AWS Kiro AI: Amazon’s Bold New Agentic IDE Turning ‘Vibe Coding’ into Viable Software
AWS unveiled Kiro AI in mid-July 2025 as a specification-driven agentic IDE, available in a free public preview on kiro.dev, and powered by Anthropic Claude Sonnet 4 (with Claude 3.7 as a fallback) while built on a VS Code (Code-OSS) core. Kiro converts plain English prompts into full project specs—requirements.md, design.md, and tasks.md—before writing code, and keeps these specs in sync with the evolving codebase. The platform uses autonomous coding agents that coordinate across multiple files to implement requirements and update documentation, with Agent Hooks that trigger tests and maintenance tasks on file saves. Kiro includes an Agentic Chat panel
