Amazon Q Developer

Amazon Q Developer is AWS's AI coding assistant, renamed from CodeWhisperer in mid-2024 and significantly expanded. Its defining feature is deep AWS service awareness: unlike generic coding tools, Q Developer understands your IAM policies, CloudFormation stacks, CDK constructs, and broader AWS architecture. It can generate code that correctly references your specific AWS resources, suggest least-privilege IAM policies, and help debug cloud infrastructure problems in context.

The tool includes a code transformation feature that automatically upgrades legacy codebases — migrating Java 8/11 to Java 17/21 or Python 2 to Python 3 — across entire repositories. The agent can be assigned complex tasks like refactoring a service, writing unit tests for an existing module, or implementing a new feature end-to-end. Q Developer integrates with VS Code, JetBrains, Visual Studio, and the AWS Console directly.

Key capabilities include AWS-context-aware code generation, automated code transformation for language version upgrades, inline completions in 15+ languages, agentic task execution, security vulnerability scanning, and direct integration with the AWS Console. For teams building on AWS, it provides infrastructure-level context that no other coding tool offers.

Pricing: Free tier includes unlimited code completions and 50 agentic developer chats per month. Pro tier costs $19 per user per month and adds unlimited agentic chats, code transformation for larger projects, and extended context. Enterprise pricing is available with additional compliance controls.

Limitations: Outside of AWS development, Amazon Q Developer is not particularly competitive compared to Cursor or GitHub Copilot. The free tier's 50 agentic chats per month runs out quickly on active projects. The tool provides less value for GCP, Azure, or non-cloud development.

Best suited for development teams building on AWS who want an AI assistant that understands their cloud infrastructure — IAM, CloudFormation, CDK, and AWS services — alongside standard coding capabilities.
