The AI coding assistant for AWS shops

Amazon Q Developer is the AI coding assistant built by AWS — which means it's the only major coding AI with native understanding of every AWS service, CLI flag, and CloudFormation/CDK resource. Built on the Claude family of models, it has caught up to Cursor and Copilot on raw code quality, and surpasses them on AWS-specific work: debugging Lambda errors, optimizing DynamoDB queries, writing IAM policies that don't leak, and migrating Java 8 monoliths to Java 17 in days. If your stack lives in AWS, Q Developer is the default pick in 2026.

Who it's for: Backend engineers and DevOps teams working in the AWS ecosystem. Enterprise IT teams that need security scanning, code transformation at scale, and SSO integration with AWS IAM Identity Center.

Key features

AWS Native AWS integration

Best-in-class knowledge of AWS services. Ask it to write a Lambda with proper IAM, S3 with lifecycle policies, or a CDK construct — it knows the latest APIs, pricing implications, and common pitfalls. Beats every other AI on AWS-specific code.

Transform Agentic code transformation

Q's killer feature for enterprise. Migrate Java 8 to 17, .NET Framework to .NET 8, or Windows to Linux in days, not months. Plans the changes, generates the diff, opens the PRs. Saved AWS's own internal teams thousands of hours.

Security Inline security scanning

Scans every AI-generated line for security issues (OWASP Top 10, secrets, injection) before commit. Catches what Copilot and Cursor miss. Inline fixes, not just lint warnings.

CLI Agentic CLI & IDE

Q CLI for terminal workflows (think Claude Code for AWS), plus full VSCode and JetBrains plugins. Chat, inline edit, multi-file refactor, and Amazon Q for business chat in Slack/Teams.

The honest take

✓ What works

Best AWS-specific code generation — knows every service, every SDK quirk
Code transformation is genuinely 10x for legacy modernization
Security scanning is built-in, not a paid add-on
Free tier is generous (50 agent requests/mo, unlimited completions)
SSO, audit logs, and data residency via AWS IAM

✗ What doesn't

Less polished editor experience than Cursor or Windsurf
Slower on non-AWS code than the GPT-4/Claude-based tools
Multi-file refactor agent is not as good as Cursor's Composer
Locked into the AWS ecosystem for the best results

Verdict

If you live in AWS — Lambdas, CDK, IAM, CloudFormation — Amazon Q Developer is the AI to use in 2026. It's caught up to Cursor/Copilot on general code quality, and the AWS-native context, security scanning, and code transformation features are unmatched. For polyglot or non-AWS work, Cursor or Windsurf is still better.
