Accelerating AWS Development with Amazon Q Developer - AI Code Generation and Troubleshooting

This article explains how to make use of Amazon Q Developer for code generation in the IDE, troubleshooting in the AWS console, and code transformation.

Overview of Q Developer

Amazon Q Developer is an assistant for developers that makes use of AI, and it supports 15 or more programming languages. It provides code generation and completion in the IDE, natural language question answering in the AWS console, security scanning of code, and support for upgrading language versions. The Free Tier has monthly usage limits, and in the Pro Tier those limits are raised above the Free Tier.

Code Generation and Security Scanning

When you enter a comment or function signature in the IDE, Q Developer understands the context and automatically generates code. It can generate code that uses the AWS SDK, such as Lambda function handlers, DynamoDB queries, and S3 file operations. Security scanning detects vulnerabilities in code (SQL injection, hard-coded credentials, insecure encryption) and automatically suggests fixed code. The code transformation feature automates upgrades from Java 8 to Java 17 and performs the replacement of deprecated APIs and rewriting to use new language features.

Console Integration and Troubleshooting

Q Developer can be used not only in the IDE but also in the AWS Management Console. For natural language questions such as "Why does this Lambda function time out?" and "Are the settings of this security group secure?", it returns answers in the console's chat interface based on the current resource settings. One way to use it is to paste CloudWatch error logs into Q Developer and ask it to analyze the cause. When you ask about operating procedures in the console, it guides you through step-by-step procedures with links to the relevant service pages. Because Q Developer's answers are suggestions, you apply security-related configuration changes after checking them in the official documentation.

Code Transformation and Upgrade Support

Q Developer's /transform command automates version upgrades of Java applications (Java 8/11 → Java 17). It runs compatibility checks of dependent libraries, the replacement of deprecated APIs, and updates to build settings all at once, and presents the transformation results as a diff. For large Java projects, you accept the transformation results after checking them in the IDE. Support for migrating from .NET Framework to .NET Core is also provided. When you enter a description of a task, the /dev command analyzes the entire repository, suggests the necessary file changes, and creates them as a pull request. One approach is to leave the initial implementation of feature additions and bug fixes to Q Developer and have people review and finish it.

Q Developer Pricing

Q Developer's Free Tier lets you use code suggestions in the IDE with monthly limits, and it also includes question answering in the console. The Pro Tier costs approximately $19.00 per user per month, and its limits on code suggestions, code transformation, and security scanning are raised above the Free Tier (as of August 2026). Natural language question answering in the AWS console is available even in the Free Tier, and you can make use of it for troubleshooting errors and checking how to use services.

Agentic Task Automation

Besides one-off code completion, one way to use Q Developer is to entrust it with development tasks that span multiple steps. When you describe the feature you want to achieve in natural language, it understands the relevant files as a whole, assembles the necessary changes, and proceeds from implementation to testing as a single continuous flow. Developers can proceed with the work while reviewing and approving the suggestions at each step. Because you can receive support in large units by conveying the goal rather than giving detailed instructions one at a time, you can reduce the effort of routine implementation and refactoring. It is possible to use it in a way where humans manage the direction and quality while it takes over the implementation effort.

Understanding and Explaining Existing Code

Q Developer helps not only with writing code but also with understanding existing code. When you join an unfamiliar codebase, if you ask what a complex function or module is doing, it explains the intent and flow of the processing. This helps you grasp the overall flow in code that lacks documentation. When an error occurs, it presents an estimated cause and an approach to fixing it, so you can also shorten the time spent on troubleshooting. You can use it for onboarding new members and for investigating code that has been maintained over a long period.

Summary

Amazon Q Developer is an assistant that makes use of AI to accelerate AWS development. It provides code generation, security scanning, code explanation, and optimization suggestions in the IDE, and it also supports troubleshooting in the AWS console. With the /transform command, it automates version upgrades of Java applications.
