Kiro

Kiro is a cloud-based agentic IDE that structures AI coding through spec-driven development. It converts prompts into detailed specs, architectural designs, and sequenced tasks executed by parallel agents on your local machine or in the cloud. The platform verifies code correctness with property-based tests, catching edge cases that unit tests miss. It supports multiple LLMs including Anthropic Claude, open-weight models, and an Auto mode that selects the best model per task. Kiro integrates with GitHub and GitLab for PR review, and offers a headless CLI for CI/CD. Built and operated by AWS, it provides enterprise-grade security, SSO, and cost controls. Best for developers and teams working on complex, large codebases who need rigorous validation and structured workflows, especially in enterprise environments.
