Amazon Q Developer Review: Enhancing AWS Development with AI

Amazon Q Developer, the evolution of Amazon CodeWhisperer, promises a robust set of features aimed at enhancing the developer experience, especially for those heavily involved in AWS. In this detailed review, we’ll explore the functionalities of Amazon Q Developer, its integration capabilities, and its competitive stance in the market. We will also delve into its performance metrics, ease of installation, and overall user experience.

Overview of Amazon Q Developer

Amazon Q Developer has evolved from its predecessor, Amazon CodeWhisperer, to offer a more comprehensive suite of features. Initially, CodeWhisperer could generate code in an IDE and conduct security reviews but lacked a chat window and code explanations. The rebranded Amazon Q Developer addresses these gaps with a chat feature that can explain code and a host of new capabilities, making it particularly useful for AWS developers.

Currently, Amazon Q Developer runs in several environments, including Visual Studio Code, Visual Studio, JetBrains IDEs, the Amazon Console, and the macOS command line. This wide range of compatibility ensures that developers can use the tool in their preferred development environment without needing to switch tools.

Key Features and Capabilities

Amazon Q Developer boasts a wide array of features designed to assist developers throughout the coding process:

  • Code Completions: Q Developer excels in completing lines of code, doc strings, and common code blocks such as if/for/while/try. However, it falls short in generating full functions for specific use cases.
  • Code Chat: The chat feature can explain code, which is particularly useful for understanding complex codebases or learning new programming concepts.
  • AWS Integration: Q Developer integrates deeply with AWS, allowing users to chat about AWS capabilities, review resources, analyze bills, and architect solutions based on AWS well-architected patterns and documentation.
  • Multilingual Support: It supports code in multiple programming languages, including Python, Java, JavaScript, TypeScript, C#, Go, Rust, PHP, Ruby, Kotlin, C, C++, shell scripting, SQL, and Scala. This extensive language support makes it versatile for a wide range of development projects.
  • Security Scanning: Q Developer can scan code for vulnerabilities and suggest remediations, enhancing the security aspect of the development process.
  • Reference Tracking: The reference tracker detects if a code suggestion is similar to publicly available code, providing repository URLs and project license information, or filtering them out if necessary.

Installation and Setup

The installation process for Amazon Q Developer varies depending on the environment but generally follows a straightforward procedure:

  • Visual Studio Code: Installable from the Visual Studio Code Marketplace or the Extensions sidebar. Post-installation, authentication to AWS is required.
  • JetBrains IDEs: Available in the JetBrains marketplace for IDE plugins. After installation, a reboot of the IDE and authentication to AWS are necessary.
  • Visual Studio: Part of the AWS Toolkit, installable from the Visual Studio Marketplace, followed by AWS authentication.
  • macOS Command Line: Involves downloading a DMG file, running the disk image, and installing the CLI program and menu bar icon.
  • AWS Console: Requires appropriate IAM permissions for non-root users to use Q Developer.

The authentication process can be somewhat confusing due to multiple options and steps that involve bouncing between the IDE and web browser. However, the frequency of re-authentication has been reduced to every three months, simplifying long-term use.

Performance and Evaluation

Performance metrics for Amazon Q Developer have shown promising results. According to AWS, Amazon Q Developer Agent achieved the highest scores of 13.4% on the SWE-Bench Leaderboard and 20.5% on the SWE-Bench Leaderboard (Lite). SWE-Bench is an evaluation framework consisting of 2,294 software engineering problems drawn from real GitHub issues and corresponding pull requests across 12 popular Python repositories.

While these scores are impressive, it is important to note that neither has been independently verified by SWE-Bench, and the ranking on the Lite Leaderboard has since dropped to #3. Despite these caveats, the reported scores suggest a strong performance in coding capabilities.

In practical use, Amazon Q Developer’s performance in predictive inline code generation and other tasks has been mixed. For instance, a Python prompt to upload a file to an S3 bucket generated accurate code suggestions, albeit with minor hiccups such as illegal characters and import issues. Subsequent tests, including generating arrays of fake users and unit tests, had varying degrees of success, highlighting areas for improvement.

Competitive Analysis

Amazon Q Developer faces stiff competition from other AI-powered code assistants, such as GitHub Copilot, JetBrains AI, and Tabnine. Each tool has its unique strengths and weaknesses:

  • GitHub Copilot: Supports conversations in multiple natural languages and offers numerous extensions from various vendors, making it highly versatile. However, its integration with AWS is not as deep as Q Developer’s.
  • JetBrains AI: Seamlessly integrates with JetBrains IDEs and offers robust code completion and assistance features, but it lacks the AWS-specific capabilities of Q Developer.
  • Tabnine: Known for its efficient and accurate code completions across multiple languages, Tabnine also lacks the AWS-centric features of Q Developer.

In the broader context, Q Developer also competes indirectly with large language models (LLMs) and small language models (SLMs) that are proficient in coding, such as Code Llama, StarCoder, Bard, OpenAI Codex, and Mistral Codestral. These models offer diverse capabilities but may not have the specialized focus on AWS that Q Developer provides.

User Experience and Feedback

The user experience with Amazon Q Developer has generally been positive, particularly among developers who frequently work with AWS. The deep integration with AWS services and well-architected patterns provides significant value, streamlining various aspects of cloud-based development.

However, some users have reported challenges with the tool’s setup and initial configuration, particularly around authentication. The mixed performance in certain code generation tasks also indicates room for improvement.

Overall, the feedback highlights the tool’s potential to enhance productivity, especially in AWS-centric development environments, while also pointing out areas where further refinement is needed.

Future Prospects

Looking ahead, Amazon Q Developer has the potential to become an indispensable tool for developers, particularly those heavily involved in AWS. The continuous improvement of its AI models, better integration with development environments, and expanded language and feature support could further solidify its position in the market.

Moreover, as the competitive landscape evolves, we can expect Amazon to introduce new features and enhancements to stay ahead. The integration of multiple AI models to route tasks intelligently already sets a precedent for future innovations.


Amazon Q Developer represents a significant advancement in AI-powered coding assistance, particularly for developers working within the AWS ecosystem. With its extensive feature set, deep AWS integration, and robust language support, it offers a compelling tool for enhancing developer productivity and efficiency.

While there are areas for improvement, particularly in setup and code generation consistency, the overall capabilities and potential of Amazon Q Developer make it a valuable addition to the toolkit of any AWS developer. As AI continues to evolve, tools like Amazon Q Developer will play a crucial role in shaping the future of software development, driving innovation, and streamlining workflows across the industry.
