A process manager running as a daemon, primarily used for Node.js applications. It launches processes in the background, monitors them, restarts them after errors, provides logs, and can support application scaling.
Why it matters
Keeps Node.js applications running: restarts them after crashes, starts them after server reboots, and collects logs. A simple supervisor that prevents processes from silently dying overnight.
What's missing without it
Without supervision, any unhandled error takes down the application permanently — requiring manual restart in the morning after hours of downtime.
When it is used
On every production server running Node.js applications: launching, monitoring, logging, and restarting.
How we use it
PM2 maintains a running Node.js backend or SSR frontend and automatically restarts it after failure.
