Top 9 APM Tools for Node.js Performance Monitoring
When a Node.js app slows down, you don’t get a clear picture right away. One service stalls, another spikes in CPU, and somewhere in between, requests start piling up. You can’t fix what you can’t see. Application Performance Monitoring (APM) tools close that gap. They capture request traces, latency, and errors across your stack — showing you what’s running slow and why.
