Process manager — a PM2 equivalent using launchd/systemd for persistence

macpmd

A process manager for macOS and Linux — a PM2 equivalent using launchd or systemd for persistence and crash recovery.

macpmd makes it easy to manage long-running processes. Start, stop, restart, and monitor processes from the command line. Processes are automatically registered with the system service manager (launchd on macOS, systemd on Linux) so they survive reboots and recover from crashes.

Features

• Process management — add, start, stop, restart, and delete processes
• Batch operations — operate on multiple processes at once, or use --all
• Process listing — view all processes with status, PID, uptime, restart count, and service state
• Log management — stdout/stderr redirected to ~/.local/share/macpmd/logs/ with automatic rotation
• Log tailing — view recent output, follow in real-time, or show all process logs with coloured prefixes
• Exit code logging — process exit codes and signals are recorded in the log
• Service integration — launchd plists (macOS) or systemd units (Linux) auto-installed for boot persistence and crash recovery
• Sudo support — start processes with --sudo for elevated privileges
• Zero dependencies — stdlib only, no external packages required
• Coloured output — TTY-aware ANSI colours for status display

Requirements

• Python 3.12+
• macOS (launchd) or Linux (systemd)

Installation

pip install macpmd

Or run directly with uv:

uvx macpmd

Quick Start

# Add a process (name auto-derived as "server")
macpmd add "node server.js"

# Add with an explicit name
macpmd add "python3 worker.py" --name my-worker

# Add with sudo
macpmd add "python3 server.py" --name my-app --sudo

# List all processes
macpmd list

# View logs
macpmd logs my-app
macpmd logs my-app --follow
macpmd logs --all
macpmd logs --all --follow

# Start a stopped process
macpmd start my-app

# Start all stopped processes
macpmd start --all

# Restart a process
macpmd restart my-app

# Stop multiple processes
macpmd stop my-app worker

# Stop all processes
macpmd stop --all

# Remove a process entirely
macpmd delete my-app

How It Works

macpmd spawns processes in new sessions (start_new_session) so they survive the parent terminal closing. Process state is tracked in ~/.local/share/macpmd/state.json and logs are written to ~/.local/share/macpmd/logs/<name>.log.

When you add a process, a service file is automatically installed:

macOS (launchd)

A plist is installed in ~/Library/LaunchAgents/ (or /Library/LaunchDaemons/ for --sudo) with:

• KeepAlive: true — launchd restarts the process if it crashes
• RunAtLoad: true — the process starts automatically at login

Linux (systemd)

A unit file is installed in ~/.config/systemd/user/ (or /etc/systemd/system/ for --sudo) with:

• Restart=always — systemd restarts the process if it crashes
• WantedBy=default.target — the process starts automatically at login

This gives you PM2-style process management backed by your platform's native process supervisor.
