MEAN and MERN stacks are popular JavaScript-based web development frameworks that leverage Node.js across the entire stack, streamlining development and fostering code reuse. LAMP and LAMPy stacks combine powerful open-source technologies, providing scalability and flexibility. These stacks have garnered considerable traction, with Node.js being used by over 52% of professional developers, PHP consistently ranking among the top 5 most popular programming languages, and Python's popularity surging in recent years. MEAN, MERN, LAMP, and LAMPy stacks empower developers to build dynamic, scalable, and efficient web applications, offering cost-efficiency, streamlined development process, flexibility, continuous maintenance, and ubiquity. However, these stacks can present common challenges such as identifying performance bottlenecks, slow loading times, errors, database performance issues, and frontend responsiveness. New Relic quickstarts offer a streamlined approach to instrumenting your chosen stack and gaining deeper insights into your application's performance and health with pre-built dashboards and alerts.
