The scenario is hauntingly familiar to any backend engineer: you deploy a fleet of Headless Chrome instances to handle PDF generation, web scraping, or automated testing. On your local machine with 32GB of RAM, everything purrs. But the moment it hits a production container, the OOM (Out of Memory) reaper arrives. Within minutes, the resident set size (RSS) of your Chrome processes balloons, devouring every megabyte of available RAM until the kernel kills the process. In the world of server-side automation, Chrome is a hungry beast. It is a browser designed for rich user experiences, not necessarily for the lean, ephemeral life of a server process. To run it effectively at scale, we must move beyond the basic puppeteer.launch() and treat Chrome as a high-performance resource that requires surgical tuning. Why Does Headless Chrome Consume So Much Memory? The fundamental challenge lies in Chrome's architecture. It is built on a multi-process model designed for security and stability in a
