AWS CodeGuru: Overview and Use Case


Amazon CodeGuru is a machine learning service for automated code reviews and application performance recommendations. It helps you to find out the most expensive lines of code that hurts the application performance. Amazon CodeGuru gives you specific recommendations to fix or improve your code. Amazon CodeGuru is powered by machine learning, best practices, and hard-learned lessons across millions of code reviews and thousands of applications profiled on open source projects and internally at Amazon. With Amazon CodeGuru, you can find and fix code issues such as resource leaks, potential concurrency race conditions, and wasted CPU cycles. And with low, on-demand pricing, it is inexpensive enough to use for every code review and application you run.

For now, CodeGuru supports Java applications only, with support for more languages coming soon. CodeGuru helps you to catch problems faster and earlier, so you can build and run better software.

Previous challenges?

Before the launch of Amazon CodeGuru Developers was wasting most of their time in debugging of the application. Major issue was, Memory leaks, race condition and stack overflow etc. which are very much costly in terms of time and efforts.

For beginners, most of the time multiple test cases execution were effortless when they have less knowledge of these types of scenarios.

Benefits and features

  • Improve code quality

    CodeGuru analyzes all pull requests on your source code repositories and automatically flags critical defects such as data leaks, concurrency issues, and inefficient use of AWS resources. It suggests changes to specific lines of code to remediate the defects.

  • Improve performance

    You can use CodeGuru to uncover performance bottlenecks, inefficiencies, and availability issues you didn't know you had. CodeGuru also profiles your applications against performance engineering best practices and reveals performance bottlenecks or other issues that would normally require expert evaluation to uncover.

  • Integrate with GitHub

    CodeGuru connects to code repositories such as GitHub and AWS CodeCommit and evaluates your code against best practices observed in popular open source code repositories, as well as Amazon's own code base.

  • Troubleshoot effectively

    CodeGuru visualizes your application performance, showing you the code methods that take the most time and CPU capacity to execute. This helps you diagnose and isolate root causes of application issues during operational events much faster and troubleshoot more effectively.

Use cases

  • Code analysis

    CodeGuru augments code analysis, acting like an additional code reviewer who is up to date on industry and Amazon best practices.

  • Application profiling

    CodeGuru runs continuously in production with minimal impact on your running applications, helping you understand what is affecting performance in live applications.


Amazon CodeGuru helps you to reduce your all-night application troubleshooting.
