Amazon Q Developer

Amazon Q Developer is an AI-powered coding assistant from AWS, available in freemium and Pro ($19/user/month) tiers, designed to help developers write, debug, transform, and secure code with deep integration into AWS cloud services and infrastructure.

Tested on a real AWS project, it correctly suggested IAM policies and generated working CloudFormation templates that referenced existing resources. The AWS account awareness — querying your actual Lambda functions, S3 buckets, and CloudWatch logs through natural language — is something no other AI coding tool offers today.

The code completion works across 15+ languages and handles single-line, multi-line, and full-function generation. Quality is solid for AWS-related code (Lambda handlers, CDK constructs, Terraform with AWS providers) but falls behind Copilot and Cursor for general frontend and mobile work.

The Java transformation agent is the standout enterprise feature. It upgrades Java 8/11 applications to Java 17/21, handling dependency updates, deprecated API replacements, and build configuration changes. It works best on standard Spring Boot applications.

Security scanning catches OWASP Top 10 vulnerabilities, hardcoded secrets, and crypto misuse inline with suggested fixes. The reference tracker flags generated code that closely matches open-source training data, which matters for teams with strict licensing policies.

Setup complexity varies. The Free Tier just needs an AWS Builder ID — no account or credit card. Pro requires IAM Identity Center, which is powerful for enterprise governance but adds friction for smaller teams. The IDE plugin ecosystem is broad: VS Code, JetBrains, Visual Studio, Eclipse, plus the AWS Console, CLI, Slack, and Teams.

Bottom line: Amazon Q Developer is the best AI coding assistant for teams deeply invested in AWS. For general-purpose coding without significant AWS usage, Copilot or Cursor deliver better results at comparable prices.
