Overview

Kiro is an AI-powered development environment that brings structure to coding by turning your simple prompts into detailed specifications, technical designs, and implementation tasks. It bridges the gap between quick prototyping and production-ready code by maintaining context and documentation throughout the development process. Think of it as having an AI partner that not only writes code but also plans, organizes, and tracks your entire project from concept to deployment.

Frequently Asked Questions

What is spec-driven development?

Spec-driven development is Kiro's approach to turning simple prompts into comprehensive requirements, technical designs, and implementation tasks, keeping everything synchronized throughout the development process.

Is Kiro only for AWS users?

No, anyone can sign up with GitHub or Google. AWS integration is optional and provides additional capabilities.

How does it compare to other AI coding tools?

Kiro focuses on spec-driven, agentic workflows that automate planning, documentation, and best-practice enforcement, rather than just code suggestions like traditional AI assistants.

What programming languages does Kiro support?

Kiro supports any language that VS Code supports, making it language-agnostic and capable of working with most modern development stacks.

Will my code be used to train AI models?

Only if you're on the free tier and don't opt out. Pro and Pro+ users' code is never used for model training, with enterprise-grade privacy guarantees.
