PM2 vs Process Monitor for Linux

PM2 is a daemon process manager for managing applications and keeping them online. PM2 Runtime is an open-source process manager; PM2 Plus adds monitoring for Node.js production applications. Runtime supports cluster mode, zero-downtime reloads, watch and restart, startup scripts, log management and memory-based reloads. For containers, pm2-runtime can run Node.js applications with process fallback, flow control, monitoring and source-map support. PM2 Plus lists a web monitoring interface, application overview, issue tracking, custom metrics, server health checks and Node.js V8 monitoring. Its alerts include email and Slack notifications, while Enterprise adds rule-based alerting. The AI Assistant connects Claude, Cursor and other MCP-compatible assistants to monitoring data through OAuth with a PM2.io account. Documentation covers Docker, cloud providers, Heroku, AWS Elastic Beanstalk, Nginx and deployment workflows. Runtime costs nothing, and Plus costs $79 a month.
