue). Not usable in a 30-second SSH session on an unfamiliar server.; Security and container runtime focus, not interactive process causality explanation for a dev debugging an unknown machine. Requires agent + cloud account. No standalone CLI that answers why a PID is running with parent chain + port + container context in one output..

| Product | Does | Missing |
|---|---|---|
| Datadog | Full-stack observability (metrics, logs, traces, APM, network monitoring) across cloud infrastructure; process agent collects per-host process lists. | Does not explain the causal WHY chain of a single PID in a one-shot CLI command on any arbitrary Linux machine. Requires agent installation, a Datadog account, and is priced at enterprise scale ($3.7B revenue). Not usable in a 30-second SSH session on an unfamiliar server. |
| Sysdig | Container and cloud security and observability using eBPF kernel instrumentation; surfaces process activity for threat detection. | Security and container runtime focus, not interactive process causality explanation for a dev debugging an unknown machine. Requires agent + cloud account. No standalone CLI that answers why a PID is running with parent chain + port + container context in one output. |
| Grafana Labs | Open observability platform; dashboards, metrics, logs, traces via Prometheus, Loki, Tempo stack. | Dashboards require pre-instrumented infrastructure. Cannot answer an ad-hoc why-is-this-running query on an uninstrumented server without setup time. No PID ancestry CLI. |
| Witr | Single-binary TUI that maps PIDs to port, service, container, and command ancestry. 17.8k GitHub stars. | Single-developer open-source project with no cloud layer, no team-wide process snapshot sharing, no audit trail, no API, no SaaS or paid tier. Linux-only. No structured JSON output for downstream tooling. No alerting when unexpected processes appear. |
| pstree / systemd-analyze | Bundled Unix tools that show process parent-child tree or systemd unit boot timing. | Shows tree structure but not the causal WHY: no port mapping, no container context, no launch trigger (cron vs systemd vs shell vs container entrypoint), no cross-referencing service dependencies. HN comments explicitly confirm it does not answer the question. |
