Java: The Enterprise Standard
It’s no surprise that Java remains a top choice for developers using New Relic. As a dominant force in enterprise-level applications, Java boasts one of the most mature and comprehensive APM agents available. New Relic’s Java agent offers deep, out-of-the-box
instrumentation for a massive ecosystem of app servers, databases, and frameworks like Spring and Hibernate. This means you get detailed transaction tracing, performance metrics, and error diagnostics with minimal setup. For large-scale, mission-critical systems where stability and in-depth visibility are non-negotiable, Java provides a rock-solid foundation for observability.
Python: The All-Around Contender
Python's famous versatility, spanning web development, data science, and AI, makes it a critical language to monitor effectively. New Relic provides a robust Python agent that supports popular frameworks like Django, Flask, and Celery. This allows teams to trace requests across distributed services, identify slow database queries, and monitor background task performance. As Python continues to power everything from nimble startups to complex machine learning pipelines, having first-class observability through New Relic ensures that performance keeps pace with rapid development cycles.
Node.js (JavaScript): For High-Performance I/O
In the world of microservices and real-time applications, Node.js is king. Its event-driven, non-blocking I/O model is built for handling concurrent connections efficiently, but it can also make performance bottlenecks tricky to diagnose. New Relic’s Node.js agent is designed to navigate this asynchronous landscape, providing clear insights into event loop performance, slow callbacks, and external service calls. For teams building fast, scalable network applications, APIs, or serverless functions, the combination of Node.js and New Relic offers the clarity needed to maintain high performance.
Go: Built for the Cloud-Native Era
Developed at Google with concurrency and efficiency in mind, Go has become a go-to language for cloud-native infrastructure, including tools like Docker and Kubernetes. Its lightweight goroutines make it easy to build highly concurrent services. New Relic fully supports Go with a dedicated APM agent, allowing developers to monitor performance without sacrificing the language's famed efficiency. As more companies build their backend systems on Go for its speed and simplicity, New Relic provides the essential visibility to ensure those services are not just fast, but also reliable.
.NET: The Microsoft Ecosystem Powerhouse
For organizations invested in the Microsoft stack, from web applications built on ASP.NET to services running on Azure, the .NET framework is central. New Relic offers extensive support for both the traditional .NET Framework and modern, cross-platform .NET (formerly .NET Core). The agent provides detailed diagnostics for applications, including visibility into SQL Server performance, and integrates smoothly into the Visual Studio environment. This ensures that whether you're maintaining legacy enterprise software or building new cloud-native apps, you have a consistent and powerful observability solution.
Ruby: The Developer-Friendly Choice
Ruby, particularly through the Ruby on Rails framework, has long been praised for its emphasis on developer productivity and happiness. New Relic’s Ruby agent is one of its earliest and most polished offerings, tailored to the conventions of the Rails ecosystem. It provides deep insight into the full request-response cycle, from routing and controller execution to ActiveRecord query performance and view rendering. For the many startups and established companies that rely on Rails to build and iterate quickly, New Relic offers the guardrails to ensure that speed of development doesn't come at the cost of performance.
