AWS-native AI coding assistant with codebase scanning, migration, and security vulnerability detection
Amazon Q Developer (formerly CodeWhisperer) is AWS's AI coding assistant with deep integration into the AWS ecosystem. Beyond code completion, it scans codebases for security vulnerabilities using SAST, provides AWS API and service recommendations, and automates application migration and modernisation tasks — including Java upgrade and .NET to Linux migrations. Free for individual AWS users, it is the natural AI coding choice for AWS-centric development teams.
Amazon Q Developer is a strong fit if its core strengths match your workflow, budget, and support needs. Use the quick signals below before opening the full review.
Amazon Q Developer's differentiation is clear: it is the AI coding assistant built by the cloud platform that most enterprise applications run on. For developers spending the majority of their time writing Lambda functions, CDK stacks, Step Functions workflows, and SDK integrations, Q Developer's AWS-contextual recommendations provide value that no third-party tool can fully replicate.
Q Developer's integrated SAST scanner identifies hardcoded secrets, insecure random number generation, SQL injection vulnerabilities, XSS vectors, and references to known CVEs in the codebase. Unlike standalone SAST tools that run as a separate pipeline step, Q Developer surfaces these findings inline in the editor as the code is written — shifting security left into the development moment rather than the CI/CD gate.
When writing code that interacts with AWS services, Q Developer suggests correct SDK method signatures, recommends least-privilege IAM policies for the operation being performed, and provides CloudFormation and CDK resource snippets calibrated to what the code actually needs. For teams building cloud-native applications where IAM misconfiguration is a significant security risk, this contextual guidance reduces both bugs and security issues.
Q Developer's migration capability automates Java major version upgrades — transforming Java 8 or 11 codebases to Java 17 or 21 with dependency updates and API changes handled programmatically. For organisations managing large Java legacy codebases where manual upgrade is prohibitively time-consuming, this automation represents concrete engineering hours saved.
Score: 8.4/10 — Best AI coding assistant for AWS-centric teams; value drops sharply for non-AWS development contexts.
