Intro

What is Kiro?

Kiro is an AI-powered integrated development environment (IDE) designed to take software projects smoothly from prototype to production. Unlike traditional editors like VSCode or platforms focused on conversational 'vibe coding', Kiro introduces structure to AI coding through spec-driven development. It acts as an advanced tool tailored for working with agents, integrating natively with the Model Context Protocol (MCP) and state-of-the-art models like Claude 3.7 Sonnet. Developed alongside AWS infrastructure, the platform brings enterprise-grade security, mature engineering practices, and background agent automation to developers looking for a powerful alternative to Cursor or Replit.

Kiro FAQ

While tools like Cursor are excellent at inline code generation, Kiro is built from the ground up to support spec-driven development. It transitions developers away from unstructured 'vibe coding' by converting raw prompts into technical designs, system architectures, and agent hooks before generating any code.
