Final Verdict
CodeWhisperer/Amazon Q Developer is the best AI coding tool for AWS-heavy development — its service-specific suggestions for Lambda, S3, DynamoDB, and CDK go beyond what general tools produce. The free individual tier is competitive. For general coding outside AWS, GitHub Copilot or Cursor are stronger.
