Amazon CodeGuru

Amazon CodeGuru is an enterprise-grade developer tool suite that leverages machine learning to automate code reviews and application performance profiling. By 2026, CodeGuru has become deeply integrated into the Amazon Q Developer ecosystem, serving as the specialized engine for deep semantic analysis and runtime behavior optimization. It consists of two primary components: CodeGuru Reviewer, which utilizes program analysis and machine learning to detect critical issues, security vulnerabilities, and hard-to-find bugs during development; and CodeGuru Profiler, which provides interactive visualizations of application performance in production. The tool's architecture is built on models trained on millions of lines of open-source and internal Amazon code, allowing it to identify non-obvious defects such as resource leaks, race conditions, and inefficient CPU utilization. As the market shifts toward 'Shift-Left' security and 'FinOps' for cloud resources, CodeGuru's ability to map code efficiency directly to infrastructure costs positions it as a vital utility for organizations managing high-scale distributed systems. It supports major languages like Java and Python, with expanded support for JavaScript, TypeScript, and C# via the Amazon Q integration layer.
