Assess
Amazon Q Developer (formerly CodeWhisperer) is AWS's AI coding assistant, with particular strengths for teams building on AWS services and a free tier — though the product has grown into a full autonomous coding agent.
Why It's in Assess
Q Developer excels in a specific niche: teams building on AWS. It has specialised knowledge of CloudFormation, CDK, Lambda, and other AWS services that generic models lack. In April 2025 it scored 66% on SWE-Bench Verified, placing it among the top-performing coding agents at the time.
- Free tier: Individual tier with no credit card required — though capped at 50 chat interactions and 10 agent invocations per month
- AWS integration: Deep integration with the AWS Console, VS Code, JetBrains, and Eclipse
- Security scanning: Built-in code scanning for security vulnerabilities (a genuine differentiator)
- Transformation: Upgrades legacy Java applications automatically (Java 8/11 → 17, with broader framework upgrades also supported)
- Cost estimation: Added in October 2025 — can query AWS service pricing and estimate workload costs directly in your IDE
- Underlying model: Claude Sonnet powers the chat experience
Tradeoffs
For general-purpose coding tasks outside the AWS ecosystem, Q Developer doesn't offer a clear advantage over Copilot or Cursor. The free tier caps (50 chats/month) limit meaningful evaluation without committing to a paid plan.
When to Consider It
- Your team is heavily AWS-focused
- You need built-in security scanning as part of your workflow
- You want autonomous coding agent capabilities tightly integrated with AWS tooling
