Amazon CodeWhisperer is AWS's generative AI-powered coding companion that accelerates software development with context-aware code suggestions trained on billions of lines of code, including Amazon's internal codebase and AWS best practices. The Individual tier is completely free and provides real-time code completions across 15+ languages (Python, Java, JavaScript, TypeScript, C#, Go, Rust, PHP, Ruby, Kotlin, C, C++, Shell, SQL, Scala), integrated security scans detecting hard-to-find vulnerabilities with suggested remediations, and reference tracking that identifies when suggestions match public code with licensing information. The Professional tier ($19/user/month) adds policy management for enterprise governance, SSO/SAML integration, and administrative controls. Unlike generic AI assistants, CodeWhisperer excels at generating AWS-optimized code for services like Lambda, S3, DynamoDB, and EC2, understanding AWS SDK patterns and infrastructure-as-code frameworks (CloudFormation, CDK, Terraform). With plugins for VS Code, JetBrains IDEs, AWS Cloud9, and command-line support, plus the ability to scan entire projects for security issues pre-deployment, CodeWhisperer helps developers build secure, well-architected cloud applications faster while maintaining code quality and compliance.
