The deployment worked fine on-prem. Then the team containerized the application for Kubernetes, and the PDF generation service started failing intermittently. The error logs pointed to jsreport's child process spawning — Node.js inside a Docker container, with the reporting service trying to launch headless Chromium inside that Node.js process. The layered process management, the user permission model in the container, the memory limits — it all compounds. Getting jsreport running reliably in a container environment takes work that has nothing to do with generating PDFs. That's a common trigger for evaluating alternatives. This article is for .NET teams considering IronPDF as the replacement. If you're not switching, the architecture comparison section still maps out the tradeoffs worth understanding. Architecture difference — this matters first jsreport is a reporting server. IronPDF is a .NET library.…
