The Real Source of Puppeteer Memory Leaks: Chrome, Not Node.js

Puppeteer memory leaks are commonly misdiagnosed because developers focus on Node.js heap metrics when the actual problem lies in uncontrolled Chrome child processes. This comprehensive guide provides practical, step-by-step profiling techniques—including memory monitoring, baseline measurement, and heap snapshot analysis—that developers can immediately apply to identify and eliminate real leaks. Mastering these profiling methods is critical for building production-ready browser automation applications that reliably manage system resources.
