Kiro

Spec-driven development is Kiro's approach to turning prompts into requirements, architectural designs, and sequenced tasks before implementing them with parallel agents, ensuring the final code matches the specification and is maintainable.

Kiro uses automated reasoning to check requirements for contradictions and gaps before coding, and then validates behavior with property-based tests that assert rules across all inputs, catching edge cases that unit tests often miss.

Kiro supports Anthropic Claude, open-weight models, and an 'Auto' mode that selects the best model for each task based on complexity, latency, and cost.

Yes, Kiro offers a headless CLI that can run in CI/CD to review pull requests, fix bugs, and run automated tasks like adding tests or updating documentation without opening an editor.

Yes, Kiro is built and operated by AWS, providing IAM/SSO authentication, usage dashboards, cost management controls, IP indemnity, governance, and administration controls suitable for enterprise-grade security and reliability.

Kiro uses a credit-based pricing model with no daily or weekly rate limits. It offers pre-paid overages for cap overages and add-on credits, ensuring predictable costs without surprise bills.
