Key Differences Explained

Development Philosophy

Kiro: Starts with specifications and generates complete, production-ready implementations. Uses EARS format and steering files to maintain context.

Q Developer: Assists with existing code, focusing on completion, explanation, and transformation. More traditional copilot approach.

AWS Integration

Kiro: Cloud-agnostic with general AWS support. No special AWS service integration.

Q Developer: Deep AWS integration - understands IAM policies, CloudFormation, Lambda, and can generate AWS-specific code patterns.

Code Quality Features

Kiro: Automated hooks for tests, documentation sync, and CI/CD integration. Focuses on complete delivery pipeline.

Q Developer: Security scanning, code quality analysis, and automated code reviews. More focused on code health.

🎯 Our Recommendation

For most developers: If you're building new applications and want AI to handle the entire development lifecycle, choose AWS Kiro. Its spec-driven approach with Claude 4 produces more complete, production-ready code.

For AWS-heavy teams: If you're deep in the AWS ecosystem or need to modernize legacy code, Amazon Q Developer is the better choice with its specialized AWS knowledge and transformation capabilities.

Consider using both: They complement each other well - Kiro for new feature development, Q Developer for AWS integration and code modernization.
