Overview
- Kiro entered a free preview on July 14, offering English-only chat through Anthropic models with alternative AI engines due in future releases.
- The IDE converts natural-language prompts into structured specifications—user stories, acceptance criteria and design artifacts—before generating any code.
- Event-driven hooks trigger background AI agents on file saves, creations or deletions to automate testing, documentation updates and boilerplate tasks.
- Built on the open-source Code OSS editor, Kiro preserves existing Visual Studio Code settings and plugins while supporting the Model Context Protocol for external tool integration.
- After the preview ends, AWS will introduce tiered subscriptions: a free plan with 50 interactions, a Pro tier at $19/month for 1,000 interactions and a Pro+ tier at $39/month for 3,000 interactions.
