How to Use Kiro in 2026: Step-by-Step Guide
AWS's AI coding agent IDE that uses spec-driven development — writing requirements, design, and tasks from a feature description, then autonomously implementing and iterating on code.
Kiro is Amazon Web Services' AI coding agent IDE, launched in preview in 2025. It takes a spec-driven approach to AI coding: instead of generating code from a single prompt, Kiro first produces a human-readable specification (requirements, design, implementation tasks) and iterates on that spec with the developer before writing code.
What Kiro Does Well
Spec-driven development is Kiro's key design decision. When a developer describes a feature, Kiro doesn't immediately write code — it first generates a structured specification: user requirements, system design, and a task breakdown. The developer reviews and edits the spec before code generation begins. This approach catches misunderstandings early and produces more predictable, better-scoped implementations.
Autonomous task execution carries spec tasks to completion without constant prompting. Kiro can implement multiple tasks sequentially, run tests, fix failing tests, and iterate — producing a working implementation rather than a code snippet that requires manual integration.
AWS-native integration gives Kiro deep hooks into AWS services. It understands the developer's AWS account context, can provision resources, and generates infrastructure code (CDK, CloudFormation) alongside application code.
"Hooks" automation triggers background agents to run automatically on file save, test run, or other IDE events — applying consistent code review, documentation generation, or security checks without manual invocation.
Who Kiro Is For
Kiro targets developers building on AWS who want more structured AI coding assistance than GitHub Copilot provides. It is available in free preview (2025); production pricing to be announced. Works as a standalone IDE or VS Code extension.
What You'll Need
- A Kiro account (free to create)
- A modern web browser or the Kiro app
Getting Started
Create Your Account
Visit https://kiro.dev and sign up for a free account. You'll need an email address to register.
Start Your First Conversation
Once logged in, you'll see the main chat interface. Type a question or task in the input box and press Enter. Kiro supports spec-driven-development, autonomous-coding, aws-integration, test-generation, code-review — start with a simple text prompt to get familiar.
Pro Tips
- Be specific: The more context you provide, the better the response. Instead of "write an email," try "write a professional follow-up email to a client who hasn't responded in two weeks."
- Iterate: If you don't get what you need, ask for clarification or refinement: "Make it shorter" or "Use a more formal tone."
- Use examples: Show Kiro what format you want by including an example in your prompt.
- Save useful conversations: Most platforms let you name and revisit conversations — organize by project or topic.
Common Use Cases

- Responses seem generic or unhelpful
- Add more context to your prompt. Specify the audience, tone, length, and format you need. Try starting over with a clearer description of your goal.
- The tool isn't responding or is slow
- AI chatbots can experience high traffic. Refresh the page and try again. Check the service's status page if issues persist.
- Output is too long or too short
- Explicitly specify the length: "in 100 words," "as a brief summary," or "in detail with examples."
