OpenProcMon vs Supervisor

OpenProcMon is a free, open-source process monitor for 64-bit Windows. It tracks process, file system, registry, and network activity in real time, with filters for process name, PID, operation, path, result, or category. Its interface includes a process tree, activity summaries, and call-stack views with per-frame module resolution. The tool reads and writes Sysinternals Process Monitor .PML logs, including logs made with the original Process Monitor. Developers can use its Rust SDK to connect to the driver, choose monitored activity, set filters, and consume parsed events programmatically. For AI-assisted capture and analysis, the procmon-cli MCP server operates over stdio and has setup instructions for clients including Claude Code, Claude Desktop, Codex, and Cursor. Capture tools can export filtered results as PML, CSV, or XML. The v0.5.0 release offers a Windows x64 ZIP with the GUI, CLI/MCP server, console example, skill, and guides. Live capture needs Administrator privileges to load the kernel driver; analyzing an existing .PML file does not. The project is MIT-licensed and its Rust rewrite is described as under active development.

Supervisor is a free client/server system for starting, monitoring and controlling processes on UNIX-like operating systems. It can restart processes after crashes and report their status. Administrators set per-process options in an INI-style configuration file, including failed-process restarts and automatic log rotation. Priorities and groups let related processes be started or stopped together.

Control is available through a command-line client, an optional browser interface and an XML-RPC interface. The browser view can display and control process status when the HTTP server is enabled; authentication can be required for commands over UNIX-domain or TCP sockets. Supervisor also has an event-notification protocol usable by programs in any language and extension points for Python developers. It can be installed with pip or from a downloaded distribution, including on systems without internet access. It is intended for project- or customer-related processes, not as a replacement for init as process ID 1. It runs on supported UNIX-like systems and does not run under Windows.
