## Health v2 (maintenance only)
Score: 58/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 58, release rhythm 35, longevity 100
- inputs: {"age_days": 5748, "days_push": 255, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases, no_license
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
Supervisor is a client/server process control system for UNIX-like operating systems that starts, stops, restarts, and monitors processes as subprocesses of supervisord. It provides a supervisorctl CLI, a web interface, and an XML-RPC API for managing and observing process state.

## Use cases
- keep a crashed process running by automatically restarting it
- manage multiple app processes on a server without writing rc.d scripts
- let non-root users start and stop services without shell access
- monitor the up/down status of background workers
- control long-running Python or Node processes in production
- restart a process automatically when it uses too much memory
- query and control processes programmatically via XML-RPC

## When to choose
- you need simple, reliable process supervision on Linux, macOS, Solaris, or FreeBSD
- you want a CLI and web UI to start/stop/restart application processes
- you need automatic restart of crashed processes with accurate status reporting
- you want to delegate limited process control to non-root users

## When to avoid
- you are on Windows - Supervisor does not run there at all
- you need a full init system or PID 1 replacement like systemd, launchd, or runit
- you are already using systemd, which covers most of the same use cases on modern Linux
- you need container-native supervision (use the container runtime or a supervisor like s6 in that context)
