What is Kiro?

Kiro is an agentic AI development environment built by Amazon, designed to take developers from prototype to production with structure, speed, and precision. Unlike conventional AI editors that rely on free-form chat, Kiro uses spec-driven development to convert natural language prompts into structured requirements with EARS notation, architectural designs, and discrete implementation task lists. Advanced agents autonomously execute tasks, fix bugs, and solve complex problems across large codebases. Kiro also supports agent hooks for event-triggered automation, MCP for external tool connections, a CLI for terminal and headless CI/CD use, and autopilot mode for fully autonomous execution, making it one of the most structured and powerful AI development environments available.
