Amazon CodeGuru Profiler vs YourKit .NET Profiler

Amazon CodeGuru Profiler collects runtime performance data from live applications and recommends ways to improve performance and find CPU bottlenecks. It is designed for continuous profiling of production applications with minimal overhead. Interactive flame graphs show CPU and latency analysis, including which code paths use the most resources. Machine learning recommendations identify expensive methods and explain their cause, impact, and possible resolution.

The service can detect anomalies in application profiles and, when configured, send an Amazon SNS notification for a new anomaly. It supports Java, JVM languages such as Scala and Kotlin, and Python 3.6 or later. Java and other JVM languages can be profiled for CPU and heap summary; Python profiling covers CPU wall-clock time. Applications may run on EC2, ECS, EKS, Fargate, Lambda, or on premises. The agent can be enabled in JVM applications from the command line or application code and is also used for Lambda applications. An AWS account is required, with IAM permissions controlling access. The agent collects stack traces, not parameter names or values, variable values, or application data.

YourKit.NET Profiler analyzes CPU performance and memory use in.NET and.NET Core applications. It can profile servers, Windows services, and other.NET applications locally or remotely in development, testing, and production. CPU results appear as call trees or hot spots; memory tools visualize the object heap and object graph. Plugins integrate with Microsoft Visual Studio and JetBrains Rider. The profiler shows slow SQL queries and ASPX requests and supports MongoDB and Cassandra. More than 20 inspections can identify duplicated objects, unclosed database connections, inefficient collections, and I/O operations. Remote profiling can create an SSH tunnel to an application on another machine. A.NET API manages profiling modes and captures snapshots, while command-line tools can automate profiling and performance monitoring in continuous integration. Version 2026.9 supports.NET 5 through.NET 10 and.NET Framework 4.x, with Linux, macOS, and Windows downloads. A single-seat annual subscription costs $99 a year; a perpetual single-seat license costs $129 as a one-time purchase. A 15-day trial is listed, and qualifying open source project contributors and Microsoft MVPs can contact sales regarding a free license.
