New Q Developer accounts were blocked exactly one week ago. If you have an active Pro subscription — or you've been using the free tier via Builder ID — you're now in a 12-month countdown to full end-of-support on April 30, 2027.
This review covers what Amazon Q Developer was, where it was genuinely useful, where it fell short of Cursor and Copilot, and the decision tree every existing user needs to work through before April 2027.
Verdict up front: Q Developer was the right tool for AWS-heavy Java shops that needed code transformation and compliance-grade IP indemnity at $19/user/month. For everything else — general-purpose AI coding, non-AWS backends, frontend work — Copilot or Cursor outperformed it throughout 2025-26, and the sunset just makes that choice official. New users should go straight to Kiro IDE.
The Sunset Explained: What's Going Away and What Isn't
Amazon announced Q Developer end-of-support on April 30, 2026. The timeline:
| Date | What happens |
|---|---|
| May 15, 2026 | New Free Tier account creation (via Builder ID) and new Pro subscription creation blocked |
| May 29, 2026 | Opus 4.6 removed from Q Developer Pro; Opus 4.5 and other models remain |
| April 30, 2027 | IDE plugins end-of-support; paid subscriptions terminate; all users lose access |
The IDE plugins — VS Code, JetBrains, Eclipse, and Visual Studio — will stay published on their respective marketplaces until April 2027, but with a deprecation notice pointing users to Kiro. If you have an existing subscription, your access continues until that date.
What is NOT going away: Amazon Q Developer inside the AWS Management Console and first-party AWS services (CodePipeline, CodeReview, CloudWatch) are unaffected. AWS is keeping the Q brand alive in its console tooling; it's specifically the IDE plugin product line and standalone subscriptions that are being retired.
The replacement is Kiro — a full IDE (VS Code fork, Code OSS base) built around spec-driven development, autonomous agents, and hooks. If you want the deep dive on Kiro's spec workflow and credit model, the Kiro IDE review has the full breakdown.
What Amazon Q Developer Actually Did
Before calling the migration, it's worth understanding what you're migrating away from. Q Developer was more than a code completion layer.
Inline code suggestions
Q Developer's autocomplete covered 15+ languages: Python, Java, JavaScript, TypeScript, C#, Go, Rust, PHP, Scala, Kotlin, SQL, Ruby, and others. Suggestions were context-aware within the open file and read the local project structure via the IDE. Quality was competitive with Copilot's 2025 baseline but consistently behind Cursor's Tab on cross-file completion — Q Developer didn't maintain the same long-range context window.
Agentic software development
The agentic mode let you describe a feature in natural language ("Add a Favorites API to this Lambda function") and Q Developer would analyze the repo, generate a plan, write code, and run tests. This was genuinely useful for AWS Lambda and DynamoDB patterns — the agent understood AWS SDK idioms and CDK constructs natively, not as learned patterns but as built-in grounding.
Free tier: 50 agentic requests/month. Pro tier: 1,000 agentic requests/month.
Code transformation — the standout feature
This was Q Developer's clearest differentiator. The transformation agent could automatically upgrade:
- Java 8 → Java 21 (or 11 → 17, 17 → 21): dependency refactoring, syntax modernization, breaking-change resolution
- .NET Framework → cross-platform .NET: modernization for projects stuck on Windows-only framework
Free tier: 1,000 lines/month. Pro tier: 4,000 lines/user/month (pooled at account level), with overage at $0.003/line.
A real-world example: a 20,000-line Java 8 codebase upgrade. At $0.003/line, the overage beyond the 4,000-line pool is $48. That's $48 vs weeks of manual migration work. For Java shops running legacy AWS services, this math is easy.
Security scanning
Q Developer's built-in security scanner detected credential exposure, log injection, SQL injection, and other OWASP-class vulnerabilities — then generated remediations in the context of your code rather than generic fixes. Coverage:
- Languages: Java, Python, JavaScript, TypeScript, C#
- Infrastructure-as-code: CloudFormation (YAML and JSON), CDK (TypeScript, Python), Terraform (HCL)
The IaC coverage was genuinely better than Copilot's at the same price point. Copilot's security features required GitHub Advanced Security ($49/user/month) to get to equivalent CloudFormation/Terraform analysis.
AWS Console integration
Q Developer in the AWS Console — the part that's not being shut down — answered questions about your live AWS environment: "Why is this Lambda cold starting slowly?", "What IAM permissions does this policy actually grant?", "Optimize this CloudFormation stack for cost." This was the product's second killer use case, and it remains fully operational post-sunset.
Free vs Pro: Plans You Can No Longer Sign Up For
| Feature | Free (was $0) | Pro ($19/user/mo) |
|---|---|---|
| Inline code suggestions | ✓ | ✓ |
| Agentic requests | 50/month | 1,000/month |
| Java code transformation | 1,000 LOC/month | 4,000 LOC/user/month (pooled) |
| .NET transformation | ✓ | ✓ |
| Security scanning | ✓ | ✓ |
| Reference tracking | ✓ | ✓ |
| IP indemnity | ✗ | ✓ |
| Admin dashboard + user management | ✗ | ✓ |
| SSO via IAM Identity Center | ✗ | ✓ |
| Data isolation (no training on inputs) | ✗ | ✓ |
| Model access | Latest available | Latest available + higher priority |
New signups are blocked as of May 15, 2026. If you're an existing Pro subscriber, your price and feature set remain locked until April 30, 2027.
Where Q Developer Was Genuinely Good
AWS-native context. The agent understood AWS SDK patterns, Lambda handlers, and CDK constructs at a depth that neither Cursor nor Copilot matched without extensive .cursorrules setup. For a team building and operating on AWS infrastructure daily, this saved real time.
Java legacy migration. The transformation agent's Java upgrade path was the product's most defensible use case. No other AI tool at $19/user/month offered automated Java 8 → 21 upgrades with dependency graph resolution. Teams maintaining large legacy Java services got measurable ROI from this feature alone.
Compliance-grade data handling (Pro). The Pro tier's data isolation — inputs not used for model training, combined with IP indemnity — was a serious enterprise differentiator. JetBrains and Tabnine both offer similar isolation, but Tabnine Pro starts at $39/user/month (more than double), and JetBrains AI Pro is $10/month without enterprise data controls.
IaC security scanning. CloudFormation and Terraform security analysis at the Pro price point was better value than GitHub Advanced Security for teams already on AWS.
Where Q Developer Fell Short
General-purpose code quality. Outside AWS patterns, Q Developer's code suggestions were average. Cursor's Tab completion and Copilot's inline suggestions both produced better cross-file context in everyday TypeScript, React, or Go work. The AWS-native strength was also a weakness: developers working across stacks found the suggestions less relevant.
Context window size. Q Developer's agent operated with a smaller effective context than Cursor Agent (which leverages full Sonnet/Opus context windows) or Cline. For large multi-file refactoring tasks — the kind where you need the agent to hold 20 files in mind simultaneously — Q Developer would lose track of changes made in earlier steps.
Frontend blind spot. React, Vue, Next.js, Svelte — Q Developer had no specialization here. Copilot and Cursor both offered better component-level completion and design-to-code workflows. For teams running full-stack projects
