What it does

Kiro is an agentic engineering platform built and operated by AWS that provides both an IDE and a CLI. You give it natural language prompts, architectural designs, or existing docs, and it generates executable specifications, implementation tasks, code, and property tests. It is designed for individual developers, growing software teams, and enterprise engineering organizations building software.

  2. Kiro: Property based testing

    Property based testing

    Use caseA developer adds rate limiting to an export endpoint and generates automated property tests to verify it across all inputs.

    Use caseA technical architect identifies conflicting requirements in a project specification before writing any implementation code.

  4. Kiro: Auto model routing

    Auto model routing

    Selects the optimal model for a given task according to complexity. It balances model quality, latency, and operational expense across frontier and open weight options.

    Use caseA programmer submits varying coding tasks and lets the system pick between lightweight models for simple work and frontier models for complex work.
