Amazon CodeGuru Profiler
What Amazon CodeGuru Profiler is
Amazon CodeGuru Profiler collects runtime performance data from live applications so teams can investigate resource use and performance bottlenecks. It is designed to profile production applications continuously with minimal overhead. Interactive flame graphs display CPU and latency analysis, highlighting the code paths that use the most resources. Machine learning recommendations identify expensive methods and describe their cause, impact, and possible resolution. The service can also detect anomalies in application profiles and, when configured, send an Amazon SNS notification about a new anomaly.
CodeGuru Profiler supports Java and other JVM languages, including Scala and Kotlin, as well as 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 can run on EC2, ECS, EKS, Fargate, Lambda, or on premises. The profiling agent can be enabled in JVM applications from the command line or application code, and can also profile Lambda applications. It collects stack traces, but does not access function parameters, variable values, or application data. Data is encrypted at rest and in transit. Using the service requires an AWS account, with IAM permissions controlling access to its resources. A 90-day free tier is available; after it ends, standard sampling-hour pricing applies.
Who it suits
It suits teams running Java, other JVM, or Python applications that want ongoing production profiling, flame graph analysis, or recommendations for expensive methods. It is also relevant for teams that need profile anomaly notifications or profiling across the listed AWS compute environments and on-premises applications.
What it does well
- Profiles production applications continuously with minimal overhead.
- Interactive flame graphs show CPU and latency by code path.
- Recommendations explain expensive methods and their possible resolution.
- Can notify through Amazon SNS when it detects an anomaly.
- Stack traces are collected without application data or variable values.
What to know first
- Requires an AWS account and IAM access permissions.
- The free tier lasts 90 days before sampling-hour pricing applies.
- Python profiling covers CPU wall-clock time.
Limits
The Amazon CodeGuru Profiler Free Tier is free for 90 days; standard sampling-hour pricing applies afterward. Python profiling covers CPU wall-clock time, while Java and other JVM languages can be profiled for CPU and heap summary.

As aws.amazon.com lists them, read 8 Oct 2026. The maker's own page has the final word.
Getting started
- Open the CodeGuru Profiler website.
- Create or use an AWS account and configure IAM permissions for access.
- For a JVM application, enable the profiling agent from the command line or application code.
- For Lambda applications, use the profiling agent to profile the application.
- Start with the 90-day free tier, then use the applicable sampling-hour pricing.
Verdict
Choose Amazon CodeGuru Profiler for supported Java, JVM, or Python applications when continuous profiling, flame graphs, and method recommendations fit the work. It also provides anomaly detection and optional Amazon SNS notifications. Look elsewhere if the application language or Python profiling scope does not fit, or if an AWS account is not suitable.
