Kiro

Kiro is a spec-driven agentic IDE by AWS, starting at $20/month for premium models. It converts prompts into structured requirements, architectural designs, and sequenced tasks implemented by parallel agents. The tool validates code using property-based tests that catch edge cases missed by unit tests. It supports multiple models including Claude and open-weight models, and offers features like plan-to-PR workflows, integration with Figma and Terraform, and enterprise-grade controls. Kiro is built for developers and teams who want structured, reliable AI-assisted coding with predictable credit-based pricing. Typical use cases include building complex features, debugging, and reviewing PRs with automated reasoning.
