PM2 – production process manager

PM2 is a production process manager designed primarily for Node.js and Bun applications.

It keeps applications running, automatically restarts failed processes and provides a command-line interface for managing application lifecycles.

The software includes a built-in load balancer, zero-downtime reloads, process monitoring, log management and startup-script generation. Although focused on JavaScript runtimes, PM2 can also launch Python and Ruby scripts, shell commands and executable binaries.

This is free and open source software.
